First off did you bother changing tranny fluid? Ever? Check and inspect the fluid first. The cheapest thing you can do is change it along with the filter and pray that it solves your problem. Unless you can diagnose you the problem your self I suggest you take it to someone who can. Here are your options. If it doesn't stall in 1st and Reverse then let me know I will get you more diagnostics info.
