Red Line MT-90 is the best fully synthetic gear oil for the MA70 Toyota Supra Non-Turbo W58 transmission in our opinion! MT-90 is also excellent for the Lexus IS300 W55 transmission and the Toyota MR2 E153/S54 transmissions. This is the price for (1) U.S. Quart. You will need to order (3) for your W58, W55, E153, or S54 transmission.
Since most GL-5 gear oils for differentials are too slippery for manual transmissions, Red Line offers these products that ensure proper shifting while providing ultimate wear protection
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
MT-LV, MTL, MT-85 & MT-90 are not for use in differentials with hypoid gears
Excellent gear and synchro protection, balanced slipperiness for easier shifting in cold climates
