Product Description:
Red Line Synthetic MT-90 has a relatively constant viscosity over a wide temperature range that allows easier shifting and helps prevent whine and rattle at high temperatures. It has a coefficient of friction which allows rapid syncro engagement and it is perfect for high-speed upshifting and downshifting.MT-90 is shear stable and will retain its physical characteristics for extended periods. Note: not designed for use in rear-wheel drive differentials that require a GL-5 lubricant. 1 quart.
