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
AMSOIL MTG prevents the thinning effects of mechanical shear. It maintains its viscosity and
superior film strength for consistent, long-lasting wear protection. MTG 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
MTG 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 ultimate protection for gears and bearings in front wheel drive
Excellent for Service Centers
MTG is a versatile transmission and transaxle lubricant. It reduces inventory needs, is readily available and
is cost effective compared to vehicle OEM-branded products.
• Reduces friction, heat and wear
• Superior high temperature stability
• Resists heat, oxidation, acid build-up and varnish
• Lasts two times longer than conventional petroleum oils
• Improves cold weather shifting
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.
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).
