Red Line Synthetic MTL 70W80 GL4 Manual Transmission Gear Oil 1 Quart

Our MTL 70W80 GL-4 Manual Transmission Gear Oil is a popular replacement for and improvement over GM Synchromesh #12345349. Safe for brass synchros, as it lacks the reactive sulfurs found in most GL-5 oils that cause damage resulting in quicker shifts, perfect synchronizer coefficient of friction and eliminates notchy shifting, even when cold. With high performance gear protection and longer synchro life and satisifies the gear oil viscosity requirements of 70W, 75W, 80W, and motor oil viscosities of SAE 30, 10W30, and 5W30. Recommended for GL-1, GL-3, and GL-4 applications, as well as where most special synchromesh fluids are specified.

ABOUT RED LINE GEAR OIL FOR MANUAL TRANSMISSIONS
 
  • Appropriate coefficient of friction for most manual transmission synchronizers (other's synthetic gear oils are often too slippery for proper synchro engagement)
  • Red Line offers lubricants to pinpoint nearly every transmission application
  • MTL & MT-90 are not for use in differentials with hypoid gears
  • Excellent gear and synchro protection, balanced slipperiness for easier shifting in cold climates
  • Excellent for high- and low-mile transmissions
  • Compatible with petroleums and other synthetics

Tech Note: Recommended for 1989-1996 Corvette ZF Manual Transmissions
