My review of a Performabuilt Level 2 Trans.
First off I own a 2005 GTO. Up until a month ago the car was powered by a Heads/cam + 200 shot nitrous LS2. The Performabuilt Trans. was installed in the car spring of 2007 and in August of this year we went 10.41 @132.47 currently the quickest pass by a stock bottom end GTO in the country. A few weeks ago we decided to put in a much larger power plant so at this time the transmission was pulled out. I decided to have Chance transmissions (converters) go through the Trans. and freshen it up. Well when it was pulled apart Flip gave me a call and said man this thing looks amazing are you sure you have 40k+ miles on it and 200+ nitrous passes like you stated when you dropped it off. I said yes sir this is correct. Needless to say the transmission was flawless inside and in perfect working order. the 3-4 clutches looked brand new.. Awesome news..
So we put the new engine in and reinstalled the transmission backed by a 4k stall FTI converter, GForce CF driveshaft and all new GForce rearend components. The engine is a 416in LS3 12.5:1 compression on 2 stages of Nitrous Outlet Direct Port and plate. Went to SNL Performance for a tune and to get some hard dyno numbers.. Direct Port only the car made 756hp & 888tq. On the plate only the car made 714hp & 841tq. 18 pulls total were made on the dyno without one mechanical issue. We tried to fire both kits together but the car kept trying to lift itself off the dyno so we could not get any hard numbers all out..
So at the end of the day I am really impressed by the piece Frank over at performabuilt sent me 2 1/2 years ago and it has held up to some serious abuse without issue.
I would highly recommend them to anyone looking for a good high quality transmission..

My level 3 Performabuilt unit (4L60E) has yet to skip a beat as well. Very happy with it! I keep the temps down (trans cooler) and the fluid/filter fresh and this thing rocks on.
