Redline MT-90 Manual Trans Fluid

SKU: 50304

$14.99 Sale price

Regular price $14.99

This is a great upgrade for your manual trans! This is one of the easiest "mods" to do for your trans. Drain old fluid, pour this in. The trans will shift quicker, feel less notchy, less wear on its components, etc!

  • 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-90 is 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
  • 75W90 GL-4 gear oil (similar to SAE 5W40/10W40 engine oil viscosity)
  • 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

    Most manual transmissions take a little over 2 quarts of fluid.

The price is per bottle.

 

F35 takes 1.8 bottles
F40 takes 2.8 bottles

Better than before

Installed new axles along with new gear oil. Car shifts and runs quieter.
