As part of my engine swap I had some mods done to the transmission and after the transmission was reinstalled there is no reverse. The shop that installed the engine/transmission has done numerous swaps on auto cars with TCI shifters and they are convinced the shift cable is not the issue. Additionally, the back-up lights are always on (I am told even with all cable connections to the transmission disconnected). I would assume these issues are related but I don’t know for sure. Any ideas on what this could be? Does the transmission need to go back to the shop that did the trans mods?
