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

Made a huge difference. When I upgraded the detent springs it dramatically increased the effort to take the car out of a chosen gear. This transmission fluid made a huge difference in changing all the gears. I never had problems before, but the transmission is way smoother now. Highly recommend for Honda manual transmissions.

I have heard alot of goodies things about Amsoil over the years, so I first started using motor oil in my motorcycle very satisfied with it so now just recently did a 6sp transmission swap in my 05 Dodge diesel and put the synchromesh transmission fluid in it. Very pleased with the results.

Great mt fluid for my 10th gen civic. Super fast shipping when needed.

Very impressed with the transmission fluid thus far, transmission seems to be shifting smoothly and is quiter than before. Highly recommend this product

1996 Honda Accord 5sp manual. Have a very slight issue. After installing the recommended AMSOIL manual transmission oil. I find that just after starting the cold vehicle, it’s a bit stiff shifting till things warm up. After A mile or two it becomes buttery smooth.

Been putting this off for months now - had lots of fluids to choose from BUT I’ve heard many good things about AMSoil and have been anxious to try it out - the ordering process was fast&simple, shipping was STOOPID Fast.. I’ve put about 300 miles on the car since changing out my old dirty OEM trans fluid and replaced with AMSoil Synchromesh and things are moving and grooving SUPER smooth. No more ‘notchy’ feeling between gear changes and buttery smooth engagement… Will definitely recommend! Probably going to try the 0W20 Full Synthetic motor oil next! Thanks AMSoil!!!
