I posted this in the 360 section but got no response, hopefully Tech Q&A will bear insights.. I just completed an oil change of my car and now it is giving me the red "gearbox" light when put in reverse gear. I get an occasional long "beep" alternating the usual short. The reverse still works fine. All the forward gears also work fine both in standard and race without any warning lights. The only different thing this time (it's been on the lift many times) was raising the back of the car to put the undertray back on. The car is a 360CS. Any ideas?
