I recently just changed the fluid in my 1999 Dodge Ram 2500 diesel with the NV4500 and have noticed that it does shift a little better since. I drive my truck daily either on the normal roads as well as on the ranch. Being that the fluid for our transmissions are very few and far between, this fluid is cheaper and seems to be doing very well so far. Would definitely recommend this fluid to anybody with the NV4500. Thanks again Amsoil for great products!

My 2010 VW Golf 2.5L Manual Trans was hard shifting. The problem was worse in warmer weather than cold weather. At first, I thought it was a hardware issue. I proceeded to change all the worn-out plastic and rubber bushings on my shifter, shifter bracket, etc... Then I finally changed my manual transmission fluid. It was missing nearly half a liter of Trans fluid! I'm guessing that my petroleum-based Trans fluid had burned off. Big lesson. Check your manual Trans fluid first and go synthetic. It changed the fluid 4 times until the shifter felt better. From now on I'm changing my Trans fluid every 5-10K miles with synthetic.

So far, doing its job.

Cold weather needs oil that flows. Amzoil works for manual transmission.

I use this in my Tacoma and it seems to be working great. Amsoil is the best there is so why use anything else.

I put this in my Tacoma and it's working great. No problem down shifting at all.

My car runs so much better now it’s crazy! I really feel the difference.

After 60,000kms in my Subaru I switched to this oil for my transmission. I instantly noticed smoother shifts and improved fuel economy. Definitely worth it!

Used other brand synthetic MTL shifting was so so. When I switched over to Amsoil MTL. Shifting on my 6spd Nb2 Miata is buttery smooth. Highly recommended for manual trans

Have Nissan frontier with 353000km and been using amsoil lubricants...truck runs like a sewing machine...squeeze packs are amazing!

Used this stuff in my HERO 3 Speed Transfer Case. The bags make it easy to fill with no mess! I'll probably never have to change the fluid again.

I used this lube for my 2020 Subaru Crosstrek. Keeps my car running perfectly. Ordered on Monday, arrived on Tuesday, can't beat it. Amsoil is the best you can get!

Used this in my new tremec tkx and transmission operates smoothly

Nothing but the best for my vehicles. Quality products you can trust & count on.

The lube was easy to pour with no spillage. The lube itself so far is working well and no issues.

OEM oil for my NV4500 transmission is hard to find from the dealers but Amsoil had just what I needed

Made my manual transmission shift smoother

This is the only oil that I run in my atlas transfer case it is easy to handle and with the spout you don’t spill any

Worth the extra money to buy the bags over the bottles in my opinion. My 2020 Tacoma shifts a little nicer now with this product. First spill and fill at 10,000 km.

Feels better than the auto parts store synthetic fluid in the 5-speed transmission in our 2000 Miata. Shifts are smooth and easy.
