Ford 6R transmission

Template:Short description Template:Short description Script error: No such module "Infobox".Script error: No such module "Check for unknown parameters".

The 6R is a 6-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 6R 80 was available in 2009–2017 Ford F-150 trucks (and 2018–2020 only paired with the 3.3L V6 engine). It features 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 6R 80 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 6R 80 features "Filled for Life" low viscosity synthetic transmission fluid (MERCON LV), though a fluid flush is recommended at Script error: No such module "convert". 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 Script error: No such module "convert". and weighs Script error: No such module "convert"..

Basic concept

A conventional planetary gearset and a compound Ravigneaux gearset is combined in a Lepelletier gear mechanism,^[2] to reduce both the size and weight. It was first realized with the 6HP from ZF Friedrichshafen. Like all transmissions realized with Lepelletier transmissions, the 6R also dispenses with the use of the direct gear ratio, making it one of the very few automatic transmission concepts without such a ratio.

It also has the capability to achieve torque converter lock-up on all 6 forward gears, and disengage it completely when at a standstill, significantly closing the fuel efficiency gap between automatic and manual transmissions.
