Try watching this:
The video is about tuning clutches but you can see how the belt sticks above the edge of the secondary at idle. You should put your machine in neutral and run it through the rpm range watching how the belt advances. Notice on mine the distance between pulleys does not change.......if you have those crappy stock rubber motor mounts yours will. This screws up how the clutches work together.

Buggyman1... Can you please share a bit more on alternatives to ATF Type F, and how it relates to heat and of better quality fluids?
I have noticed the heat from our T20 on long hot rides. What type of fluid is beneficial in this case?
Also, 1.5 quarts instead of one? I wasn't aware whis can be done. Thanks.Stand for the Flag. Kneel for the Cross.

As for alternatives....anything synthetic.....if it costs $4/qt or less, it is not synthetic.....$8/qt and up it probably is. Type "F" fluid dates back to the 1960's when Borg Warner invented the T-20. That is just what was available then.
If all we needed to worry about was friction/lubrication we would use 80-90 gear oil. ATF cools too! Synthetics hold up to heat better than conventional base oil. All oil expands when heated and too much fluid can expand/foam so if you get fluid coming out of the vent plug that means you got too much oil in there(or just plain old too much heat). Some people have eliminated the stone vent plug and opted for a paper vent filter similar to a car tappet cover......hopefully raised a few inches too for splash effect.
Back in the early 2000's GM had a lot of trouble with the AWD transfer cases and the fact that they constantly shifted wore out the fluid in about 15-20k miles. The fix was a better fluid....and that is what I've been using.
