A very informative and well done video, Terry! Learned more in three videos than I did reading as much information as I could find about this! Thanks!
You bet! Thanks for the kind words! Hope your rebuild goes well.
Thanks for a very informative video. Very interesting and I learned a lot. Thanks
You bet Steven!
Such a great video! I am in the process of rebuilding my '35' (the whole car) but currently on the gearbox. Identical and a perfect tutorial. Thanks so much!
You bet! Glad I could help!
Excellent video on the transmission service. Thank you!
Thank you Mike! Part 4 coming soon....
37 Dodge has almost set up, i need to finish engine rebuild.
Im in California in Los Angeles
County San Gabriel valley and mechanics with anh knowledge have either aged out or passed. I need to connect brake / clutch pedal assembly to tranny
Great job on the video. Tons of time editing and producing this! Much appreciated. Great tip on the oil plug magnet. I'll be doing that.
Thanks Keith. I appreciate your vid's and help in getting this episode produced. Yes, a pile of time in editing, re-takes and voice overs! Lots of film on the cutting room floor. Ha!
What an invaluable video! I am in the process of rebuilding my 37 Transmission Thanks Terry!
You bet Steve! Good luck with your rebuild!
Good job Terry! You certainly have more nerve than I do to tear into a transmission! Looks real good though.
Thanks Wayne! I always have the end of the project in mind when I start one. So with this one, my desire is to make the '37 Coupe a reliable daily driver before next summer. This is the first time I ever took a manual transmission apart and with Keith's Garage channel I had high confidence I'd be able to complete it successfully. Now on to the installation (parts 4 and 5 coming soon)!
@@FlatheadTerry Well you REALLY impressed me by tackling, what is to me, an intimidating job. You really do inspire me with my projects on my ‘50 Ford coupe that was my Dad’s. I really look forward to every video you upload! May God bless you as you make progress with the Plymouth!
these sliding gearboxes were notorious for chipped teeth on the first gear, this was an aberration to not install a synchro on the first gear, they used that setup up to then '70,s.
I had a '64 Valiant with the A903 crashbox, you should understand that the gearbox ended with a chipped 1St gear, I ended by replaced it by a A833 4 speed all syncho gearbox, the best move I've done on that car.
Thank you for the great videos. I watched the disk braking one and these tranny rebuild series!!! Anyway I have been researching different options for my coupe! ...and always wanted more than 3 gears, so I figured a 5 speed from a ranger should be about right!
I don't mean to highjack this thread in anyway, so just a couple of thoughts here should be about enough!
Anyhow, ...in the middle of all these options being researched my crazy voices started coming back and they are saying to put a modern German twin turbo I6 with a nice European 6 speed on the floor!!! in my coupe!!! You know do it once, do it right type of thing, and no I would never want a LS in such a classic car!!! ...but a twin turbo I6!!!! That's not too far away from original!!!
Please talk me out of it!!!
Hi Terry, this is very interesting to me, and topical. Just today I did the same job on an early Ford 3 speed. It's fascinating to see how things are similar but different. Your box looked in great condition until you showed that broken tooth. I'm impressed that you were able to locate the parts to do the rebuild. I tore down a 52 F1 box and it had the loose rollers. I rebuilt it with earlier gears and they use the caged rollers so no dummy countershaft needed. Watch out for a video showing how similar they are. This was an excellent series. Great editing and production. Mart in the UK.
Thanks for the info and kind comments Mart. I really appreciate it. I'm curious to see your video on this subject to see the differences. This is my first time rebuilding a manual transmission and wasn't as difficult as I anticipated. Can't wait to get it back in the coupe!
I really love your videos! Can you remind me what size dowel rod you used for the cluster gear assembly?
Thank you! Glad you can use the video as reference. The dowel is 5/8" diameter. A slight taper at one end is definitely helpful!
I plan to rebuild a 3 speed transmission from a 1953 Dodge B3B pick in a couple of days. Although there are some obvious differences in our transmissions it appears internally the are the same. Thank you for the video as it gives me insight into the project. Meanwhile, the engine is currently at the machine shop and I am waiting for a determination if it can be bored or needs sleeves. Thanks again, I enjoy watching you videos.
Thanks for the kind words Gary. Glad I can help ya out! Best of luck with your rebuild.
Hi, the gears look like the inside of a Early Ford. i put in a new small parts kit, and synchros in a 39 ford trans for my 36 Ford Pickup. Ford used caged rollers for the main shaft and the counter shaft, the loose ones are a bugger to get back together, thanks for the vid!
Thanks for the comments MrBrendog67! That's interesting how Ford used the caged rollers design. My early 40's Harley's employ them on the wheel hubs. They are very handy!!!
Possible to add synchronizing rings on 2nd and 3rd gears?
Hey Ray, 2nd and 3rd already have synchros. None for 1st and reverse.
Are those brake band strong enough to keep the car from rolling back on a hill?
Believe it or not, yes it holds on a hill. I use it all the time. Proper adjustment is key!
Terry are you able to share info on the rear seal you used? Is it a modern neoprene type? Brand and part number? I also need one. Thx.
Hey Keith, I got it from Andy Bernbaum Auto Parts at m.oldmoparts.com/rear-transmission-seal.aspx. I ordered their part number T-115A. It is modern neoprene and has a nice "snug" fit on the brake drum sleeve. I haven't installed the transmission yet do I don't know its effectiveness yet. Hope this helps!
Hey terry. Awesome video. I just resealed a three speed out of a 54 savoy and I’m still getting a leak from the front. Any idea where it’s coming from. Much thanks.
Thanks Vlander! Hmmm...I'm assuming you replaced the front Pinion bearing with a new "sealed" type which in theory should prevent leakage. I see Andy Bernbaum has them. My quick thought would be it leaking from the outer bearing and transmission case. Mine was a very tight fit. (I also assume you're running 90w gear oil and its not over filled. Note that with the Cluster gear so close to the bottom of the case, it can pick up lubrication easily and distribute it when its' slightly under filled as a last resort - depending on how bad the leak is).
Hey terry! I did not replace any bearings, only seals to “fix” the leak. I am going to pull the trans back out this weekend to see where it’s coming from. I didn’t overfill that I’m aware of. I filled until fluid was coming out or the fill hole.
I used 75w/90
@vlander005 ok, yeah its' very difficult to overfill these with these babies! Keep me posted on what you find. Very curious!
Will do. Any chance you know what the flywheel bolt torque is? Six bolts/studs. 5/8 wrench on the nut.
If Your transmission is working perfectly I recommend taking it out cleaning it replacing seals and that’s it .
Great videos! I have a 37 dodge coupe and I see how to drain the transmission fluid but what’s the easiest way to refill it?
There's no easy way to refill it. Back then they had hand pumps with a noozle that fit into the hole. Now a small funnel and a small cup is one way to refill it. Not fun!
@@FlatheadTerry good to know thanks
@@TsavoHwy You can use a large syringe as well. There just isn't much room to work with. Fill it until oil comes out the hole your filling it up with and replace the bolt.
I like to see how you hook the spring on the throw out bering
Hi Terry,
At about 26:50 in the video I see the install of the speedometer gear. What size socket were you using? Asking since I'm trying to get mine out to seal up a leak. Thinking it is larger than a 1" socket.
Hey David, how's it goin'? Unfortunately, I don't recall what size socket I used. I know I would not have much access to it once I reinstalled everything back in the coupe. I don't think it was over 1".
@@FlatheadTerry Thanks for the fast reply! I bought several deep sockets today and it turns out to be a 1 1/16" that fits. I removed the assembly so the pinion seal can be replaced.
@@davidbaures1256 Great! I wasn't close with my guess at what size it was? Dooh!
HELP! How did you remove the 2 pins for the bell housing?
Good question Steve! I did not remove mine so I can't give you experienced advice. I normally apply heat to hard to remove parts with good success!
Your tranny is in INCREABLE condition for 65,000 miles! You could have re-used your cluster gears with NO PROBLEMS , but NOS parts are a miracle! Lester's Gears here in Tulsa, OK on North Lewis Ave. may be a source for rear end parts if you need them. Hold your tongue just right when installing stuff you can't see! The Chrysler Transmission is a full sychomesh and past '38 have vacuum shifters that shift them automatically from second to third, and when back into neutral (you don't need to engage the clutch! ) they'll drop back into first automatically! At least on New Yorkers, as I've driven one! Oh, you were suppose to install new emergency brake lining yourself! ;) On that drum, you are learning to be a MECHANIC sir! You aren't a "parts changer".
Hi terry
I have a 50 Plymouth
I just had the clutch replaced..new ring gear and flywheel resurfaced, and the transmission taken apart as ball bearings were worn (that’s what the mechanic said) otherwise Trany is good condition. New parking brake lining ect. Rear brakes adjusted
Now
Shifting seams a bit stiff white car is not moving abd ur parked, and while backing up in reverse, there is resistance..like there is a brake on?
Machine can’t figure out why this is happening.
Any advice on what should be chased down first?
Thanks for posting
Stan
You should have used gl4 gear oil it's compleatly compatible with gl1 used gearbox just modern and 10 times better for the gears..but never use gl5 it will destroy any bronze or copper parts ..
Thanks for the comment. However, I don't agree with your suggestion. The specs on GL-4 state that its designed for hypoid gears which this gearbox does not contain plus additional additives.. What additional benefits would my transmission gain? I drive it 600 miles a year with an 84 HP motor.
