My 4L60E held up great in stock trim all the way down to 11.3's. My computer logging started to show the 1-2 shift slipping so I had 1 $1,100 race build-up done to it. I left everything computer controlled except for installing a vacuum modulator.
If you have a choice, I'd go with the new 4L65E from GM performance parts. It comes stock with about a 1/3 of the stuff I did in my race build-up. Mark 1974 White Super Duty Trans Am ----------------------------- 1999 Red TA FireHawk #397 2002 Best: 11.68@116 NA (10.7@127 on the Juice!)

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
