My dad has a 89 xj with 220,000 on the original automatic tranny. Recently it started having some problems... to start with, the tranny shop told him mecanicaly its fine.
When he pulls out of his driveway the tranny is fine all the way through the gears. At about cruising speed (around 40ish) it seems like the tranny is searching for the right gear. It will down shift from drive to 3rd and back again over and over.
After the engin reaches operating temp. he parks it for 10 minutes or so, get back in it and she wont miss a beat. He was told that it might be the tps or the module on the tranny, anyone have any ideas before he start replacing parts? Thanks guys.
