Stage 4 TH400

Spragless first and reverse turbo 400. No check balls. Custom separator plate. Verified fixed 200psi line pressure. New bushings and steel trust washers. Machined pistons for 5 clutches and thick steels in each drum.  All new seals, gaskets, and filter.  All stage 4 builds come with a factory deep pan and short threaded dipstick. Output shaft is drilled and tapped for bolt on yoke.  Stage 4 builds also come with additional aftermarket hard parts to reduce the risk of failures throughout the transmission. This includes billet forward and direct retainer plates, billet forward hub as well as a brand new pump assembly with a hardened stator tube. All billet components used in my builds are Coan Engineering pieces.

I have had some people ask about billet direct drums, give me a call if you are interested in going down that route, I can build with billet steel direct drums but it is a substantial cost adder to a build.  Same can be said for billet output shafts, short tails can be updated to billet output shafts but it is a big cost add. 

All transmissions are tested on a run stand to verify line pressure, cooler line pressure, and shift function, transmissions will be drained before pickup. 

Price listed is for transmissions picked up, if you need a trans shipped please call ahead to handle core drop off or core charge as well as freight cost.  Shipping in the midwest is right around $200 usually.  I don't go to a ton of shows but could like arrange meeting for larger group orders. 

All builds must have a buildable core or a $300 core charge will need to be paid at pickup or prior to shipping.
