UPDATE - I tightened up the top mount bolt less than an 1/8th turn, today the gear changes seem less sloppy, 3rd isn't holding as long but may still be holding slightly. I've noticed when going up hill the car doesn't change down gears quite so often either (before the car would change down, pick up speed, then change up, lose a bit of speen and change down again, a lot) I'll be driving for about 1 1/2 hours tonight so I'll have a better idea later. I wanted to eliminate the options one by one so didn't reset the ECU. EDIT - Gear changes are definitely smoother and quicker, 3rd into 4th gear still holds but not as long.
