    Sounds like you have something Going on. Converter is to tight, gearing wrong, motor aint making enough power etc... i know a few people that sixty foot and go fast with a 60e.

    We actually see cars 60 ft worse after a transbrake TH400 swap compared to a footbrake 4L60E. The 3.06 first gear ratio of the 4L60E is far superior over the 2.48 first gear of the TH400. The car will also average around a .1 second slower with a TH400. When you say "PTC" converter, do you actually mean PTC or are you confusing PTC with Protorque?
