That's what Jody at Dp Tuner said has happened to him before.
Cycle the key and the sol unsticks, life is normal.
Good call Bill
A shot in the dark Greg.
SSA could be stuck on. In D range shifts would be 1 to 2 normal. Then transmission would hold 2 when PCM commands the shift to 3. You shut down. Pressure relieves, SSA unsticks. Normal operation again. Hope that helps. The 4R100 Solenoid pack has been updated since 02.
RacerX can explain it better than I, but basically the solenoid gets stuck (for whatever reason) and wont come unstuck because it keeps commanding 2nd.I don't get it, so how does that unstick the solenoid?
Well said. Shut down (key off) relieves the pressure allowing the solenoid actuator to move. A reboot of the system.RacerX can explain it better than I, but basically the solenoid gets stuck (for whatever reason) and wont come unstuck because it keeps commanding 2nd.
You shut the key off and reset the solenoids, relieve pressure, and they go back to normal and shift normally.
