When we developed our Transmission Fluid Change Kits over 10 years ago, the MT82 Transmission Fluid Kit was the first kit released. Our MT82 Kit is still our most popular, we originated it and now we have simplified it to include the MGC Additive standard. 
This Fluid typically makes a drastic difference in shifting performance over the OEM fluid fill as well as most competitive brands that meet the Ford XT-11-QDC (Spec. WSS-M2C200-D2)
Vastly improves the shift performance of the MT82 6 speed manual transmission used in the Ford Mustang from 2011 to present day.

BG Syncro Shift® II was the foundational chemistry we rely upon. We have shipped thousands of quarts of this product to every corner of the world.
BG Syncro Shift® II Full Synthetic Gear Lubricant is specially formulated for manual transmissions, transaxles, transfer cases, and Haldex units. It is a full synthetic API GL-4 gear lubricant that provides unmatched film strength and wear protection. It provides exceptional resistance to mechanical shearing, has excellent low-temperature fluidity, and is safe for all steel, brass, and copper alloys. 
BG Syncro Shift® II is an API GL-4 gear lubricant blended to SAE 75W-75 viscosity and may be effectively used in all vehicles where engine oil, ATF, or GL-4 gear oil is specified as “service fill” for manual transmissions.
