Dunno if this will help, but mine did this after an engine cleaning a while back. I reset the computer (Removed Neg. battery cable for 2 min.), left the hood open for a few hours and the problem cleared up. If your tranny fluid is not clear with red tint, a change is probably in order and may help. Lots of posts on this subject lately in the tranny forum.

As a last resort, you might try Lucas oil stabilizer, but if you need this, you probably have bigger problems brewing.
