Customer Ratings & Reviews

Jeep tranny feel way better, less sticky. Totally worth the investment.

Buena calidad

New TKX transmission used GM synchromesh first couple hundred miles. Switched to Amsoil SM and it made the trans notchy. Switched back to GM and it’s smooth as butter.

Slight improvement on reverse shifting with my jeep JK, gave it 4 stars because I wish Amsoil would package it in their easy pack bag.

I use this for street and track use. It has kept my transmission safe during lengthy track days with extended sessions and minimal cool down. On the road, it offers such smooth shifting.

Have been using this product for many years. Excellent shifting in all weather!

I've had a tremec 5 speed from Silver Sport Transmission in my 68 Dodge Charger R/T for quite some time. I changed the fluid in my trans to Amsoil Synchromesh and the trans shifts very smooth now. A noticeable difference vs. regular oil I had in it before. I am impressed.

Used this product cause my clutch was being rough. 2 days after I put it in my shifts were so smooth

Slight improvement in smoothness of shifts compared to my OEM Honda fluid I had in my 5 Speed civic. Would recommend, staff is very knowledgeable and helpful. When I was looking for more information on this product they were fast to answer and very helpful.

When it cold shifting is amazing , after 2 hours of driving feels like there is no fluid at all

Super fast shipping! Love this stuff for performance quality.

It feels like my shifting is smoother since I've replaced the fluid in my Jeep. I changed the fluid at 36,000 miles.

I use this instead of Honda MTF because it lasts longer between exchanges before shifts become notchy as the oil begins to shear. Even after draining very clear Honda MTF, noticed an immediate improvement in cold performance, both summer and winter. This is on a well worn in Honda gearbox (currently 350,000km = 217,000k miles), 2/3 of those miles with an upgraded engine swap. Amsoil vs Pennzoil vs Honda MTF https://www.bobistheoilguy.com/forums/ubbthreads.php?ubb=showflat&Number=2352617

It fixed my grinding in my transmission for RSX Type S. I don’t know if it’s because of this product or because I took others advice and added more MTF than the manual said but it shifts like butter now.

I could not ask for better fluid for my GM transmission.
