Hey there. Since you only seem to have the problem on a hill, then you may be very low on transmission fluid. When the car is put in reverse, it pumps fluid into a large servo to engage the reverse band.

If the fluid level is low, it could be that all it is pumping is foam so the servo is not filling fully and the band does not engage. Check the transmission fluid when the car is in idling and in park on a level surface and top it off if necessary.

If that doesn’t help, your transmission may just be in the early stages of failure. They usually lose reverse before they stop working altogether. A certified technician from YourMechanic can inspect the transmission issue at your car’s location to advise you on proper repairs.
