Q: I changed the Transmission computer one year ago. All the forward gears work, but the reverse does not. The light Panel even indicates that the car is in reverse gear but the car does not move, it's like the car is in neutral. Any suggestions?
A: I'm going to assume your car is automatic and unless you have not checked the hydraulic fluid in your gear box I'm afraid theres very little you can do other than remove and exchange for new gearbox
