Did you check the servo pin travel? Attached is Sonnax's instructions on how to check the travel.

Yeah, you need to measure the servo travel. With a small ruler next to the servo cover, press on it with a crow bar and estimate how much it moves. 1/16" is minimum, 3/16"+ is too much.
How long did the last band last? Does the trans shift OK?

I'm no transmission expert, but if I had to hazard a guess, I'd say that you either have too much band clearance, or there isn't enough pressure on it.
