Not a what have you done, but what have you felt lol. The past week with all the wet roads I have to stay out of the throttle. I've noticed at times it feels like the 4l60e is searching for a gear or lock/unlock the torque converter at lower speeds. Could be something with the trans, not having it tuned after the LS swap, I need to calibrate the pedel (DBW), or maybe the reluctor wheel on the output shaft that I pressed on is working loose. I think if it was the relecutor wheel was loose it would act up more with an erratic speed signal. Hope it's not the trans, kill my budget with tax funds lol. More to come I'm sure.
