My friend has a 96 f250 with a strke and auto. The tranny is actinG crazy. Sometimes it doesn't want shift but is not slipping. He had the tranny looked at and nothing on the inside was hurt the guy put new shift solenoids in it and that didn't fix it. When it does this it sometimes pukes the fluid out so we thought it mitt be getting hot. Put on a mondo tranny cooler and that helped thought it fixed it then it started again. Now we think it could be the tsp. Anybody Had this happen or know how to fix it?

 

Make sure you put in the right fluid, and the level required.
