The fluid level is always at the high mark. How can this be??? [/quote
Sounds like it is overfilled. Engine running, shift to drive & reverse pausing for a while in each gear. place in park. Fluid level should be at lower end of cold mark. Drive rig & get trans up to temp & recheck. If you can hold the dipstick in your hand it the level shouldn't be in the hot range. Hot level is burn your hands hot.
