Anyone know how much hp/tq automatics can handle?

How does the automatic transmission hold up? Anyone out there with high hp/tq autos?

Brey335i · 06-20-2011, 04:45 PM

A lot. I have had no problems yet. 16.5 psi.

Lost Marine is having his worked on... but he has upgraded turbos and 500 whp and wtq

My AT is starting to act up (slips/overrevs) shifting 2-3 on 19 psi with grippy tyres probably pushing about 450 whp.

Thats good to hear. Thanks.. Have cobb tuner and want to upgrade some more, just worried about the tranny.

You won't run into tranny problems. The only ones I've heard of with some issues have either upgraded turbos or nitrous

Jeff@TopGearSolutions · 06-20-2011, 05:10 PM

Nothing to worry until you are breaking the 450WHp+ mark.

500nm max... then the proces of slipping is starting....

see my other posts about the zf specs....

I have the ASR turbo upgrades with an AT tranny. Running around 450rwhp @ 16.5 boost via Procede V5. Haven't felt or heard any problems thus far. Also had my shop guy check the tranny for any bits laying around and found nothing.

Do you have dyno sheets thet I could take a look at? I'm on the RB wait list and those numbers seem to be on par if not superior to those from RB'd cars.

so basically not much point in doing more than fbo and meth unless you have the $$ to do a tranny upgrade?
