This bulletin applies to 2015-2019 Chevy Corvette vehicles equipped with an automatic transmission. Some customers may complain that the vehicle will not obtain Park at times.
The condition may be caused by a damaged parking pawl and/or parking pawl actuator. The transmission may have experienced a park engagement while the vehicle was in motion, or the transfer case obtained a neutral state. Attempt to duplicate the no-park condition by operating the shift lever.
The shift lever should move freely through all positions. Check the transfer case for proper operation in each range. Inspect the shift cable system and mounting bracket for any signs of visible damage or being misrouted. If all of these conditions are OK, remove the transmission oil pan and valve body. Remove the park pawl actuator bracket and discard the bolts. Remove the park pawl actuator.
Inspect for damage, bent rod or incomplete travel of the actuator. Inspect the park pawl for damage. If damage is present, replace the park pawl actuator, park pawl, main shaft detente lever hub pin, park pawl actuator bracket, park pawl actuator bracket bolts and output carrier. The transmission should be disassembled and cleaned thoroughly.
