Once in a rare while when I am at a dead stop and hit the gas moderately, it feels like the tranny slips just a bit, or shudders before it catches. Once it does "catch", it shifts fine, and wont do it again for quite some time. It only does it rarely (read: maybe once a week). I have checked the fluid, and it is full, I have a tranny cooler installed. Is the tranny beginning to show signs of death? Is there anyway besides a rebuild to correct the problem? And, should I do it now, or wait until it goes?
