Customer Ratings & Reviews

I thought the transaxle was going out on me. I inspected the clutch and it was fine. I switched to a better quality fluid, this stuff, and that did it. I think I was loosing horsepower or gears weren't engaging properly before. What a difference the proper fluid makes! Shifts are crisp, engagement is solid. I was missing out this entire time.

THANK YOU NEEDED GL4

I recently flushed out my transmission and differential and my car feels so light and smooth, the inertia from the driveline feels non existent. So much that I didn't realize I was actually speeding at one point while driving on the highway.

Wish I got to use it had the trans rebuilt by a shop filled and installed trans drive it half a mile trans exploaded cause shop left a old ball from the old bearing that went out and I lost 90 dollars worth of fluid but was great for the half mile

Smooth shifting, quiet running GL 4 full synthetic gear oil, a God send to those requiring GL 4 products.

My wife said she found her Miata 6 speed standard transmission was getting harder to shift. We learned years ago that Amsoil made are Harley Davidson transmissions much easier to shift, so I thought I would change her transmission fluid to Amsoil. Their experts said that they would send me the mix that was perfect for her Miata. Just like the Harleys, within a few miles the transmission became much smoother and downshifting is now a breeze. Since we started using Amsoil in our motorcycles we have done so ever since. Good stuff.

Easy fill bag for transmission

I loved the plastic bag, it allowed me to pour the gear lube into my transmission in a tight spot, fluid quality seemed better than OEM, I noticed my truck ran a little smoother shifting than before

Fantastic gear lube. This is in my 76 Jeep CJ7 T150 tranny. Shifts smooth as 🧈!

Best manual transmission fluid I've used to date. Delivery(with tracking) was extremely detailed.

I want my truck to last for hundreds of thousands of miles, so I exclusively use Amsoil products in my truck's transmission and differentials. I believe that Amsoil is the best in the business, and I trust that my truck will last for many, many miles thanks to Amsoil.

Great product. Using the bag vs bottle made the job a breeze. No transfer hoses or pump needed. Just cut the tip and squeeze the bag. Thanks Amsoil

Out of everything I’ve used for my smart car I’m most happy that they have an alternative to using the manufacturer recommended transmission gear lube. Because amsoil had this option I ended up ordering everything from them. And all in one (one stop shop) for every thing I needed… I’m extremely happy with how everything turned out.. my vehicle runs great on all the fluids I changed with amsoil…

the g35 i picked up a couple years ago was always a bit off when shifting from 1st to 2nd and pretty much every other gear. had to give the transmission a sec to sync up or something between every gear! very annoying.. changed out the fluid to this amsoil mtf.. and hot damn.. i can now quick shift like im used to with my civic! also solved an issue where backing up the car on a hill would burn the clutch everytime?!? i can't believe how awesome this amsoil mtf is.. but thank goodness!!

it's really a great product that I recommend

I am completely satisfied with this product it is high quality great performance and I trust it completely.

Great stuff, all I will use! TKS

This Amsoil Manual Transmission & Transaxle fluid is awesome. I put 2 quarts in my 2005 Toyota MR2 Spyder with factory LSD. The car shifts like a dream. I will definitely use it again. I would highly recommend it!

Seems to be very high-quality oil. The packaging needs to come with a small tube so you can cut the tip off and push the tube onto the end which makes everything a lot easier. I had to make my own.

Absolutely fabulous. Used in my tuned S4 and the shifts seem so much better.
