Manual Transmission Fluid Gear Lube GL4 75W-90

Manual Transmission Fluid 75W-90 GL-4

Formulated specifically for demanding manual transmission and transaxle applications – A Major seller here in Sioux Falls.

Towing, heavy hauling and performance driving create shock-loading conditions and elevated heat that threaten the performance and life of manual transmissions and transaxles. Making matters worse, horsepower, torque and towing capacities seem to increase with each new vehicle model year, increasing severity. AMSOIL Synthetic Manual Transmission Fluid 75W-90 is specifically formulated to reduce friction and maintain viscosity for long component and fluid life. It is designed to excel in severe-service conditions that exceed the limitations of conventional fluids.

Protects Against Wear & Heat in Severe Applications

Synthetic Manual Transmission Fluid 75W-90 is shear-stable and maintains its viscosity despite rigorous mechanical action. It provides a thick lubricating film and contains extreme-pressure additives to protect against wear in severe-service and shock-loading conditions common when towing or hauling. It resists thermal degradation and oxidation for excellent performance in high-temperature applications, such as the New Venture NV-4500 transmission, which retains heat due to its cast-iron housing and is often subject to increased torque from turbodiesel engines.

Customer Reviews on the Manual Transmission Fluid

Cheaper than the parts house – Way Cheaper than OEM

By SHANNON,  a  Verified Buyer from  Houston on  May 06, 2024
When you can get a superior fluid at a part store price, why would you buy anything else?

2019 Manual Tacoma

By ALEX, a Verified Buyer on April 30, 2024

2019 Tacoma TRD Sport Replaced factory MT gear oil at 25K. Immediate improvement in shift quality. The notchy feeling disappeared, and cold shifting is significantly smoother. The factory oil was not dark or degraded, but this oil is a marked improvement over stock. The bag packaging made the fluid swap so much easier. Just squeeze the gear oil into the transmission and drain any remnants into the next bag. No more pumps, injectors, gear oil mess, or any real issues. I don’t think I could go back to the plastic bottles after doing a fluid swap with this packaging.

Continuing Performance

By WILLIAM, a Verified Buyer from Bremerton, WA on January 20, 2024

So, in 0-degree weather it still runs better than the stock fluid ever did, notchy a moment but by the time I make the freeway 1/4 mile later it is already buttery. Love it!
