Why does my Mitsubishi tranny slip only after driving over 10 miles?
4 Answers
My guess is the hydraulic operating pressures drop when the fluid is warm and thin.
So could a fluid and filter change fix this and do you have to drop the tranny to do it? ('02 ES)
I would try a fluid change to see if it helps but if it does not you may be looking at a rebuild.
Does the filter change require dropping the tranny?
