Is there some kind of fluid i can put in there to help?

All that "trans magic" crap does is make your trans magically disappear. I would take it to a professional.

Valve is sticking, huh. What if the computer is telling it to shift back and forth because of speed sensor, tach sensor, temp sensor??????? Get it checked with a scanner to see what it's being told to do.
A big 10-4 to what Dirk said. Ablsolutly NOTHING but trans fluid. With 1 exception, Lubeguard. Not Lucas, (their eng oil products are good), not transmedic, not barstrans or any others that I have missed.
