It has taken me a long time to figure out why I can not select reverse but here's the problem. With the back cover off of the gearbox, I can select reverse without a problem. Put the cover on with the spring mechanism to prevent selecting reverse by mistake and I can still select reverse without a problem. As soon as I start driving the car, reverse becomes inoperable. As I said, it took me a while to figure out why but I have found that when I take the cover off again, the spring mechanism has filled with trans fluid and "hydro locks" so that it won't move enough to allow the finger to select reverse. I thought I might have solved the problem with a part that has a small hole to allow the fluid to escape but it is on the end where the finger contacts it and apparently does not allow the fluid out.
Anyone else have this problem & more importantly, the solution to said problem?
