42RE Rebuild Part 2, The Valvebody
Vložit

- In part 2, i overhaul the valvebody, showing an update with a boost plate and replacing the 3-4 accumulator spring and making sure all valves move free. Good news, i got my hands on the big spring that is in the overdrive section so i will be showing that in next weeks video. Thanks for watching, hope everyone is enjoying the series
Been a mechanic most of my life, but have never rebuilt an auto. I have a 44RE and for a while has shown it’s age. Recently I had one of the solenoids replaced. The one that controls shifts from 1st to 2nd, if my terminology is correct. The other day things went bad. It’s would rev up a little to much in first and not shift. Got it to shift by switching shifter positions. Then I experienced slipping. Now it has a real bad whining/squealing while parked in R N D 2 1. Increasing the revs in the respected gear, it kind of goes away, and makes what sounds like a hydraulic bypassing type sound. Like a power steering pump bypassing. I remembered days before experiencing a pulsing in acceleration whiling backing into driveway. Thanks for your video. I may attempt to rebuild it for the experience.
sounds like your filter is clogging up
Thank you so much for sharing your knowledge and experience very helpful.
Thanks for watching
A great thank you for your videos, Gary, I've seen them all that have to do with this transmission. I definitely will use these videos to fix my 42RE transmission, I have the same issue with my transmission. If you have any of your videos up for sale, please let me know so I can buy them to have them as reference. Thank you again for your expertise. God bless you.
thank for little steel checkball locations
Good job Gary, keep up the great work you do
Thanks for Sharing
What is the block you used to sand the valve body mating surfaces? And what grit?
Looked like a honing stone probably medium/fine
There is a steel check ball in the transfer plate lower side only after 96
thank you so much. from Germany Berlin
Thanks for watching

Hi, I have a question, I like your videos and I have a situation with my Cherokee Laredo 99 4x4, the transmission was acting erratic , changing from 1st to 4th and so on, I changed the oil, I changed the filter, for about 10 minutes it was working again , then it stayed in Neutral, I turned it off, started again , drove for 2 minutes and it went back to neutral, I did the same thing a couple of times and it kept on going back to neutral, I’m not sure what else to try, can you help me , any idea why that would be?
Muchas grasias Gary por tu vídeo de como desarmar y como armar el cuerpo de valvulas yo pude aserle una compstura ami camioneta de lo mismo grasias
Thank you!
But you must be more clean after drill.(for table)
Great video series. Accumulating parts to retro fit a 2000 46re to 1999 model version. have comb, shield, reverse adapter by sonnax, overdrive and harness but read only one place the block needs changed as well, is this the case? the solenoid clips in with the shield on the 2000 and inside the block on a 1999 model correct? will the clip work on the inside of a 2000 for the 1999 solenoid? or do i need a 1999 block as well? Thanks again for taking the time to video, definitely increases build time and complexity.
I believe the block is all the same
I rebuild mine I still have the same problem after warmed up it won't move cold drives fine please help
Gary, what's your opinion on drilling the valve body so trans fluid pumps while in Park instead of just in Neutral? I see people recommend it but not sure if it's a good idea.
I have never done that, where did you see this?
Bien excelente Gary
cuanto torque le aplica ?
saludos
Do you have a video of how to assemble the overdrive unit and replacement of circlips. My 42re has lost 4th gear and o/d everything else is Ok. Your videos are excellent but have skipped this repair, ie compressing the spring etc
The large spring is just in a housing, i never take it apart unless it is damaged. Do you have any codes present, do you know if 4th gear is being commanded?
@@GaryFerraro The 1st,2nd, 3rd and reverse shifts work fine however no 4th gear or reverse.
when the pan was removed to determine the fault, a segment of snap ring was found in the bottom of the pan, leading me to believe that a snap ring may have broken and become detached from inside the overdrive unit, The question regarding the spring was that if this snap ring needs to be replaced, then the 800+ lb spring tension problem will need to be addressed. Thanks for your prompt reply.
Not much good information out here in South Australia
@@lloydclonan2599 on the rebuild video, i should show lining up the parts with a shaft and using a press to compress the spring to install the snap ring
@@GaryFerraro That would have made the video series complete, never mind.
Thanks for putting up the videos Gary, very informative, I think I can now confidently carry out the required repairs on my 42re. Wife wants her car back.[2002 Grand Cherokee Laredo]
Keep up the good work.
Sir can i ask somthing i found checkballs weth spring in to the oil pan i dont now where is that came from can i know wheres that location attach?
I need to rebuild mine and I got a quote here in L.A. for $1900, does that sound right?
I'm mechanically inclined and ingest as much info as I can before attempting a job - do to think this is something I can do myself?
Yes, that price is ok
Best regards, I repaired an a518 transmission, the one that comes with only two solenoids. Overdrive and lockup. I completely repaired it, cleaned the valve body. The problem that I have is that it changes from 1a. to 2a. and 2a. to 3a. At very high revs, the engine has to pass 3,000 rpm for the transmission to shift. I have not been able to find the problem, I have lowered the transmission 4 times and I can't find anything that is wrong. any suggestion
Check the throttle cable adjustment and make sure it is not sticking, make sure it is returning, if hanging up may shift late like it's in kickdown
@@GaryFerraro Thanks for answering, I already checked the cable and it's working fine, I also think that cable only works for upshifts, that is, 4th gear. to 3a. 3a. to 2a. and 2a. to 1a., or am I wrong?
Hello everyone, I'm from Europe and I don't understand the size of the hole in the plate at 2:15. I understood that it has 48000 and must be expanded to 69000, but I do not know this unit of measure
if someone can explain to me what 48000 means (inch millimeters????) I would be grateful
that would be thousands of an inch something like .069
@@GaryFerraro Thanks for the reply. Your clip was very helpful
Gary great videos. I am rebuilding a 44re and there us no springs for the plastic accumulator. I heard that it can be ran without them. All other springs are present. I am nearly done and looked everywhere in town yesterday but Noone had them. Online it just shows updated aluminum or rubberized piston but no springs. Can I run it
Wow, never really seen with out springs, was this overhauled before?
@@GaryFerraro yes I believe so. There is chalk writing on the main shaft drum that says A-500. So I figured it broke and they had it overhauled. I called summit racing and they have the lower spring. Which I am sure it had the lower spring and I am thinking when 1 of my boys used my magnetic flashlight it may have caught on and got lost. But whatever happened is crazy, I use small zip lock baggies and write on them where the bolts go and different pieces. It's highly unusual for me to lose a part. However I have taken to long doing this with work and life. But I am nearly done and I didn't know there was a top spring until I seen you put 1 in in video. I looked up part images and it shows top spring (valve body side) I guess it's actually the bottom.
@@GaryFerraro sorry for such a long reply. But do you think just having the 1 spring will run ok( transmission side) I was told that a shift kit could be the reason for springs missing. And I noticed the 1 separator plate looks different than the 1 in your video. Simply because of the little tab that sticks out from the valve body
@@GaryFerraro thanks for replying, I hope I haven't taken up to much of your time
@@iamjustadad6951 very well could be, i never used a shift kit in one of these units, i have seen them with one spring in the past
I need the round 3 pin canastier sensor instead of the transducer I have a 95 4x4 larado I cant find one . do you know where to get one or can it be upgraded to the transducer?
You can up grade but you of course will have to change the internal harness. Where are you located?
@@GaryFerraro Hillsboro TN
I finally found one online so I won't have to change anything thank you for your time.
@@stephaniefults1279 Ok, glad you found, Greetings from New York.
Sir I have a 4l60e trans It newly rebuild for some reason its throwing out oil of dip stick can u tell y tht happens
Could either be getting to hot or possible the vent is clogged
@@GaryFerraro thnxx alot sir for ur rply
How do you test the solenoids to make sure they are good?
all you could really do is ohm them, that will check them electrically but can't really check to see if they are mechanically bad, i always change them
@@GaryFerraro Thanks and keep up the great work. We really appreciate it!
What rebuild kit do you use?
TransTec kits

What is the block you used to sand the valve body mating surfaces? And what grit?
It's probably a whetstone, I've used fine sanding sponges from harbor freight, just whatever you use coat the sanding surface with wd40 first and don't use too much pressure, keep it flat and even
