Upgraded the torque conveter on 4l60e from a Yank ST3000 to a 10" TCI Super Streetfighter 4000 a lot looser stall. Now it takes 5-10miles of highway driving before TCC engages then after about 4miles it disengages for another 5-10miles. I have the tune here. Not sure exactly what PIDs to log if anyone wants a log of it.
