Customer Ratings & Reviews

All Amsoil product are the best available, so what is there to say. I used this during a partial upgrade to a 4L60E for a hot-rod Fleetwood build. I suspect this ATF will serve me well for years to come and have no doubt it will keep my transmission operating at peak performance.

I never used this trans fluid in this packaging. I filled my Challenger and this package made it very easy to fill.

I recently changed the transmission fluid and filter, on my wife's car. I'm very pleased so far with how the transmission is shifting. With the extra protection that AMSOIL builds into this fluid, I feel better knowing that the transmission should last well into the future. I would much rather keep the fluid changed with this high quality AMSOIL product, than pay thousands for a transmission replacement! We often drive into the mountains, and need that extra level of protection.

I installed a ZNew steering box in my 05 excursion,,and used this as recomended and def made a differance in my brakeing and easier steering in my Hydroboost system~!!

was having shifting issues with my 2018 chrysler pacifica did not always wants to shift intto 9 th gear had my van back to the dealer with very little results decided to replace the transmission fluid even though the van only has 60,000 miles on it it was best thing I did with the fuel saver fluid the transmission now shifts a lot smoother and now shifts into the 9 th gear I 've been a preferred customer since 2009 and firm believer in Amsoil in all my equipment would highly recommend this transmission fluid

How the product is refined surpasses any transmission fluid sold out there today. Excellent product that will protect your transmission.

The best transmission fluid I have ever used. Can totally tell the difference in how my 97 f350 7.3 drives and shifts. And I have the peace of mind of using amsoil in my truck.

After buying a Porsche 911 with a Tiptronic S transmission I was always underwhelmed that the shifts were too smooth and fluid even under hard acceleration, after talking with some pros I decided the best term is sluggish. The transmission fluid was last changed 24,000 miles ago, so it should have had some life left, but I decide to change it anyway. Rather than do a partial change, I refilled and drained it twice, which would have resulted in the old fluid still the torque converter being less than 25%. All I can say is what a difference !!!! The car feels like a manual under hard acceleration. Each shift at 6500 rpm is sharp and firm, and pushes me back in seat like I always expected. When just cruising things are smooth a quiet, downshifts to pass are crisp with out any lag waiting for the engine to rev up. And when spirited driving on track days, the up shift and down shifts are exactly a the Tiptronic should be, with out hesitation or jerkiness as it was before.

I replaced the OEM GM fluid with the Signature Series fluid and no more shudder, my transmission shifts smoother and runs cooler!!

I have used Amsoil products in several of my vehicles and have NEVER had an issue with performance after installing. Two vehicles had noted over-due transmission fluid changes; one over due by 96k and the other over due by 164k ( Yes, that's right ). After removing the pan, thorough cleaning, filter replacement and at least one additional drain = NO! transmission issues due to the fluid change. Don't let mechanics convince you to never change your fluid, if the transmission is operating normally and you are careful and keep the pan and filter dust and lint free, I am convinced you will have no issues after the fluid change. I have full confidence in Amsoil products. Install the best and expect the best protection, reliability and fuel mileage.

This model has had its share of trans shifting problems. Decided to do a complete tranny flush myself and refill Amsoil. So happy it did. The shifting issues are slowly working they’re way out and this vehicle runs so much better. GM uses, well, I’m not sure what they use, but it does seems to be a bad lubricant. Go Amsoil all the way!!!!!

My transmission started slipping between shifts and was getting worse. The transmission shop said I needed to rebuild the transmission. I did a complete exchange with AMSOIL ATF and I haven't had a problem since. That was 90,000 miles ago!

Didnt want to have to get over priced fluid from the dealer. After the fluid change it seems to me that the clutches hook up better and maybe a little faster then factory fluid!

Works for my VW, Ford diesel truck and my Isuzu Trooper. Can’t beat the Preformance and the convenience of just needing one type of fluid for all my vehicles.

Very fast delivery. Most convenient container that I have ever used... never wasted or spilled a drop.

Easy to use and put in. I seem to gain some fuel mileage. I did this on my 2002&2003 Tahoe. I did change all fluids with Amsoil products.

It’s great AMSOIL pays attention and correctly tells you to use this for your transfer case in a 2002 Ford Explorer rather than gear oil or the same transmission fluid that you use for a pan drop because it is a different fluid. As always great quality.

I would never have believed how good it was until I used it.

I got this for my 98 Honda Accord it had a hard shift of each gear. Sometime when turning I would loose power and it would just start revving up before it would go back into gear. With in 1 day of using AMS transmission fluid the was so much better shifting not even hard and no problem around turns now. Will do another drain in 1 month and put fresh fluid again.

I have heard a whole lot of good about the Amsoil products. my wife has got a Jeep Renegade and it was time to change the transmission fluid so i tried Amsoil Synthetic Transmission fluid And as what i heard it works as advertised, I have noticed more of a snap when shifting into gears, then before. Very good product
