Run synthetic ATF.  It's chemical properties are such that it will heat up much less, lowering transmission temps considerably and extending transmission life.  Shifts nicer, too.

Allison Transynd full synthetic

TCI Max Shift mineral

Both of these products provide excellent, cost effective service in GM automatics. 

Heat kills automatic transmissions rather quickly.  Ensure longer life from your new HP transmission by installing a good supplemental cooler to augment the factory wet cooler.

It's difficult to know just how much you don't know until you know it.
In other words... if people learn by making mistakes, by now I should know just about everything!!!
