Selling my TCI 4000-4400 stall 4L60 lockup converter out of the Camaro. took the car from 12.8 to 11.8 on motor with just the converter swap. It stalled about 4200 behind our motor. Has about 8K miles on it and worked flawless when removed from the car. Converted to a TH-350 and sold the 4L60 so this is no longer needed.
