I got everything put back together and took it for a test drive. MAN what a difference. From the first shift I could feel a difference. The shifts are very fast but not harsh at all. Before if would take a couple of seconds to shift between gears but now it is instant! Whether I am giving it light throttle or WOT, it shifts the same with no harshness.

I had read where a few people said they didn't notice any difference and others said it really worked. Well for me, this is now how the truck should have been from the factory. It just works and work right!

If your transmission is stock and slow to shift between gears, this is WELL worth every penny.

Oh and I got it from Riffraff.
