94 cougar's 4r70w doesnt want to go through all the gears.
I'm asking this for a friend of mine. He told me that his 94 cat will go into first and then only go into OD. He thinks it's an electronic problem.
I think it might be an accumilater or piston problem. Anyone esle know what may cause such a problem? He said other than changing the filter he hasnt touched the tranny.
