I just purchased an 87 Conv. 2.3 Automatic for a gas getter. The Trans was recently totally overhauled and suddenly Reverse decides to go out. No noises no warnings one minute its there the next its not. When I put it into Reverse it does nothing its just like Neutral. Are there any common issues anyone knows about? I mean its not a big deal to replace it but if its a simple fix i'll definitely go for that first. I'm not so familiar with the 4cyl models. Fluid is full by the way. lol
