TH400's are very stout transmissions and require few mods until the hp gets over about 1000. They are also readily available, have a wealth of parts availability, and can be found pretty much anywhere. They are also very easy to work on, even for someone with little experience. For the cost of a decent rebuild kit, some attention to detail, and a couple of easily done and pretty much free mods, you'll have a trans that will last a long time....
That's good to know. I was curious about what the stock internals would handle. I know they're a stout trans, but just how stout, I don't know.

So are you saying with a good rebuild kit, clutches, etc, I could throw on a manual valve body and let it ride and not have to worry about breaking input/output shafts, drum, etc?

Add in the dual feed mod to the direct clutch and restrict the pump feed. Keep line pressure about 200-225 psi and make sure clearances are correct. It will live a long time.

Guess I'm gonna need to get a book on the TH400 to better familiarize myself.
