Since the on-set of problem was sudden, I suspected reverse solenoid in transmission is defective or not getting a signal to acctuate-- anyway to test?
Car has a tach & I read the tach speed @ 1200 rpm running- cold- that dropped to 1000 when (D) drive was engaged-- but tach does the same thing-- 1200 drops to 1000 when (R) reverse is engaged.
Is this a result of the reverse solenoid engaging or is the ECM or CPU reducing the rpm?
Is the park / neutral switch in the electrical circuit for the reverse solenoid? Car was towed with-in the last 60 days, ignition coil, & the wrecker operator was "rough" when he manually tripped the shift lock - I witnessed, but the car didn't show any immediate effects. Could this have an effect? The shift / lock control switch is still operating, car will start in park & neutral only.
ANY IDEAS FROM ANYONE? LARRY MO
have the same problem?
