AMSOIL Transmission fluid recommendations for Cars and Light Duty Trucks


AMSOIL Synthetic Manual Transmission and Transaxle Gear Lube (MTG) is a premium blend of the finest synthetic base oils and advanced, high-performance additives. It is formulated specifically for maximum protection in the most demanding manual transmission and transaxle applications where an extreme pressure GL-4 gear lube is specified, including those where high horsepower/high torque engines and towing or heavy loads increase transmission stress.

AMSOIL MTG helps prevent the thinning effects of mechanical shear. It is formulated to maintain its viscosity and superior film strength for consistent, long-lasting wear protection. AMSOIL Synthetic Manual Transmission & Transaxle Gear Lube excels in hot and cold temperature extremes that exceed the limits of conventional mineral oils. It protects against rust, keeps seals soft for long life, and is compatible with brass synchros for smooth synchromesh shift quality.

Ideal for NV-4500 Transmissions

AMSOIL Synthetic Manual Transmission & Transaxle Gear Lube is a thermally stable, extreme pressure formulation that resists heat, oxidation, acid build-up and varnish. It is the ideal gear lube for high temperature applications, including the New Venture NV-4500 transmission, which retains heat due to its cast iron housing and is often subjected to heavy loads and high torque from turbo-diesel engines.

AMSOIL MTG is the replacement fluid for GM part #12346190 and Chrysler part #4874459 (Chrysler specification #MS-9070).

Ideal for Muscle Car Transmissions

The extreme-pressure design of MTG reduces friction, heat and wear. It withstands the high horsepower and quick shifts common to muscle cars equipped with large-displacement engines.

Ideal for Front-Wheel Drive Transaxles

The advanced synthetic formulation provides superior protection for gears and bearings in front wheel drive transaxles.

Excellent for Service Centers AMSOIL Synthetic Manual Transmission & Transaxle Gear Lube is a versatile transmission and transaxle lubricant. It reduces inventory needs, is readily available and is cost-effective compared to vehicle OEM-branded products.

Performance Features


Recommended for synchronized manual transmissions and transaxles that require 75W-85, 75W-90 or 80W-90 viscosities and any of the following performance specifications: API GL-4 and MT-1, ZF TE-ML 02B, 16A, 17A and 19A, Chrysler MS-9070, MAN 341 ML. Recommended for use in NV 4500 transmissions, and replaces GM part #12346190 and Chrysler part #4874459.

Meets GL-4 performance specifications required by some models of Acura, Hyundai, Infiniti, Kia, Land Rover, Lexus, Mazda, Mitsubishi, Nissan, Subaru, Suzuki, Toyota, Volkswagen, Hino Mitsubishi-Fuso, and Zetor.

Ideal for muscle car transmissions such as Muncie, Borg Warner, Saginaw, Ford Toploader, Dearborn and New Process. Also recommended for Gear Vendors Gear Splitters.

Service Life

Under normal operating conditions AMSOIL MTG will 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).
