AMSOIL Synthetic Synchromesh Transmission Fluid (MTF) is specifically designed for manual transmissions and transaxles with synchromesh systems that require light viscosity, non-extreme pressure fortified oil. It is formulated with advanced additive technology to provide proper friction characteristics for smooth shifting without grinding or bump shifting, while providing the ultimate in gear and bearing protection. MTF provides far better protection in these manual transmissions than motor oils and outperforms AMSOIL Series 3000 Synthetic 5W-30 Heavy Duty Diesel Oil (HDD) in transmission applications.

• The GETRAG is very similar to the NV3500, and as far as I know GM has always used ATF or syncromesh in these transmissions. Syncromesh is a 5W30 synthetic fluid VS the 75W90 fluid. They use it over the thicker gear oil for better cold shifting, and increased oiling when cold or in cold climates.
• 5 Speed (RPO MG5)- Manual Transmission Fluid (GM Part No. 1052931) My guess is that all the five speeds take just ATF, specifically Dextron II. I have no idea what the hell 'Manual Transmission Fluid' is, other than something GM made up with a high price tag and ATF content.

Superior Hot and Cold Temperature Performance
AMSOIL Synthetic Synchromesh Transmission Fluid (MTF) outperforms conventional oils and protects internal components at extreme temperatures from -40°F to 300°F. It controls the thinning effects of mechanical shear for stable viscosity and superior film strength, providing better anti-wear performance than conventional oils.

Customized Additives
AMSOIL Synthetic Synchromesh Transmission Fluid (MTF) contains friction modifiers for superior synchronizer compatibility and smooth shifting. It is non-corrosive to yellow metals, and its outstanding anti-wear properties protect gears and bearings under severe duty. MTF is anti-foam fortified and contains oxidation inhibitors to resist high temperatures, oxidation, acid buildup and varnish deposits.

Applications
AMSOIL Synthetic Synchromesh Transmission Fluid (MTF) is recommended for automotive and light truck applications that require synchromesh transmission fluid. Applications include manual transmissions and transaxles such as New Venture NV T350, NV 1500, NV 3500, NV 3550, NV 5600 and Tremec T-4, T-5, T-18, T-176, T-500 and T-600. Replaces Honda Genuine MTX Fluid for manual transaxles. MTF is an SAE 5W-30, however, it is not for use in engines or wet clutches.
