T-400 question
I am swapping my 76 silverado's th350 with a th400 because the th350 is blown I am going to need a yoke but Im not sure where to get it there are some on ebay I was wondering if someone could guide me too finding this. All help appreciated.

I got tired of replacing the TH350 transmissions in my 82 Silverado, and decided after the last TH350 went, it was time for a TH400. Best move I have ever made! Solid shifts, no lag, and I don't thyink I'll wear it out like the TH350's. Now, the "short" length TH400 is actually shorter than the 9" extension housing TH350 transmissions used in most trucks. I did'nt want to swap driveshafts, or have one made; so, I got a "longer" slip yoke to make up for the driveshaft being just a bit short. This yoke can be cut down as needed, but I did'nt do this. I should have as it bottomed out on the speedometer gear in the trans and shifted it's placement. I don't have a speedometer that currently works due to that, but when the weather finally gets decent again I'll shorten the yoke and reset the speedometer gear. I don't remember the part number for the slip yoke; I got it off of E-Bay. One of it's applications was for use with a transfer case, that may help your search.

Also just an opinion it has a cam and is bored over .030 would you go with a stall or not I'm gonna say no because the cam is only slightly bigger than an rv cam. just wondering what your opinion on stall converters are. :thumbup:

If you have a dual converter bolt pattern flexplate,you can substitute the 13'' 400 converter with a 350 12''....that'll give you a few hundred rpm's of stall over the 400 converter.

is it very possible that my torque converter clutches are bad

oh and rick I was checking out your journal :thumbup: for the 32 ford with chevy engine.
