The 6R is a six-speed automatic transmission for longitudinal engine placement in rear-wheel drive vehicles. It is based on the ZF 6HP26 transmission[1] and has been built under license by the Ford Motor Company at its Livonia Transmission plant in Livonia, Michigan. The 6R debuted in 2005 for the 2006 model year Ford Explorer and Mercury Mountaineer.
The 6R80 was available in 2009–2017 Ford F-150 trucks (and 2018–2020 only paired with the 3.3L V6 engine). It features torque converter lockup capabilities in all six gears and an integrated "Tow/Haul" mode for enhanced engine braking and towing performance. For the 2011 model year, the transmission was revised to provide smoother shifts, improved fuel economy, and overall better shift performance. Most notable of the improvements was the addition of a one-way clutch that provided smoother 1–2 up-shifts and 2–1 down-shifts. The transmission has a relatively low 1st gear and two overdrive gears, the highest of which is 0.69:1. This provides exceptional towing performance when needed, while maximizing fuel economy by offering low engine speeds while cruising.
The 6R80 can be found behind the 3.7L V6 all the way up to the 6.2L V8. Ford has stated that while the transmission is used in multiple applications, each transmission is optimized and integrated differently depending on the engine it is mated to. The 6R80 features "Filled for Life" low viscosity synthetic transmission fluid (MERCON LV), though a fluid flush is recommended at 150,000 miles if your truck falls under the classification of "Severe Duty" operation. The transmission, as used in the Ford F-150, has a fluid capacity of 13.1 quarts and weighs 215 lbs.
Specifications
Preliminary Note
The 6R-transmissions are based on the ZF 6HP gearbox. The gear sets of the 6R140 are deviant.[2]
