Product Description

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 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 transaxles.

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.

Performance Features

• 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

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).

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).

Smoother shifts and happy diffs

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.

The ONLY way to go for a NV4500

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!

Have been told stories about great quality!

I bought an '09 G37 memorial day weekend 109,000 miles. Changed oils to AMS. in storage for winter. Was told great things about AMS. I will say more next year when I experience the greatness of AMS!

Chevy 4 speed

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!!

Changed out transfer case and transmission out of factory oil at 75,000 miles. Now it is as smooth as the day I drove it off the lot. Great stuff. Would highly recommend. Bought more to put on the shelf for the next change. I won't wait as long to change out next time.

Great Product

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.
