I have a 92 auto na SC300 and it will soon be boosted. My problem is, from what iv heard, this tranny wont hold much over 300 wheel. I dont plan on crazy amounts of hp but I want an auto tranny that will hold. What are my options? Any help is much appreciated. Thanks!

around 320wrhp at 10.5 - 11psi, never had problems. keep in mind that you should get a big oil tranny cooler for long run.

We've had a tt auto tranny run on a APU MKIV putting out 530 rwhp for almost a year without any issues, ended up converting to a 6spd afterwards but the tranny still worked great. I'd say 400 is easily do-able with a decent sized tranny cooler.

However, I remember SuperRunner was running like 700rwhp through his NA auto transmission.

I believe he said the trick was letting the transmission full engage between shifts and the romp on it.

is the na and tt driveshaft the same length?
