This trammision fluid drain and fill is supposed to be done every 30,000 miles according to the manual. Until 100,000 I had used the dealership, the transmission was never discussed with me and my lack of knowledge or ignorance led me to believe everything was ok.
When starting the the Hyundai and just starting to get to about 10mph the transmission always felt like it slipped, only on cold starts where the vehicle has sat all day/overnight. I added the Amsoil transmission fluid and now no more slip. Super smooth shifts, I stand behind Amsoil and their line of products.
I drive a 2015 Ram 1500 ST 3.6 V6 with a 8 speed 845RE transmission. And this was my first time using a different brand other than the recommended mopar fluid. And Amsoil came thru again! Shifting is way smoother, transmission handles the steep grades I drive daily high revving for 10 miles of steep grade climbs and my transmission temp stays cool and runs like a champion. No matter if I'm hauling a** in low gears or cruising the highway at +75 mph. My transmission is healthier than ever. I'm ditching the mopar for good. Amsoil gots me as a loyal customer indefinitely
this got rid of the jump and hard shift in my wifes 2016 chevy traverse. we like it.
Bottom Line
Yes, I would recommend this to a friend.

I just started using amsoil in the last couple of months and it is unbelievable . I’ve used the liquid gold for my engine, transmission, differentials, and transfer case. I’ve also used the oil, flush treatment and the gas treatment to clean the fuel injectors. All the different products that I’ve used have worked great so far I am also very happy with the company and how they give you discounts for a nominal membership fee. I recommend Amsoil to everybody.

Amsoil fuel efficient transmission fluid

The oe fuel efficient transmission fluid has totally transformed all my transmissions and others that I have serviced. not only are they smoother but the temps dropped on all and has helped on fuel efficiency by a significant amount. Amsoil products actually do exactly what they say it will do. I'm an Amsoil enthusiasts now!!!
Put this in my 2015 silverado 1500 after having some high trans temps and since I have switched to Amsoil it runs 10-15 degrees cooler than it would have before and I have never had the temperature come up like it did the the original fluid.
Brought the mpg's back up in my wifes traverse and got rid of a hard kick on acceleration. I love it in my 17 chevy duramax 6 speed allison. it gets changed again next week. I have run this in it since its first fluid change and now have 150k on it and it shifts nice and mpg's are not too bad for a huge diesel truck.
Works perfectly in the 8-speed Genesis automatic transmission. Smoother delivery of power on a 110k mile engine. Will buy again for all transmission jobs on my vehicles!
Bottom Line
Yes, I would recommend this to a friend.

Second best ATF in the market(1st being Signature Series)

After 30k miles, Ive drained and filled with OE-Efficient ATF 3 times. Ever since then, I drain and refill once every 15k miles sknce I drive 30k miles annually and do it every end of May(before summer starts) and beginning of November(after summer has passed). I currently have 180k miles. Every drain and fill, fresh fluid always comes out and I barely have any metal pieces on my magnetic drain plug. At this rate, my transmission will last forever. My car never slipped. Changing gears is extremely smooth like butter. I will never use any manufacturer ATF ever.
Bottom Line
Yes, I would recommend this to a friend.

good oil

Recently put a good used transmission in my tundra and used a cheaper ATF (maxxlife) for the first 2-3000 miles along with a Magnefine inline filter and after switching to Amsoil the gear shifts, fluid temperature and cold morning drives have been noticeably improved. When I did the fluid change I cut the Magnefine filter open and the filter was clean and very little metalic buildup on the magnet. I will only use Amsoil products.
Bottom Line
Yes, I would recommend this to a friend.

Great Product

I had to replace my transmission temperature sensor in my 2008 F-350 with the 6.4 liter engine. So I went ahead and replaced the fluid and filter as well while doing so. The product is working great, providing a smooth shifting experience.
i have used several different amsoil products for about 20 years motor oil for motorcycles and pickups
all my vehicles use amsoil products and only amsoil products
any fluid that goes in them is amsoil yes it is a little more expensive than others but as i have learned in life you get what you pay for and amsoil is worth every penny
the people that work there are very polite and helpful if you have questions
never had a problem with amsoil but did have a problem with one delivery
ups notified me a package was not being delivered due to damage i notified amsoil about it and they shipped a replacement package the same day did not wait for the return of damaged package to them
when they received they the damaged package they determined that the damage was caused by mishanding during shipping
very good company and people to deal with
i have recommended them to all my friends
Purchased a 2.5gal jug, plus 2qts. To refill transmission on my 2018 GMC DURAMAX after installing a BANKS Ram Air transmission pan,which calls for a 12 qt refill. Fluid level is spot on and I think the transmission shifts smoother. Will be curious this coming summer camping season when I start towing my RV (6500lb travel trailer) throughout the Southeast where transmission temps reached 188 degrees on several occasions last summer!!!
