Customer Ratings & Reviews

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.

I did a tranny drain in place back in 2018. I dropped the pan, new filter and ran Mercon V through it with a few drain/fills in a month and a half. Then dropped the pan and cleaned it up and refilled with 2 gallons of Amsoil Tran Fluid. No slipping and excellent shifting in cold temps. I will probably drain it again in a year and perhaps drain the torque converter and due a full fluid change with amsoil. The products all work well. Engine oil, gear lubes, transmission fluids, and gas treatments.

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.

I had a 2007.5 6.7L Ram Diesel with the 68rfe transmission. From what I've seen and heard for years is Ram guys having to replace or rebuild their transmission around the 150,000 mile mark. I regularly changed my fluids and filters with Amsoil products. I sold my truck last month 12/22 after 15yrs and 300,000 miles with the stock transmission still performing well with no slippage. I recently purchased a 17 Ram 2500 with the same transmission and 6.7L diesel engine and have already started changing the fluids over to Amsoil products. Thanks to Amsoil for making great products.

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.

Had this fluid changed for about a month. Can tell my Allison trans is shifting much better so far. I am very happy with the signature engine oil and gear oils I've bought as well. May have to change out my heads soon so I'll know more when I do that.

All I use in everything

Changed the ATF on our 2020 Ford Ranger at 20K miles. Got rid of the dreaded lag downshifting in higher gears that most owners complain about. Upshifts and torque converter lockup is much smoother. Amsoil has the best lubricants on the planet. I have converted all our vehicles to Amsoil products. You get what you pay for!
