Valvoline Manual Transmission Gear Oil – Synchromesh (1 quart)



Recommended by MWR for stock to performance street applications. Synchromesh offers excellent shifting performance and great friction protection. If you live in a colder climate you’ll find this oil allows better winter shifting than heavier oils like the MT-90.

Synchromesh Fluid is formulated with high quality paraffinic base stocks, a fluidity modifier, multifunctional performance additives, corrosion inhibitors, a foam suppressor and a shear stable viscosity index improver additive. It provides excellent oxidation stability, low temperature performance, excellent synchronizer performance and compatibility with yellow metals, such as bronze, brass and copper components found in manual transaxles and transmissions.

Custom brew: many people find that blending Redline MT-90 and Synchromesh transmission oils allows them to get the best of both worlds: lightning quick shifting and good cold weather performance (Synchromesh) as well as high load high heat protection (MT-90). Here are our recommendations for a transmission requiring 2.5-3 quarts (all Toyota 1ZZ and 2ZZ original transmissions):

Street only, naturally aspirated – 3 quarts Synchromesh
Street and light track, naturally aspirated – 2 quarts Synchromesh, 1 quart MT-90
Street and track, naturally aspirated and light forced induction- 1 quart Synchromesh, 2 quarts MT-90
High power forced induction on street, all forced induction track cars – 3 quarts MT-90
