Q: my so pulled out of the school parking lot just fine got home and had no reverse. all other gears appear to work fine. no indication of something going wrong just all of the sudden. sudden loss of reverse with all other gears working fine is usually a malfunction in the rear band or servo. place the shifter in 1 accelerate to around 20 mph and throttle back to idle; if the vehicle just freewheels with no engine compression braking the rear band/servo is the problem. depending on engine size you could have either a 42re or 46re transmission and the od unit can also cause loss of reverse. on some units the rear servo fault can be serviced by removing the pan. loss of reverse with an accompanying loss of 3rd gear is a problem in the front clutch. .
