Turbo 400 Info

[BadAssGN]

Guys

I need help with my Turbo 400 build.

I'm used to building 13 and 18 speed Roadranger trannys. I can't remember the last time I built an automatic, (probably a TH350 in the 90s)

I'm trying to understand the power path and the Job of the Sprag

I've gone through the core I bought (New rebuild that burned up because he forgot the filter :tongue: )

I see all the frictions burned up but I'm not versed on which drum is which yet.

The Sprag is intact, all the thrusts look fine as do all the bushings.

Any info is much appreciated, I've been searching google but nothing very helpful yet.

Thanks Jake, that one never came up in my search.

Great stuff there, I have to see if I need a new Sprag drum.


I can see where these builds can get expensive when you start buying hard parts.
