I have a 95 5.0 with an automatic tranny. Originally, the transmission was simply revving out between second and third gear for about two seconds, and it was shifting at higher RPM than seemed normal. I recently added Lucas auto tranny additive that was supposed to help the problem. I took it out that night to test it, and now third gear is completely gone. powershifting first and second still works fine. Any ideas on what it might be? I've heard so many different things. I have a tranny i can get for cheap, but i dont want to mess with it if it's a sensor or a vac line or something simple. thanks for the help.
