@@mountainsgarage ive got a couple questions for you bud. 1. Before installing the pump I gave the output shaft a spin, it moves but it definitely isnt silky smooth. It takes sone umph to get it all moving. Should it be slick like spining a crank in bearings in a block? 2. I dont plan to use the Speedo cable, I saw the core plug for that. I also dont plan to run a kick down and just manually shift it, I can just remove the solinoid and the connector plug right? Or is anything else needed? Lastly is there anything I need to check with the pump out and the new ptc convertor? Or just lube up, install and check that the pump gears engage the comverter and turn the pump? Im getting the new guy jitters but so far everything went together decent, all the drum seals suck for a newbie and not cutting them.

@mountainsgarage 3 жыл бұрын

@@shocker998md3 The tailshaft might turn easier one way than the other. If you got the center support bolt in and the snap ring and it still turns, it’s probably fine. I usually try the hub of the converter through the pump bushing if it’s apart but it’s never a fitment issue, just lube it up and put it in. No need to be nervous, you know how to fix it!

@MountainGarage Just subscribed thank you for sharing this information. I finished a th400 build for my Cadillac engine. It was the first time I ever done one. Is their a fix for the front pump 6Oclock bolt hole? I think I stripped it. Anyway, my torque wrench never clicked and the bolt won't tighten. It leaks. After I installed a Hughes stall it leaks a lot more. I do have a spare but its a 72 case from a Pontiac Wagon. I just don't want rebuild it again. But my gut tells me I will.

@mrblanche Жыл бұрын

The metric thing is easy to explain. In the late 70's, GM announced that they were shifting to metric fasteners...sort of. Their wording was that "only new machining will be switched to metric. So, if you were a mechanic working on GM cars, you needed both SAE and metric tools, because when you started working on, oh, say, a front end, you never knew if the part was new or old machining. It was a real pain for at least 5 years, until every part on a new car was new machining and thus metric.

Years ago, I busted a tail housing. I crawled under some old turd at the junk yard and removed the tail housing on some older car (probably a 70s model something or another). It didn't have a driveshaft in it, so that made it a little easier. I didn't know it when removing it, but it wasn't for a normal th400 size yoke. It was a short shaft tail housing, but it was in-between a th400 & th350 size yoke. 400 yoke wouldn't slide in it at all and a 350 was loose. It's the only one I've ever seen like that. I have never found any information about it.

You are on the right track. I would start by going to the TH400 section of the Crankshaft Coalition website and perform the auto shift valve body mods first. A adjustable red stripe modulator turned in a few turns helps as well. Governor springs can adjust WOT shifts.

After diagnosing the problem I blew air into the dip stick to check the that the breather vent isn't blocked in any way. I removed the vent tube and found that the passage way to the breather vent cap doesn't vent. So the tranny is building up pressure and blowing out the fluid through the dip stick tube. I followed all steps when rebuilding and can't figure out what the blocked is caused from. Anyone have any ideas before I pull the tranny from the car and take it apart again. Thanks

If I want to run a slip yoke on a TH400 that was originally in a truck with a bolt-type yoke, do I NEED to find a yoke with the counterbored recess to make sure the yoke has proper engagement? Based on 17:48 , it seems like the regular yoke without the recess is bottoming out against the o-ring ridge on the shaft. I'm wondering how long that yoke would stick out past the tailhousing

does a th400 bell housing bolt up to 5.3?

@mountainsgarage 3 жыл бұрын

Austen Loan Yes but the middle passenger side bolt can’t be used because it doesn’t exist in the block. I install a Helicoil in the vacant hole in the transmission case to mount the dipstick or transmission shield.

What is your favorite pan gasket material for no leaks?

It’s hard to beat dry cork.

I heard you say it’ll work in a Cah, but will it work in a car?

I heard that too and thought the exact same thing !!

Approx. how many miles can you get out of a TH400 from factory in a daily driver before rebuild needed?

@mountainsgarage Жыл бұрын

Hundreds of thousands of miles. It will probably start leaking first.

@@mountainsgarage okay, so 300K is also a possibility? When driven daily and serviced well over time.

Do you offer built transmissions? I’m looking for a built 400 with a brake.

@@mountainsgarage no unfortunately. I’m located in Wisconsin. I do have a guy that can build me a 400 but ‘he don’t do heavily built 400’s often’…… and I don’t really want to pay some of these prices as some shops want. I just want a built 400 that won’t break the bank….I’m not afraid of spending money but I just don’t get a good feeling from a couple places around me. I’ve watched a bunch of your videos and you obviously know your stuff. I did join that DIY th400 page on Facebook today. I’m building a Chevy colorado with a turbo 6.0 in it. I’m expecting 900 or better with the turbo I have. I know nothing about rebuilding transmissions and I have no interest in experimenting either. Just need to find a honest builder or something. Or just a parts list and I’ll just get it done by me. I appreciate any help. I’m just afraid I’ll be taken for a ride at my local shop….. kinda sad isn’t it? Of course I want a trans brake. ATD I think I was set on.

@@daviddenman7479 Well ATD is also in Wisconsin and they build fine transmissions. In my playlist I have a recipe for that power range so you will have an idea what you need.
