AFTER DRIVEN HOME (15-20 MILES)FINE AND 2-HOUR BREAK, MY Lumina-sedan 3.1L V6 AUTO TRANSMISSION, 4T60-E, WOULD NOT ENGAGE/RUN IN DRIVE AND OVERDRIVE POSITIONS, BUT RUN IN REVERSE, 1&2 (FORWARD) POSITIONS!

THE TRAN. FLUID HAS BEEN RECENTLY REPLACED, AT OK LEVEL, AND IN GOOD CONDITION (REDDISH COLOR). THE NEUTRAL SAFETY/START SWITCH ON TRANSMISSION BODY, HAS BEEN INTERMITTENLY MALFUNCTIONING, SO IT IS BY PASSED FOR THE ENGINE IGNITION. YOUR ADVICE WILL BE APPRECIATED1, THANKS.
