My 2004 saturn ion is really giving me fits. The engine and everything else rus perfect but attempting to put it in gear is becoming more of a challenge every day. 1st thru 4th gear it takes a lot of force (met with a lot of resistance). When I bought the car with 106,000 miles it had the same problem and I treated her to amsoil atf fluid which made everything better. She started acting up again about 10,000 miles ago and I changed the fluid agin which did not really help. I am hoping that a fluid change will do the trick again, but I am also realistic that it may be a real problem. Please suggest fluids that I should try before I dive in deeper.
