Customer Ratings & Reviews

Bought this for my 06 RSX that was popping out of 3rd gear. Other owners recommended it and it worked like they said it would, smoother shifting and no popping out of gear!

Excellent products always.

Good product

I did my transmission service on my 2005 rsx type s. The oil definitely made my gear shifting smoother and it eliminated my 3rd gear pop out I'd recommend this product to anyone looking to service their transmission.

I've used this oil for twenty years in my 2004 Dodge Ram 2500 six speed transmission. It works well and the transmission is still going strong at 300k miles.

makes the trans feel brand new

This fluid took what felt like I was shifting through marbles with what I'll call 'finicky' downshifting and smoothed things right out. Change it every 30k and things stay nice and smooth.

Los mejores productos como siempre. Envíos rápidos… lo recomiendo 100%

I’ve been using AMSOIL 5W-30 Manual Synchromesh Transmission Fluid, and it has made a noticeable difference in my car’s performance. The fluid provides incredibly smooth shifting, improving the overall driving experience. My gear transitions are now effortless, and I can feel the precision every time I change gears. Highly recommend it for anyone looking to enhance their manual transmission performance!

I can’t believe it worked! Occasionally 3rd gear would lock out or grind in my 8th gen Honda civic Si. After reading multiple forums talking about how well it works I gave it a try. Immediately the problem went away and I have not looked back over the last month! Great product!

My jeep used to sound like an old military jeep when I would shift now it's quiet when shifting

I had a small, annoying issue with my 2013 Honda Civic since I bought it. (Over 5 years) Second gear was often notchy when downshifting from 3-2, especially in winter during cold weather and the first kilometers driven after starting the car. (Full warm I almost never have this issue.) I saw great reviews about the Amsoil MTF for Honda cars and I decided to give it a try. I replaced my MTF about 3 weeks ago and so far this oil seems to have reduced my notchy second gear about 50% when the car is cold so it's pretty nice. The reason I give 4 stars is because it's pretty expensive but otherwise it's a great product.

This MTF was far better than the OEM MTF fluid in my 6 spd manual transmission.

Used it twice now and after swapping from the factory oil, I noticed easier and faster 4x4 shifting! Good stuff!

This manual transmission fluid will immediately improve your shift smoothness, and definitely protect your most important connection to the ground from your vehicle. Can't buy any better at any price.

I used this product on my 8th gen Honda Civic Si. Very smooth shift and happy with this product. Lubs the synchros well.

At 90,000 interval Amzoil synchromesh manual gear oil looks barely touched

Used this in my 2006 Jeep TJ and tranny shifts much smoother. Nothing more to say, Amsoil is the best!

Original owner of 2008 Honda Civic SI and made the change to AMSOIL synthetic at the first oil and filter interval for both engine and transmission. 16 years later and still still a daily driver with zero issues in the power-train. From -40 to +40 centigrade this synthetic oil has been ideal in our harsh conditions. I can confidently recommend this to anyone looking for a superior synthetic lubricant in their motor vehicle.

fixed my 3rd gear pop-out completely
