I just changed the switch on my 1985, if you have the 4+3 transmission the switch is located almost behind the shorter gear rod (reverse) on your transmission. Mine was tough, but after getting a small pair of vise grips on it (because I could fit a 7/8 wrench on it) I broke it lose and it basically came out with my fingers. Putting in the new one in I used the 7/8 open end and snugged it in place.
Using an ECU from a manual transmission Corvette in an automatic transmission Corvette is generally not advisable. The ECUs are programmed differently to accommodate the distinct operating characteristics and control strategies of each transmission type. Installing a manual ECU in an automatic vehicle could lead to performance issues, transmission failures, or improper functioning of the vehicle's systems. It's best to use an ECU specifically designed for your Corvette's transmission type.
