Manual Transmission & Transaxle Gear Lube 75W-90



Towing, heavy hauling and performance driving create shock-loading conditions and elevated heat that threaten the performance and life of manual transmissions and transaxles. Making matters worse, horsepower, torque and towing capacities seem to increase with each new vehicle model year, increasing severity. AMSOIL Synthetic Manual Transmission & Transaxle Gear Lube is specifically formulated to reduce friction and maintain viscosity for long component and fluid life. It is designed to excel in severe-service conditions that exceed the limitations of conventional fluids.

Protects Against Wear & Heat in Severe Applications
Synthetic Manual Transmission & Transaxle Gear Lube is shear-stable and maintains its viscosity despite rigorous mechanical action. It provides a thick lubricating film and contains extreme-pressure additives to protect against wear in severe-service and shock-loading conditions common when towing or hauling. It resists thermal degradation and oxidation for excellent performance in high-temperature applications, such as the New Venture NV-4500 transmission, which retains heat due to its cast-iron housing and is often subject to increased torque from turbodiesel engines.

Quick Shifts & Excellent Protection in Hot Rods and Muscle Cars
Synthetic Manual Transmission Gear Lube's friction-modified formula and excellent cold-flow properties promote smooth, fast engagement of synchronizers and gears. It protects against wear caused by the high-horsepower, large-displacement engines common to hot rods and muscle cars. It is formulated with seal conditioners to reduce leaks.

Promotes Longevity in Front-Wheel-Drive Transaxles
Synthetic Manual Transmission Gear Lube meets 75W/80W-90 viscosity requirements and exceeds API GL-4 performance requirements for many front-wheel-drive vehicles. Its excellent gear protection, extreme-temperature performance and durability promote maximum longevity and reduced maintenance costs.

  • Protects against increased heat and pressure
  • Outstanding cold-flow properties
  • Protects brass synchronizers
  • Friction-modified
  • Excellent seal compatibility
  • Inhibits rust and corrosion
  • Long service life

Applications
Synthetic Manual Transmission & Transaxle Gear Lube is recommended for applications requiring a 75W-85, 75W-90 or 80W-90 viscosity gear oil with any of the listed specifications:

  • API GL-4
  • Chrysler MS-9070
  • ZF TE-ML 02b, 17a
  • MAN 341-Z2 (formerly MAN 341 ML)
  • MB 235.5

Replaces GM part #12346190 and Chrysler part #4874459. Examples of transmissions and transaxles requiring a 75W-90, API GL-4 lubricant include certain models of Hyundai, Infiniti, Kia, Lexus, Mazda, Mitsubishi, Nissan, Suzuki, Toyota, Volkswagen and Hino.

Examples of street rod and muscle car transmissions include Muncie, Borg Warner, Saginaw, Ford Toploader, Dearborn and New Process.

Service Life
Under normal operating conditions AMSOIL Synthetic Manual Transmission & Transaxle Gear Lube last two times longer than conventional petroleum GL-4 gear oils. Where the original equipment manufacturer (OEM) recommends synthetic oils, follow the OEM drain interval (such as NV-4500).

HEALTH & SAFETY
This product is not expected to cause health concerns when used for the intended application and according to the recommendations in the Material Safety Data Sheet (MSDS). An MSDS is available via the Internet at www.amsoil.com or upon request at (715) 392-7101. Keep Out of Reach of Children. Don't pollute.

    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.

    By  jcs757,  a  Verified Buyer  from  Portland, OR  on  December 17, 2018
    This is simply fantastic gear oil for the older spec manual transmissions that require a GL4 spec oil!
    Bottom Line
    Yes, I would recommend this to a friend.
