In a car’s transmission, the reverse shell, otherwise known as the sun shell, is located inside the transmission. It engages the revolving drum, activating a sun gear of a planetary gear set (also known as an epicyclic gear chain) to achieve reverse, and this sun gear is splined to the shell, which splines either strip completely or partially. One possibility is, because it isn’t switching into reverse or drive, it means one of the gears isn’t completely splining onto either the drive or reserve shaft, as the teeth on the gear might be wearing, or might be falling out of alignment. The linkage between the shifter and the transmission could also be hanging up on something. The linkage is what connects the shifter to the transmission to change the status. The forward gears will probably start losing their grip too if the gear isn’t easily slipping into forward or reverse drive. There are many replacement shells available for that transmission to fix this problem. Another possibility might be a problem in the reverse clutch, in how the gear shifts into reverse, and not a problem with the linkage. Both are internal problems in the transmission of the car, and therefore would need disassembly to either repair, or determine the problem for sure. Before any conclusions are drawn you would need to determine more about the issue, not just that it won’t go easily into either forward or reverse gear.
