strangest problem I've ever seen, HELP!!!! I unbolted my 4L60E slide it back to replace the flexplate, pulled the convertor forward and pushed it back to reseat it didn't want to take a chance it wasn't seated.
Put it back together, drive the car and everything is fine except now the convertor lock up clutch unlocks when coasting, locks back up when you give it light throttle. Always stayed locked before until it went below the commanded speed. Any suggestion? I'm totally confused. Didn't change the tune, no other changes. No codes or pending codes.
It drives me crazy because the convertor is pretty loose so anytime you let off it coasts when you touch the throttle the rpm rises about 200rpm before the lock up clutch engages and brings the rpm down.
