1 Quart Redline MT-90 Transmission Oil, GL-4

$ 25.00



The preferred transmission oil for the C60/C64 series Toyota transmission found in 2ZZ-GE powered Lotus Cars. You MUST run GL-4 oils in the C60 transmissions.

  • 75W90 GL-4 gear oil (similar to SAE 5W40/10W40 engine oil viscosity)
  • Popular in Nissan, Mazda, Mitsubishi, VW/Audi, Lotus Elise/Exige, Toyota
  • Offers quicker shifts, perfect synchronizer coefficient of friction
  • Safe for brass synchros, as it lacks the reactive sulfurs found in most GL-5 oils that cause damage
  • High performance gear protection and longer synchro life
  • Eliminates notchy shifting, even when cold
  • Satisfies the gear oil viscosity requirements of 75W, 80W and motor oil viscosities of SAE 40, 10W40, and 15W40
  • Recommended for GL-1, GL-3, and GL-4 applications, as well as where most special synchromesh fluids are specified

NOTE: You will likely need 3 quarts to change the oil in a C60/C64 Lotus Transmission. Most changes will take between 2 and 2.5 quarts depending on how completely the oil is drained

This is 1 quart of GL-4 MT-90 Transmission Oil
