Ford 4-Speed Toploader Transmission Assembly

[@TiernanDamion]

Hands down the best disassembly and reassembly top loader video on KZbin. Thanks John, we’ll done.

[@bigmike2149]

Just finished my Toploader build. Thanks so much for putting this series together. 👍🏻

[@Gillettesgarage]

Really good job on this video that's worth a subscribe.

[@edoetzel1966]

your 3-4 outer synchro is backwards the three lines always face foward....toward front of case.

[@JohnLatrobe]

Sure, now you tell me! Thanks for pointing it out. Stupid me put it back the way it came out and just assumed it was in the right way to begin with. I’m sure the Ford engineers had a reason for it to be oriented one way, but I wonder if it functions differently when flipped around.

[@Thedoug369]

Interestingly enough, being a Ford guy I've never rebuilt a toploader before. I have worked on some Muncies, BWs and a Saginaw or two but never one of these. Seems to me if you can do one, you can do em all. Now, automatic transmissions, that's a whole nother ball o wax! I ain't gonna lie, I wouldn't know what tf to do once I was inside one of those lol.

Muy buen video😊👍👍👍saludos desde Argentina

Thank you for this excellent video. How has the transmission performed since the rebuild? Did you use the brass rings from the kit or your old ones?

[@JohnLatrobe]

@@albuckle7102 The transmission shifts very smoothly. Making sure the shifter is adjusted properly really helps. If you’re referring to the brass synchos then yes I used the new ones.

How did you get the output bearing on? Heat & press ? Or just heat?

[@JohnLatrobe]

I heated just the inner race to around 250 deg F. It slides on the shaft fairly easily but after a few seconds of contact the bearing transfers its heat to the shaft so you have to be quick. I had to gently tap the inner race with a mallet while rotating the shaft to get it fully seated. If I were to do it over I would find a piece of pipe the proper diameter to help press it on.

[@jdrea5165]

@@JohnLatrobe thanks for the quick reply. I’ve seen a another video where the guy heats it and barely gets the bearing in. I am going to press it in.

[@georgejetson6230]

Nice job, as usual, John! Do you still have the original T1-10H?

[@JohnLatrobe]

I’m not sure what that is.

[@georgejetson6230]

@@JohnLatrobe I believe that Ford used the Borg Warner T-10 4-speed tranny in the Mustang up through 1965, since they couldn't produce enough toploaders for production needs. The H ratio would be the one in your car. I am guessing that perhaps it was changed out prior to you getting the car?

[@JohnLatrobe]

My data plate says transmission code 1 which I think is a 3-speed but that was swapped out long ago. The tag on the old toploader case says HEH-BT which is a 1965 Mustang close-ratio. I’m guessing that the engine and transmission were picked up as a “package deal”, miss-matched rods and cracked case included.

[@joed6011]

Hey John have you had any issues with the aluminum main case so far? I got the same Speedmaster/PCE case for my track Falcon and I had a few issues on assembly. Thanks for any info.

[@JohnLatrobe]

I haven’t had any issues so far, but I do remember that I had to remove some slight burrs in the detent bores that were causing the pins to stick.

[@joed6011]

Ok that’s great news! I’m hoping for the same once the cars running. Yes I saw your vid where you had to clean up the cluster pin and detent bores. Great stuff! I had an extremely tight fit for the cluster gear. I had to get clearance by filing the rear cluster pin boss. Another issue is the trunnion bores seem to be too short causing the trunnion to have too much side to side movement. I shimmed them and they’re pretty good now. Thanks for the reply!

[@johncarollo1788]

Hello John. I am working on an article on Toploaders and would like to talk with you. How can I best contact you?

[@kurts7268]

Lmao, he tries to blame the galling on somebody else. @25:30

[@JohnLatrobe]

Well since it was underneath the seal, then yes 👍

[@bigmike2149]

I’m pretty sure he wasn’t the only person that got into that Toploader, considering it is over 50 years old. I’m certain that seal and rear bushing was replaced before.
