Chevrolet Repair Questions? Ask a Mechanic for Answers ASAP
Hello, my name is Bobby. Thank you for the question. Can you tell me what the*****lights are doing? Is the check engine light on? Any other warning lights on the dash?
Thank you. If the vehicle is not going into reverse then you either have a failure in the transmission or in the transfer case. Most of the time it is the transmission. You need to remove the transmission pan and inspect the fluid for metal. If there is metal then the transmission needs to be rebuilt. If it is fine then remove the encoder motor from the transfer case and see if it disengages as it may have seized up. The only other typical issue is with the transfer case itself locking in place internally. When this occurs though it typically makes noise. I hope this helps. If you need further assistance please let me know.
