Hey everyone,
I'm new to the forum, so if this has already been discussed or solved, please send me in the right direction.

I have a 95 GT with auto trans. Just started to act funny when driving at a constant speed, usually between 35-50mph. It almost seems like the transmission doesn't know which gear it wants to be in, as it will go through short periods where it will try to shift up and down on its own. There is no slipping from a stand still and shifts up to this speed are smooth. Fluid and filter were just changed thinking this may solve the problem.

Any help or ideas would be greatly appreciated.
Thanks in advance!

The 'overdrive gear', or your top 'gear' is not a metal gear but a band that eventually wears out. I don't know the actual mechanics behind it, but when the band begins to wear out the tranny will slip in and out of the top overdrive 'gear'. You can prevent the tranny from going into overdrive by pressing the "OD" button next to the shifter. The band is inside the transmission, so it needs to be taken apart to replace it.
