Transmission fluid and gear oil

Blue Diamond severe duty formulas is Hot Shot’s Secret new transmission fluids and gear oils for all vehicles that experience heavy loads, towing or challenging terrain including commercial or utility vehicles, semi-trucks, motorhomes, tractors and off-road vehicles where there is an excessive demand on transmissions and gears.

Blue Diamond severe duty transmission fluid and gear oil formulas utilize 100% poly-alpha-olefin (PAO) Group IV synthetic oils and high-quality Group V esters.  

It also uses Hot Shot’s patented FR3 nano technology which provides a higher level of energy efficiency for improved shift response, reduced noise and vibration, and horsepower gain up to 3%.

Both Transmission Fluids and Gear Oils:

  • offer longer transmission and gear protection and performance
  • offer extended drain intervals
  • ensure improved oxidation resistance and thermal stability
  • reduce deposits, varnish and sludge that can cause costly breakdowns
  • reduce heat transfer with improved oxidation stability for maximum protection

Blue Diamond Severe Duty Transmission Fluid is offered in two types: a Multi-Vehicle ATF covering numerous applications and a version for Ford Type F / Allison C4 spec transmissions.

It is offered in three viscosity levels: 75W-90, 80W-110 and 85W-140.
