    Great product!!
    By  Rodney,  a  Verified Buyer  from  Iowa  on  May 18, 2019
    I have used this product sense 2008, when doing fluid change this past year in a 3500 Dodge 6-speed with lots of hauling miles it still looked like the day I put it in. I believe in Amsoil products, I wouldn't trust any other brands to keep things running longer an being able to perform 100% without worrying about mechanical breakdowns. Original transmission has over 250,000 miles now with no issues. Don't hesitate to buy a great product!
    Bottom Line
    Yes, I would recommend this to a friend.

    Smoother shifts and happy diffs
    By  Jonathan,  a  Verified Buyer  from  New Hampshire  on  March 29, 2019
    I have used this in my transaxles for years, smooth shifting with protection good enough for track duty. Recently added a limited slip diff to my transaxle and it performs beautifully with the amsoil gear lube. I will not run anything else.
    Bottom Line
    Yes, I would recommend this to a friend.

    The ONLY way to go for a NV4500
    By  PeacemakerJack,  a  Verified Buyer  from  Oshkosh, WI  on  March 06, 2019
    The NV4500 is a unique beast. It is a five speed tranny build by New Venture Gear in conjunction with Castrol to meet the ever growing demand for a stout manual overdrive tranny to back up the stronger diesel motors found in modern pickup trucks. A new gear lube was formulated for this specific transmission. I had owned my Chevy for awhile with this tranny in it when the clutch began to fail. After an overhaul, the tranny shop installed conventional manual gear lube. Within three weeks, I couldn't hardly shift the truck into first or reverse and it was even getting hard to get it into second. I did my own research and found out about the special fluid. I immediately checked to see if Amsoil handled a fluid formulated like the Castrol Syntorque designed for the NV4500 and was overjoyed to see that they did. After changing the fluid, I noticed an immediate difference, a great improvement in shift quality throughout the gear range and rpm powerband. Once again Amsoil delivers a great product suited for a specific need. I would highly recommend this product to anyone owning a vehicle equipped with the NV4500. Well done!
    Bottom Line
    Yes, I would recommend this to a friend.

    Chevy 4 speed
    By  Rockcrusher,  a  Verified Buyer  from  CT  on  November 23, 2018
    I used this product in my 1969 427 Camaro. I've have this car for over 20 years and have used the GM trans gear lube and multiple other brands over the years. Nothing have worked better or have even come close. There was a noticeable difference right away. The shifts seems so much smoother and it actually felt like everything was tighter and a lot less slop. I would highly recommend this product. I even used the gear lube in the squeezable pouches.....it made it so much easier and also worked great. Great Idea!! Great Products!!

    Great Product
    By  RG,  a  Verified Buyer  from  Hawaii  on  June 16, 2018
    First time using this product and it is the best product i have used to date. Please note that if you use a pump to install that the bottle opening is bigger so have the appropriate sized pump for that. I onlyhad the normal size at the time so i have to improvise.
    Bottom Line
    Yes, I would recommend this to a friend.

    Great product and great customer service.
    By  Josh,  a  Verified Buyer  from  Magnolia, TX  on  May 02, 2018
    Put 7 quarts in my cummins g56 transmission after reading several good reviews of this fluid and i could not been happier only issue is i should have done it sooner. The truck is quieter and no issues with shifting at all. Dodges atf4 is not what mercedes says is the correct fluid for the transmission as this is one of the easily obtained fluid for consumers in north america to get. I will be swapping this into the axles when the time come for their service as well.
    Bottom Line
    Yes, I would recommend this to a friend.

    Not for high mileage trans
    By  Chris,  a  Verified Buyer  from  Nebraska  on  January 12, 2018
    I've had good luck in the past with this product, but after putting it in my 296k mile trans it is harder to shift and makes more noise. I will have to switch to a synchromesh or try another product.
    Bottom Line
    Yes, I would recommend this to a friend.

    Not impressed
    By  Tundra08,  a  Verified Buyer  from  Alberta  on  November 09, 2017
    Put this in a 07 Pontiac vibe (as recommend on amsoil website), it worked great for about 4000 km but then ran into issues with shifting and gears grinding, switched it out to the severe gear oil and never looked back, way better performance now. Now I am sure this product would work great in other manual transmissions.

    I used this product in my 95 Geo Tracker, it shifts so smooth I can shift without using the clutch. Also the counter shaft bearings quite whining.
