I trust AMSOIL over other brands, so that’s why I got this.

The best atf money can buy, and at the cost of a replacement transmission, regular servicing with top quality fluid is cheap insurance. I use this fluid as a WS alternative in my Toyota Tundra and Lexus IS , both transmissions operate better than new

used it in my g56 transmission made a huge difference, shifts way smoother, definitely recommend it

What I have read, it’s a good oil,

Used this transmission fluid to replace all of the factory fluid after using Amsoil transmission flush in a 2.8l 2018 Chevy Colorado diesel at 70k miles. Replaced all the fluid and the transmission filter by draining it from the transmission cooling loop and then removing the pan. The truck shifts better than it did on day one when it was purchased new. Could not be more happy to recommend this product. Only regret is not replacing the fluid right after purchasing the truck new. What a difference. All of the clunking went away and the transmission holds the gears much longer as you let off the accelerator pedal. Usually don't write reviews unless something is really good or really bad. This fluid is really good. Love Amsoil products and their preferred Customer program.

Whenever I change Transmisson fluid I will only use Amsoil.

I highly recommend this ATF fluid! I have a 6T70 transmission which is a sealed unit so you only get so much fluid out doing a single drain and fill. So, I did one drain and fill, added Signature Series ATF fluid, drove it for about 200 miles, and then did another drain and fill and added Signature Series ATF fluid again. I estimated I had about 80%+ new fluid in the transmission by this time. However, I've never felt the transmission shift smoother even with 'off the shelf' fluid. It's definitely worth the price. I will never use anything else ever again!

Excellent product. I have some hesitation during 3rd to 4th gear. I changed my transmission fluid with the signature ATF fluid and shifting is smooth and hesitation went away.

Needed to change the Transmission fluid in my wife's 2020 Suburban. Purchased the 2.5 gallon jug and ended up having around 4 quarts left. So I did a little flush removing the return line from the thermostat and removing another 2 quarts. Fluid went in fine keeps the temps lower then before and SUV's transmission seems super smooth and responsive. Highly recommend.

This was used in my plow truck and it has provided smoother shifting. I generally change fluid annually due to the severe service the truck sees. Transmission has 287K miles and still shifts like new.

This made a world of difference! Drained and swapped out the transmission pan at 100k miles. Filled nearly 6 quarts and now no more slipping and the shifts are really smooth cold and hot.

Replaced fluid in a 09 Ram five speed automatic transmission. Transmission shifted smoothly and averaged 15 degrees Fahrenheit cooler operating temperature. I didn’t expect the cooler operating temperature because the factory fluid is synthetic. More proof of buy the best and get the best results.

Love the ATF , AMSOIL Fluid for my Honda Civic

Works Great quieted down Transmission shifts Great Etc...

Like the title states, yes it's time to do a transmission filter and fluid change, unfortunately Amsoil doesn't have a filter for my Audi. Only Amsoil for my vehicles!

Excellent

Installed this in the 10 speed AT in my 2019 F-150. Shifts nice and smooth, a pleasure to drive.

Have this ATF in both of my vehicles. Shifts very smooth. Also noticed some improvement in MPG

It made a world of difference. Shifts better and seems to stay cooler. Used in my 2007 31 foot, E-450 Class C motorhome Torque shift Transmission

My 2019 GMC Sierra 1500 developed the dreaded 8 speed shudder after a couple years and 23,000 miles. I read the GM bulletin and made an appointment with the dealership. They were out about a month and a half. After more research and watching Don Smith’s video I decided to do a complete fluid and filter change. I asked a coworker about whether AMSOIL was worth the extra money and he said it was all his racing friends used. I decided to bite the bulletin and do a complete Amsoil fluid change, engine oil, rear end, and transmission fluid and filter. Flushing the transmission through the cooler lines was a struggle but well worth it. The truck drives better than new. It is quieter and smoother. My wife noticed it immediately. Very happy with my decision to go with Amsoil.
