    Excellent Manual Transmission fluid.

    The Red-Line MT-90 is the best manual transmission fluid for older car. I have a old Toyota Pickup 4x4 and the transmission feel smooth like new and the shifting in cold or hot weather is very smooth and easy.

    5 speed manual shifts buttery smooth now

    My gears in my Toyota e153 transmission shift very smooth now. Much better than other name brand synthetic gear oil for synchromesh.

    Expensive but worth it. Good for Nissan Hardbody 4x4.

    Makes on old transmission last forever. Eliminated the whine that was coming from my transmission. Eliminated the gear noise. Gave me smooth shifting. It's expensive but worth it if you want to guarantee your old transmission gives you many more miles.

    Good stuff, works well

    Good stuff! We put it in my Toyota Tercel 6-forward-speed transmission with 304K miles on it, sluggish and requiring double-clutching. Now it's synching into all but first gear, smooth as silk.

    Hard to find lube for older transmissions

    GL4 to protect older transmissions with yellow synchronizers and synthetic for long life and superior lubrication.
