I just bought a 98 contour with V6 and auto tranny. When I test drove it there were no problems. Now I'm having shifting problems. It seems to randomly shift gears ,then sometimes it will shift out completely. Sometimes it does this right away, and sometimes it takes a few miles.I made sure the fluid was at the correct level (and it was). The most recent thing I tried was a trick from old cars. I put the gear shifter between 2 and drive. I've only done a 10 mile loop, but there were no problems. Does this sound like a linkage problem or could it still be something like the valvebody in the tranny? Any suggestions would be great.
