If i had a manual 94 bmw 3 series e36 with a chevy 440hp 350 crate engine what is a good replacement tranny, if one is even necesary. i don't know if the stock transmition can support 400 horse. thanks
You need a Chevy trans to fit your engine. Probably best would be a 700R4 due to the overdirve and lock up torque convertor functions but a smaller trans may be required due to space. If smaller is needed you could go with a 200R4 but it probably would not last. A TH350 would be nice but provides only 3 gears. It is strong, small and light.
