Stock 6r80 needs programming, different wiring, is expensive to buy and is expensive to upgrade. Yes it'll go 8s a handful of times but then it starts slipping and needs a rebuild. My thread asked specific questions about a th400, has nothing to do with the 6r80. So if you want to try to tell me why I should use the 6r80 then find another thread. Thanks...
TH400s are either 7 or 8 bolt cases. You just have to drill the 7th hole if it's a 6 bolt pump. People have gone 4s in the 8th with 7 bolt cases.2. J.W. has the bell you're looking for that bolt's to the factory case. Note: When doing this swap it is preferred that you use the 8 bolt factory 400 case instead of the 6 bolt unit.
Decided to do a 4l80e with the TCI EZ\TCU computer. Also the tci outlaw shifter. Guessing the JW bellhousing will work with the 4l80e just like with the th400 since it's basically the same?
Man I want to swap to an auto soo bad. Maybe some day
Yea, like KenneB said, it's on the pump. All cases are either 6 or 8 bolts pumps, but behind the 6 bolt pumps, theres a 7th unused bolt boss. You can drill the pump and put the 7th in if you're worried about not enough bolts holding the bellhousing. People have gone 8s and make 1000+ whp on 6 bolts.Where exactly are you guys referencing the 8 bolt pattern th400 from. Is it 8 bolts on the pan or 8 bolts on the pump? Don't want to waste money on the wrong one
