changed and fluid with the Lucas trans fix lube, while changing my trans cooler. The Lucas fluid seems to be working great. It's a little thicker than normal aft, but it stopped a minor leak I had behind the main seal, and it really smoothed out the shift between 1st and 2nd gear... Don't plan to keep it for long. Will be going back to my redline MTL, when I have some time to change the filter too. But the Lucas trans fix was a quick fix and pleasant surprise so far...., picked up couple bottles from HD for less than $20
