Customer Ratings & Reviews

I have been using this product in the rear end of my 1971 Flextrack Nodwell snow cat for over ten years. It performs well with wet brakes and keeps the gear box well protected and cool.

I use this in all of our manual transmissions and so far I like what see smoother shifts. The guys are very hard on the trucks so I want the best in them.

Use in tractor manual transmission and is awesome. Use also in Case 450 dozer hydraulic transmission and unit has strong pushing torque all day and every day

Was doing a clutch on a Eaton 13 speed and decided to replace the oil not knowing the status of the oil that was in the transmission. Oil looked fine but replaced anyway and so glad I did because it actually shifts so much smoother now. I love amsoil products and they will never let you down!
