I'm running Rossler Transmission on mine.Hi wondering where the best place to get a TH 400 trans from? Behind a big block with about 700 horse, good hard shifting, thanks!!
Just like on everything , I'm pretty sure the price has gone up since I bought mine.May i ask what a unit like that costs
the 4th gear is the OD... they're basically the same transmission and equally strong, one has the overdrive and heavier but in stock configuration neither one will be happy behind a healthy BBC making an honest 700+hp without any modification. Shock load is your enemy here. Also, an exploding drum and shrapnel going through the floor board and possibly taking out your go pedal foot is not pretty.Opinions are like A holes but a rebuilt 4L80e is as strong as a th400 plus you get a 4th gear & overdrive. Down side is you have to use a trans controller an possibly a shorter driveshaft.
