    You need a rebuild... Sorry to break it to you gut there is a drive shell that is real bad about breaking in this trans and when it breaks you will like you said have a strong forward but no reverse.

    Sorry to bring the bad news:doah:

    Just looking at the 700R4 troubleshooting diagnosis section in the factory shop manual, there are a number of things that could be causing this symptom (slipping in reverse or no reverse).
