When I slow down to stop, I feel the tranny go limp (no more engine braking), then it has no torque, forward or back ward, as if it was in neutral mode. If I shut down the engine , wait a minute, and start it up again, the trans works fine, shifts fine, until I slow down again. No codes when shut off. No codes when running in failure condition, either. Seems electrical (controls), not the actual trans. Comments?
