Best Transmission Fluid around!

Would Recommend

2004 Toyota Camry, 2007 Hyundai Entourage, 2016 Honda Pilot, 2016 Hyundai Elantra GT. I've used this stuff on all my cars for years and always had excellent results. Never had a transmission problem or failure. Thanks Valvoline!

Cheaper than at auto parts stores!!

Would Recommend

Great Automatic Transmission Fluid. Synthetic, lasts, and has a great additives package for a variety of applications. BITOG forum and other log splitter forums recommended this instead of hydraulic fluid due to outstanding cold flow characteristics, so I'm using it for my log splitter to help with cold flow in very cold winter weather.

Works great.

Would Recommend

Have done double drain and fills on 2013 Hyundai Elantra and 2015 Santa Fe at 80k miles. Both shift smooth and flawless. Drain and filled Elantra again at 120k. Fluid looked clean with no burnt odor Gonna use it on my 2011 Camry with 72 k miles. I think it holds up better than OEM fluid

Great fluid, works fine in every automatic vehicle I own

Would Recommend

I own a '03 Hyundai Elantra, '07 Ford Five Hundred, and a '07 Mazda CX7. All 3 vehicles claim the transmission is "Lubed for life", I choose not to adhere to that kind of neglect. I do a drain and fill of the transmission case on each vehicle when I change the engine oil. I'm able to drain 3-3.5 quarts of transmission fluid out of each of them, so it ends up being about 3 quarts of fresh fluid mixed in with 3 or so quarts of old fluid left in the torque converter. After doing that a few times th...

Excellent ATF for Buick 4T65-E transmission

Would Recommend

My 2001 Century started having hard shifts at around 135k miles. I dropped the pan, replaced the filter, and refilled with about 7 quarts of Valvoline MaxLife ATF. I also added in 11 oz of BG ATC (automatic transmission conditioner). What a difference! My car now shifts smoothly and solidly. Maybe I didn't even need the BG ATC? All I know is it now runs like when it was new!

Superb in the 2015 Hyundai Genesis/Genesis G80 8 Speed Too

Would Recommend

Just following up after completing the fluid exchange in my 2015 Hyundai Genesis. The transmission is the same one in the 2017 to 2021 Genesis G80. This ATF works excellently in this vehicle too. That's 3 different transmissions now and they all shift smoothly with no issues.

Wonderful Elixir for ATF Echanges

Would Recommend

I used this at a Valvoline center in Nashville for transmission fluid exchanges in a 2014 Mazda 6 Grand Touring and a 2013 Mazda CX9 Grand Touring, which require different ATF. The results were superb in both vehicles! Slicker shifting was immediately apparent afterwards. I am so thrilled that I am going to use it in my 2015 Hyundai Genesis 8 speed transmission next.

Drain and fill tranny fluid

Would Recommend

Did a drain and fill tranny fluid on Camry 96000 km with Valvoline Maxlife ATF. The old tranny fluid was black in color. Transmission was less noisy and more smooth after drain and fill.

Stopped transmission leak!

Would Recommend

Found a leaking half-shaft seal on wife's Mazda3. Exchanged 8 quarts Maxlife ATF through transmission cooler line to ensure entire fluid volume would be replaced. I rechecked 3 weeks later and the seal area is dry! Fluid level on dipstick has not dropped. Chalk up another Valvoline Victory!!!!

Used in BMW ZF's 5 speed and 6 speed.

Would Recommend

Works perfect in the ZF transmissions, I have the 6HP19 and I changed the fluid at 220,000 miles, not recommended, but I know it was original because the fluid was as black as engine oil with 10k miles on it, when I changed it, I reset the adaptations, new filter(complete oil pan) and it was shifting nice and sharp, it even felt like a stick car when held in gear, it made the torque converter completely lock up like when it was new.

Great Universal Fluid

Would Recommend

I've been using this for years in my GM's, Honda's, Toyota's, Ford's for both transmission and power steering flushes. It works great! Don't use it for CVT applications though -- that fluid has different requirements.

Great stuff.

Would Recommend

I have been using Maxlife for a while, starting with my 2006 Honda Odyssey. I did a few drain and refills on it, switching from Honda DW1 fluid to Maxlife, and it was in my opinion a superior fluid. Transmission shifted better, and no gunk on the magnet anymore. I had a similar experience with my 2015 Malibu with 90,000 miles using Maxlife in it. Great stuff! I will be using it in my Camaro SS transmission soon.

Excellent ATF!

Would Recommend

I was skeptical using maxlife atf in my nissan titan jatco7at but im very glad i did! Shifts were harsh and inconsistent with the oem nissan matic s and now the shifts are very smooth and predictable. This should be nissans factory fill for there jatco7at transmissions!

Works well in Mercedes 722.6 transmissions

Would Recommend

I've used this in all of my W210 E-Class Mercedes with excellent results. The shifts remain smooth and responsive 142,000 miles and still going strong.

Noticeable difference!!

Would Recommend

Just changed O.E. Fluid on my 14 caddy ATS 50K service. I instantly noticed smoother shifting. Did not flush, just filter and mfg refill.

Works great on 2006 Honda Civic!

Would Recommend

Honda recommends using only Honda branded fluid in their vehicles so I was reluctant to use MaxLife ATF in my civic. After reading the public information sheet and getting a email confirmation from Valvoline, I tried MaxLife AFT in my transmission. The result? Better gas mileage and smooth shifting. My Civic transmission is still going strong after 388,000 miles! I was so impressed with MaxLife ATF I tried it on my 2003 Nissan Xterra with excellent results.

I use it DEXRON VI and MERCON LV transmissions.

Would Recommend

I switched over to Valvoline Maxlife ATF in my Silverado's 6L80E and my wife's 4F27E in a 2010 Focus. Valvoline just blends outstanding products which work just as well or better than OEM.

WORKED GREAT in my TACOMA and Forresters(2)

Would Recommend

flushed out all 12qts at radiator hose on my 2011 Tacoma 4cyl at 70Kmi, worked great , wrote down shift points before fluid change and with new fluid shift point were smoother and at 5mph lower speed, that was 70Kmi ago , plan to change fluid again vehicle is approaching 140kmi old fluid was pretty brown at 70Kmi on 4cyl truck that does not haul any weight , glad I used Maxlife used same Maxlife ATF on Subaru forresters 2005, 2010 , also worked well after 30kmi
