Designed for transmissions and transaxles - helps to slow synchros for easier shifting across a broad temperature range. Contains extreme pressure additives like our 75W90 GL-5 oil, but lacks friction modifiers to balance slipperiness. Improved copper corrosion protection to prolong synchro life. Helps with lock-up on weak limited-slip differentials-compatible with Red Line Limited Slip Friction Modifier for tuning slippage. Also used with clutch-type LSDs in racing for maximum lock up

Features:

- 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-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

- Excellent for high- and low-mile transmissions

- Compatible with petroleums and other synthetics
