How do I know if it's going bad? I know they all are firm on 1-2-3 shifts. When mine goes into 4th, it's kind of hard to describe but it you can feel it "slide" into 4th. Kind of feels like an old Chrysler Torqueflite shift. Had the fluid flushed (149K). Trans shop thinks I need a rebuild but I think I will run it until it stops working. I guess I need to go try some other 1st gens on the sale lots and compare 'feel"?
