Im not a tranny expert so maybe you guys can direct me. Its for my 99 Durango. She has 135,000 miles on her. Runs perfect. The tranny is starting to act funny. It will want to windout higher than normal from 2 to 3rd gear going easy on the throttle. It will go up to 2400 RPM before she shifts. The disturbing part is once in a while going from 2nd to 3rd you will feel the trans slip totally and she will free rev for a couple of seconds. This has only happened about 3 times on me the past month.

I have never changed the fluid. Would a simple filter and fluid change help or am I dreaming and my tranny is in need of major repair. Would going to ford type F do anything?
