PRODUCT DESCRIPTION
AMSOIL Synthetic Synchromesh Transmission Fluid (MTF) is a premium quality synthetic lubricant
designed to surpass the most demanding lubrication requirements of manual transmissions and
transaxles where non-extreme pressure fluids are used.

MTF protects gears and bearings in extreme temperatures. It outperforms conventional oils and
delivers outstanding performance from -40°F to 300°F. It maximizes energy efficiency and resists the
effects of heat, oxidation, sludge and varnish deposits.

Unlike its mineral oil counterparts, MTF prevents the thinning effects of mechanical shear for stable
viscosity, superior film strength and anti-wear performance. It protects against rust, keeps seals soft
for long life, and is compatible with brass synchros for smooth synchromesh shift quality.

IDEAL FOR MANY GENERAL MOTORS, CHRYSLER, HONDA and OTHER VEHICLES
AMSOIL Manual Synchromesh Transmission Fluid is a higher quality, lower cost replacement for
multiple vehicle manufacturer branded products. This premium synthetic formulation provides
enhanced anti-wear protection and lasts longer in service. MTF exceeds the performance
requirements of both manual transmissions and transaxles.

EXCELLENT FOR SERVICE CENTERS
AMSOIL Manual Synchromesh Transmission fluid is a versatile transmission lubricant. It reduces
inventory needs, is readily available and is cost effective compared to vehicle manufacturer branded
products.
