SHP® Synthetic MTF

Premium Full Synthetic, Fuel-Efficient Heavy-Duty Manual Transmission Fluid, API MT-1; Eaton PS-386 Approved

Kendall® SHP Synthetic MTF (Manual Transmission Fluid) is a full synthetic, fuel-efficient transmission lubricant designed for use in heavy-duty commercial manual transmissions operating in extreme temperatures and/or extended service intervals. It combines outstanding low-temperature properties without standing oxidation resistance and thermal stability at high temperatures to provide excellent all-climate, year-round performance. It provides improved fuel efficiency of up to 1.5% compared with previous-generation SAE 50 manual transmission fluids.

Features & Benefits

  • Extended drain, all-season performance
  • Outstanding oxidation resistance and thermal stability to minimize sludge and varnish formation
  • Improved low-temperature properties for easier shifting in cold weather
  • Improved fuel efficiency
  • High shear stability
  • High load-carrying capacity
  • Protects against component wear and gear micropitting
  • Protects against rust and corrosion
  • Good foam resistance
  • Excellent seal compatibility


  • Heavy-duty manual and semi-automatic transmissions in commercial vehicles where the OEM specifies a non-EP SAE 40 or SAE 50 API MT-1 transmission fluid, an API GL-1 SAE 90 gear oil, or an SAE 40 or SAE 50 heavy-duty engine oil
