Question: What causes a transmission to lose reverse?

If your car changes into reverse but won’t move or won’t shift into reverse at all, inspect for a low transmission fluid level. When your vehicle’s transmission fluid level is low, it causes insufficient lubrication, which leads to overheating of the transmission gears.

How do you fix a transmission that won’t go in reverse?

If your manual transmission won’t shift into reverse, try pumping the clutch a few times to build up pressure. If this doesn’t help, turn off the engine and shift through gears, including into reverse. If you are able to engage reverse this way, you know that the clutch needs attention.

Why will my car go forward but not reverse?

This could likely be due to a faulty computer that controls the transmission, a faulty transmission solenoid, or another issue with your transmission. If there is an issue with your solenoid you could be experiencing slipping gears or a transmission that won’t shift into gear properly at all.
