92 sunbird transmission

92 sunbird transmission will not go in reverse. Have heard that this problem also exists with Corvettes. Is a rebuild necessary? Any linkage to adjust? Goes great in forward.

Thanks

I doubt the corvette problem is related, the 2 transmissions have nothing in common, one's a FWD transaxle and the other a RWD transmission. Regardless, are we talking a manual or automatic here?

Sorry for the confusion. We are talking about auto trans. Owner was told by another Sunbird owner that there was a known problem with this car, but she was unable to get him to be more detailed.

Your car is equipped with a 3T40 transmission.
You may have a low/reverse return spring that has failed or a cut low/reverse piston seal.
Most likely, the transmission will have to be completely disassembled and inspected.
It would be a good idea to replace all the seals and clutches during reassembly (mostly due to age and mileage), but if inspection deems the clutch material OK, I wouldn't replace the clutches.
