400 tranny for 355 chevy

Tranny question

So it would be better to build the TH 350c than. I have a Transmission rebuild kit I bought from Oregon performance transmission that has the steels in the kit also. I also have a transgo reprogramming kit. Would this be a better thing to do, re-build the TH350c?

BLUE82...... you started asking questions within a thread of a different subject. I split off your post to a new thread.

GM used the t-400 behind a 350 chevy small block. They work well.

t-400 for a 355 cid chevy

As Crosley states,the 400 works well,tough trans. If you use the 350c and your not brutal,it will do well also.Much has been posted as to how good a th350 can be.

Now one word of caution. If you use the 350c,and you want lockup to work,do not leave the center seal out of the direct drum[dual feed piston].

This is a failsafe device GM uses for the converter clutch apply valve.
