I like Hyper Lube as additive for the manuel transmissions We used their products at work in motor gear boxes and tramissions for jitneys-lift trucks and it made the shifting so much smoother when shifting. For an example I had my 62 4sp. gear box about to replace syncros when I dumped the hyper lube in and they got me through until I tore the truck down to restore it. We used to have gearboxes go out during the middle of the season and the first year we made the complete run with out a gear box failure. I think that says some thing about their product.
