Additional Notes

  • The BMW 4 Series Gran Coupé F36 manual transmission fluid specifications cover three distinct engine variants across the 2014-2020 model years: the N20-powered 428i, the 430i, and the 435i.
  • The 428i Gran Coupé with the N20 engine carries a 1.4-liter manual transmission fluid capacity across both the 2014-2015 and 2015-2016 model year entries, with both specifying fluid conforming to the MTF-LT3 label standard.
  • MTF-LT3 is a BMW-defined manual transmission fluid specification requiring a low-viscosity, long-life lubricant. Transmission units bearing the MTF-LT3 label are designed to accept only fluid meeting that specification, making the label notation on the 428i and 430i entries a compatibility-critical detail.
  • The 430i Gran Coupé carries a 1.3-liter capacity explicitly designated as a service fill, meaning the figure represents the amount of fluid used during a routine drain-and-refill procedure rather than the transmission's total internal volume.
  • A service fill value is typically lower than an overhaul or total fill capacity because some residual fluid remains in the transmission after a standard drain. The 430i's 1.3-liter service fill figure reflects this distinction across both the 2016-2019 and 2019-2020 entries.
  • The 435i Gran Coupé holds the smallest manual transmission fluid capacity among the three variants at 1.2 liters, and unlike the 428i and 430i entries, the 435i specification carries no MTF-LT3 label notation.
  • Across all six rows, the use condition is listed as normal, meaning the stated capacities apply under standard operating conditions rather than a severe-use or extended-service schedule.
  • The capacity steps down progressively from the N20-powered 428i at 1.4 liters, to the 430i at 1.3 liters, to the 435i at 1.2 liters, reflecting differences in the manual transmission units paired with each engine variant.
