- Here we see a teardown of a 4R44E transmission of a Mazda B3000 3.0 V6. This unit is also on the Ford Ranger and Ford Explorer. Although the unit changes in name, they're virtually the same unit as I explain in the video. 4R44E has 4 pinion planets on the front and rear. 4R55E and 5R55E have 6 pinion planets. 5R55E has an added speed sensor and reluctor on the output shaft for an added signal for the computer to make a 5th gear. Most of the parts are interchangeable between the 3 including valve body. The computer is the one responsible to make this transmission shift 5 times. The added gear is between 1st. and 2nd. applying the overdrive band to give you that extra gear that some call it 2nd prime.
Holly crap no wonder why transmission repairs are so expensive, there's so many pieces that make the transmission work. Great job.
Thanks Hiram. I was an industrial equip mechanic for 20 years; I've never seen such thorough training while performing a machine disassembly. Thank you for sharing your knowledge of your trade.
Your video is one of the very best. You speak clearly and explain a lot as you go along. I hope you live long and prosper.
I have three transmissions two 5r 55 East and 14044 or 55 e. I plan to take the good parts out of all three and rebuild One transmission so that my wife can go to work. I look at it this way I'm gaining experience and pushing my knowledge skills above and beyond what I know now. Thank you to the guy that made the video I'm sorry I don't not good with names.
Hello Hiram, I am a builder also, been building about 38 years and build foreign and domestic trans. I just wanted to tell you how great of a job you did. I don't know of a thing i would change! Look forward to watching some more of your videos.
Hey Hiram, I'm tearing apart/rebuilding an A4LD model and am using your video as a very useful visual guide. You've given me some extremely helpful tips about not busting stuff and this is the first time ever I've taken apart a transmission. I'll be rewatching this video multiple times. Thanks for the video!
Just commenting to say thanks a lot for this video. Saved my self hundreds of dollars by doing this my self. Super helpful! My spray gear flipped and I had all the symptoms you described.
This video has changed my understanding of automatic transmissions from not knowing much, to absolutely blowing my mind as to the complexity and the engineering that has gone into the development of something that most take for granted every day. You make it look so easy, as obviously you do this stuff all the time. It explains to me that if I have problems with the trany in my truck, take it to someone who knows what their doing! Thank you for the incredible detail in explaining the "what this is and what it does". It does inspire me though to maybe find an old beater, and pull the tranny to tinker with it and see how far I can get! With the quality of the explanations, and a bit of luck, maybe I can! thanks again!
Instead of all this typing go do it
You uploaded this almost a decade ago, but it's still helping people today. Thank you. I hope you're doing well
Well, I just found out that half of the people on the internet are wrong and that the Turbine/Input speed sensor is definitely inside the transmission. Time to sell my Explorer. I have no desire to take this transmission apart far enough to replace a sensor when the transmission isn't even that old. Thanks for the great video. Very helpful.
Men's like this guy are the ones who make America great.... Thanks bro
Videos like these are infinitely better than a forum post or manual for someone with no experience. I was told by a shop locally that any labor to my trans at ~230k miles would warrant a new trans anyways because something is likely to fail. I was able to leave the trans in and rebuild the valve body with a shift kit, adjust bands, and replace servo covers in my driveway in one weekend thanks to you. Still shifting great at 260k!
It's interesting to watch you do your thing. I always bring my transmissions to the professional shops. Thank you for the video posting.
Hi Hiram. You sir are one awesome transmission man. Your video is a delight to watch and I love the way you do teardown. I have never seen anyone better in my 60 years of watching tons of guys turn wrenches and run impacts. Thanks for sharing your skill and knowledge on CZcams. My hat is off to you and all you do!
This was a very informative video. Me and a friend of mine are hopefully about to rebuild the transmission in my 1997 Ford ranger soon. Although we've both been through several other transmissions, this will be a first on one of these.
Great video. have been to school and have a couple transmissions under my belt. an A4LD and a C4. Both easy. Starting on a 4R44E next week. Your video shows that its a little more complicated then the others. But your video shows me the differences and im sure to have zero issues with it. Thanks fior the preview.
Hiram is bad to the bone!
I just removed my 4R55E from my 4.0L exlorer and was hoping to find a good video on youtube and found Hirams video and I am blown away how wonderful he did, nice job!
Thanks so much.
Awesome video Hiram, When it comes to transmissions, You are the man. I've been watching and learning from all of your videos, but i cant find any answers to my trans problem. I have a 96 explorer 4.o with 4r55e transmission. One day the transmission went out as in all the gears that i selected were all forward gears, even park and neutral. The engine was under load all the time. I am a pretty good mechanic when it comes to rebuilding engines, axles, and manual transmissions.In addition to watching you i felt confident in rebuilding this transmission. So i ordered the rebuild kit which included all the gaskets, clutches, bands and o rings and misc. No hard parts. Rebuilt and installed transmission, New fluid(drained old fluid, didn't do complete flush)What i did find during rebuild was that some of the clutches were welded together and the fluid was filthy. Nothing else seems too bad, But i did replace all clutches and seals. Also, I didn't adjust the bands. I just put them back where the were.Now, my main issue. When i select a gear, I get either no response or only reverse. Park is park, reverse is reverse, neutral is neutral drive and overdrive -no response, 2nd -no response, 1st is reverse. I don't know whats going on. I know this is a long story, But if you could point me in the right direction, That would be greatly appreciated.

This is a great vid. Auto transmissions will probably always be a total mystery to me. But its cool to see someone tear it down like its nothing!
I rarely subscribe to you tube channels, but I am watching a real expert. Hiram definitely knows his shit, Great video done really well.
Most educational video on this transmission I've found so far. Thanks very much for showing
Thank you Hiram. I need to get all the information I can on this transmission to help me with my retirement project.
Thank you for this video and your time. A mechanic put my torque converter in wrong and stripped the part that has the notches. Thanks to this I know it's the inner gear and I can replace it myself saving me a lot of money. Thanks very much!!
Just started disassembling my 4r44e glad this video exists!
Can I put a 5R55E/ or or a 3.0 v-6 trans in place where a 4R44E was? , whats the draw-back? really appreciate your teaching! I know you tell us a lot, in the future can you make a lot more comments like that; {not you though I notice an increasing trend of other guys} on you tube not showing the actual performance of operations
Decades of experience distilled into 50 minutes.
Great video,very cool to see how they work thanks
This Dude rules!!! Learned a lot from this vidio (4R75e vid) and its going too save me a grip of cash! Thank you Mr.Gutierrez!
Thanks much for this video. I'm rebuilding an A4LD on a 1990 2.3L Mustang. Your video really helped me understand how everything goes together. Still learning. The quaility of the video is real good too. Thank you for the explainations too.
You’re a cool dude, man. Much appreciate and enjoy your vids 👍🏼
I appreciate that!
Great video. Thanks for talking me out of doing this myself.
That was one of the best instructional videos I have ever seen. You had that apart in just under 1 hr and you took your time and explained things along the way. I have a pretty high mechanical aptitude my master rebuild kit is on my workbench am going to Napa for the input sensor as well as a neutral safety switch in the morning (most likely will take an Uber it's 426am time to pull this into the shop get ratchets going. Hope you made those follow up vids so I have a clue
I uploaded a full rebuild video about 2 months ago. Browse through the channel videos.
@@AutomaticTransmission I ordered the master rebuild kit from global transmission. The only one that contained more was out of stock. As per your advice am waiting on napa to get the input speed sensor in (will be there 8am ). Since I'm having issues starting within park now and then and have to shift the automatic into N tonstart it I'm getting a new neutral safety everything w lose on this thing is from 1999 trans probably that way too.
I sincerely appreciate the work you have put into this video! You just gave me hope! My Ford Ranger has this exact Transmission model, and is about to go out. Thank You!
OK. answer to my own question is seal ring can wear a groove in center support that will keep support and forward clutch cylinder from coming apart new used parts in my case were a most E-bay but look for the right part and price be for you buy even though these parts can be cheap seams like you can always find cheaper and free shipping helps too.
Hiram is bad to the bone for helping us out! Thanks again.
Excellent video. If I were that good at transmissions I'd tear down my 5r55e and rebuild it right now.
Thank you so much for doing this video
👍👍👍
Your a life saver
👍👍👍
I straight want to be this guy. Hyrum is a boss. 👊 I'm rebuilding a 5R55E in my Explorer with no seats but a driver's seat. I just assembled it and had a retaining clip & a bearing left over.. heh. no problem. I'll pull it apart & install the 2 pieces. Got my 99' Explorer for 300$ cause of a broken reverse band. Thing is immaculate otherwise. nice video.
Hiram - Thank you for all your hard work and the informative video.
Always learn something when I watch your videos...You do a terrific job!
Damn, you're good! Amazing how much stuff can fit in a transmission!!!
Thanks, l enjoy the video where you get the parts,4R55E
Can't wait to get started thanks for the great awesome video keep up the good work
Great presentation Hiram. My 97 Explorer trans crapped out. I had no movement in forward gears. I limped home in 4 WD. My vehicle has 155,000 on it. Good engine. I will look for another good explorer. Seems my Overdrive is screwed up as I got a whirring sound as I coasted to a stop.
Excellent video! Wish you could post one of the re-assembly.
If I had to guess... I would say this gentleman has done this before!
Hello, excellent video! Are you going to post an assembly video for the 4R44E?
Have you ever used Knipex Pliers?
I noticed the ones you have would pinch your hands if you slip. The Knipex has the no pinch design. They’re a little more expensive but well worth it.
Their Cobra pliers to replace the ones you were using and a pair of Pliers Wrench also.
I swear you’ll love them!
Hiram please do an assembly video of a 4R55E. Thanks for all you do.
The 5Rs seem to be much harder on the bores than the 4r. To get 5 gears the transmission the trans works the bands more and is double the wear and tear on each upshift cycle.
hi Hiram, I'm thinking about rebuilding my self the 4r44e, I'm pretty confident to the tear down, thanks to your video. do you have a video for the actual rebuilding of it? or are you in the process of making one? thank you very much
i would also love to see a reasembly as i am currently using your Very informative video to save me time and money
Great video so educational. I did my own transmission from this video. Thank you so much sir!!!
THANK YOU FOR MAKING THIS VIDEO AND SHARING IT
VALUABLE KNOWLEDGE
48 MINS WENT BY SO FAST KEEP UP THE GREAT ]WORK!
spiderman
Thanks for posting, very informative. Keep posting.
this guy is good, i think. he's dissecting that transmission like he knows what he's doing but even with a how assemble, i think i'd just convert one to a standard lol. i've done that to a couple trucks, with automatic transmission issues. interesting video though.
Buena explicacion y al grano la mejor ke he visto sr hiran
thank you so much for posting, was swapping a motor in a ranger and could not get the transmission up tight.....turns out my dad pulled the input shaft out and put it back in backwards.....ugggg
No thankfully just had to file the teeth on the shaft and one gear, was intimidated by pulling parts out of Tran till I saw this thnks
watching you do this almost makes me think I can take on such a deeply involved task. (no way in hell I would) excellent video and detailed description of that transmission. I was having some trouble with harsh down shifting from 2nd to 1st. I'm going to do the easy simple stuff first and hope for the best. subscribed because I learned a hell of a lot from your video.
First off you are one hell of an instructor. I never rebuilt a transmission until now and I've gotta say it. Where did this technology come from? This was not intended for automotive this had to have come from something far more advanced and developed in the 60's after seeing the valve train and check balls that control things simply by rate of flow and pressure. It's absolutely amazing. 1 question in a ranger 3.0 with 4r44e transm do I need both the internal radiator cooler plus an external radiator cooler? No this is the first time it's been opened ofcourse not, I knew from the start the lines weren't going to survive. Just wanna know if I can bypass or even eliminate the external cooler. It's only 6" H x 11"L x 1/2" W it can't be doing too much but dumping all my damn fluid when I'm aggressive having fun out in the middle of NO STORE FOR MILES!!! ITS ONLY HAPPENED TWICE🙄 . Enough that I now have a spare cooler and 4 gal at the cabin lol
I know this is an older video. It is one of the best tear downs for thsi transmission.
I rebuilt my 4r44e with a heavy duty rebuild kit off ebay. I am pretty sure sure I installed everything to spec, including the band adjustments. I burnt my 3rd gear playing to hard in the mud and over heated my tranny. All the gears worked, but in D, if I gave it much gas it would slip upon 3rd gear.
But now D slips from the get go, as well as R. 1,2 work perfectly. What do you guy's think I did wrong?
You ever find a 4r44E ASSEMBLY Video anywhere?
@@2oswalds Nope! I did my best putting mine back together, and needless to say it's not as easy as reversing this video. I replaced everything and it still does what it did before I rebuilt it. Even though it had obvious burned clutches that I did replace. So it's still parked in my driveway. Also this is one of the hardest transmissions to find anywhere.
@@adew4u2enjoy Was the overdrive sprag good?
@@rcherping8284 honestly i don't know.
hello, very good instructive video , i have the same question as shane are you going to post an assembly video for the 4r44e ?
Excellent Video. Thanks Hiram
very impressive. what would be the best documented resource to help a DIY mechanic go through a 4R44E rebuild? When performing a complete rebuild, is there a recommended parts list/kit? and then I assume other parts upon inspection. I'd like to tackle a rebuild.
Blown Gasket!? Exactly why most gas stations will OVERFILL transmission fluids...All of my fill tubes are now tie down with zip-ties :)
Thank you for your open bright mind.
Watching this 1/27/2020 very well explained and detailed . I lost 3rd and reverse so I'm thinking my solenoids my be bad or I broke a band.
Thanks fo the video great job
Funny "if you miss the part # rewind the video "
Lol
Exact trans in my truck. Excellent video.
Very informative. Thank you.
I could take that apart...No problem...But I would do the Snoopy dance if I could EVER put it back together again : )
Awesome job explaining
Hey Hiram; thank you for your awesome videos and providing such a vast wealth of knowledge to us for free! Your videos are very confidence inspiring to those of us in the learning process.
Have you published an assembly video of a 5R55E or similar? Or any of your viewers; could you possibly answer that for me? Thank you so much for this great service you provide! 👍
yea i would like to see a reassembly on this transmission it be great if you could do a reassembly video and greatly appreciated
Hiram great videos but I was wondering why you wouldn't keep everything in sequence as you remove it, then it's easier to put back together and then you don't end up with extra parts when your done.
can we use large washers& all thread in place of foot press I really like your videos, mine is 00 ford ranger-w-4cyl. no low& rev fluid is bad
Actually when you break it down the speed turbo sensor isn't that hard to get to. I'm breaking down my wife's transmission and the one that came with the truck. The drum is groove like a rotor would be the band is fried and I can see what they mean by when the overdrive goes and flips. I'd send pictures but I don't know if it go through
Mr., Gutierrez have you made a video on how to put the 4r44e back together. thanks
showing how you put this complicated piece of machinery together sure would be nice lol
Thank you Hiram 👍🏻
4r44e isn't a 55, and there are different versions of 44 identified by casting numbers... there was a 5r too. You can't swap between any of them, even the tcm and harness is different
Great video learned a lot is there anyway you could make a video on the assembly of this transmission.Thank you
you're a hard worker, well done...
dam you are the man .. i have a 5r55e the car wont go into drive or reverse i changed the valve body like 2 weeks ago at a mechanic . could it be the reverse servo o rings .. or do you thing its the sprag and planetery .. i love this truck your help is much appreciated peace.
I have a 2003 Ranger 3.O auto.I have a lot of fluid on the bottom of the pan. I had no leaks on the ground though until I raised the front of the truck today to do a routine brake job. I noticed there was a 4in circle of fluid now on the garage floor.
I haven't cleaned anything up to start looking for leaks but I'm betting this is something you know about already LOL.
What should I do now?
There has been some hard shifts at higher RPMs but shifts pretty smooth overall.
I'm currently disabled and this is my main vehicle to get me back and forth to my spine surgeon and physicals therapy....I'm getting ready for another surgery.....already have 12 bolts....3 are 5in....and 2, -9 inch rods. I wouldn't do the brake but I have to due to lack of funds. I have to do the other side of the brake job tomorrow.
I sure hope this isn't something that's showing and exiting transmission. I don't know if I can handle it with no family anymore. Sorry for the fear rant....lol.
Please let me know what I can do to diagnose deeper.
Thanks so much.....I'm so blessed to have found this video!
Thanks a lot Mr. Gutierrez
Me gustaria pedirle un. Favor. Si usted pudiera demostrar como se usa la herramienta " H " para medir la medida de la pompa de la transmisión. Muchas gracias por la demostración de esta transmission.
Thanks for the video, very informative. Do you have a video which shows the assembling of the same. kindly give the link
Just do it in reverse look up some torque specs for the trans
Thank you for sharing this video. I like the fact you explain every part that was in the transmission & what it dose. So I have this same transmission & my overdrive light keeps flash on my dashboard do I have to get a new transmission or is there a sensor I can replace
Hey good evening and you have a great video. Wanted to know if you have one that shows the teardown of the 4r44e valve body? Does it also show the removal of the manual valve? If it doesn't can you please explain how to remove? Thank you for the detailed explanation.
Buenas Noches Hiram Gutierrez, seria tan amable de una versión en español de este video, Mil Gracias.
You make it look easy bro
Great video. Thanks a million
The 4.0 had the XX55E the 3.0 had the 4r44e and 5r44e
great video, i was able to tear down my 5r55e to replace broken reverse band. but now im having issues reassembling, specifically the "tabs" that apply bands on both of the forward drums; they fell out during teardown and i cant figure out how to position them
by tabs i meant band anchor
nevermind i figured it out. lol. but i could use some assistantce with which bolts go where in the valve body since there is 2-3 different lengths of bolts (i didnt realize this until after removing them)
Just Rebuilt a 5r55E. I have no engagement in drive if I shift from N to D. but if I shift form manual 2 to D, I have engagement. Ever seen this before?
Hello I have a 4r44e and initially I had no reverse. Replaced Reverse band and several bearings and upon install I had all forward gears but weak reverse. On the lift it would engage and go into reverse but on the ground it would barely move the truck... Any ideas? I have tore it back down and reinspected and see no issues. Help Please!
Hello Hiram, I am getting ready to rebuilt my transmission 4R44E, I had a problem with reverse and drive not working at all, when I tear-down should I replace overdrive planetary needle ring as you mention including planetary and all band ? Please let me know. Your video is extreamly helpful ! Thanks for your time.
Where can I find your video of how to put it back together
I like this video....thanks Hiriam -- I like how to dismantle the trans into pieces. I have a 2002 B2300 mazda, rear wheel drive, is the concept the same with my transmission? I am being asked to buy a trans overhaul kit 56006L, trans kit 4R44E, 5R44E, 5R55E...
Thanks for this excellent video!
I have a 4R55E in my '96 Explorer. Loss of reverse, unless you really rev ir....won't upshift from 1st till over 3,000 rpm. Going to attempt a rebuild with a new input speed sensor, new clutches & steels, o-rings seals, and gaskets, & was wondering If it's necessary to change all the bushings? Just hoping my rear needle bearing, and sprags are ok. Also putting in a shift kit.
I have a 1999 Ford Ranger XLT 2 wh drive 3.0 L 6 Cyl 2 wh drive, won't go in reverse. I changed the filter and put the pan back on, it was overfull, But now I can not get the dipstick to go back in, I turned it a million times but it won't go in, help any advise will be appreciated
