WILL NOT SHIFT INTO REVERSE
There is an interlock that prevents you from shifting into reverse if the car is moving about a certain speed. This is both electric for the sensor and mechanical on the shifter. It is similar to the interlock that prevents you from shifting into gear on an automatic without depressing the brake.
A couple of questions. Does the gear indicator on the dash display all seven gears as you shift into them? If not the maybe you have something as simple as a bad connection. There are error code so I would expect a Check Engine Light (CEL). The replacement of this sensor is straightforward but does require a lot of equipment and time. If you have the equipment to lift the car and look at the sensor it might give you a clue. There are videos on you tube on the entire process.
Here is an AI summary.
Replacing the gear position sensor on a Corvette C7 with the Tremec TR-6070 7-speed manual transmission typically involves removing the driveshaft, disconnecting the sensor wiring, and unbolting the old sensor. Reinstallation is the reverse process, ensuring proper sensor alignment and torque specifications.

Removing the battery cable clears the DTC but does not solve what caused the fault in the first place. Sometimes these are just ghosts but sometimes they come back.One of neighbors read that by disconnecting the negative cable for approxamatly 15 minutes might help. I did that & it worked.
thanks for all your help too
