I did a FAQ search and did not find the information I needed.

1996 Chevy c/k 1500, auto, v8, 350, lwb, 2wd, highway use and a lot of boat tow

In a nutshell, at one hundred fifty thousand miles a year ago my transmission started slipping in reverse, progressed to having to rev the engine in order to get it to catch in reverse and then ultimately lost all reverse. I bit the bullet and spent maybe fourteen hundred to have it rebuilt. It did well for maybe a year. Now, the exact same problem AGAIN. I have noticed it does not have a problem when first started. Once it is warmed, it slips. The transmission shop says it is out of warranty and they are not real sure what may be going on there.

I am very frustrated here. Why am I having this problem again and what should I do????

Thanks for all comments
