The Ford 8-speed automatic transmission is developed as part of a collaboration between Ford and General Motors (GM). The 8-speed transmission is part of the 8F series units and is designed for use with various Ford vehicles. Here are some key points about the Ford 8-speed automatic transmission:
Collaboration with General Motors
– Ford and GM have collaborated on the development of a series of 8 and 9-speed front-wheel-drive transmissions.
– The 8-speed transmission is part of the 8F series units, which are developed in collaboration with GM.
Features and Specifications
– The 8F series units use Ford Mercon U LV fluid.
– The eight forward speeds are achieved by using just two driving clutches and four brake clutches.
– The 8-speed transmission is designed with various gear ratios, including first, second, third, fourth, fifth, sixth, seventh, and eighth gears, along with a final gear ratio.
– The transmission is equipped with a hydraulically actuated sprag and a selective one-way clutch (SOWC).
Decision Not to Use GM’s Nine-Speed Automatic Transmission
– Ford decided not to use GM’s nine-speed automatic transmission, despite a previous collaboration between the two companies.
– Ford felt that the GM 9-speed did not significantly improve fuel economy over existing 8-speed units, leading to Ford’s decision to change the base GM 9-speed transmission.
– Based on Ford’s decision to change GM’s transmission to an eight-speed, it appears that more gears isn’t always better.
In summary, the Ford 8-speed automatic transmission is a result of collaboration between Ford and GM, and it offers various features and specifications designed to enhance performance and fuel efficiency in Ford vehicles.

What is the problem with the ZF 8 speed transmission?
A design defect in the ZF 8-Speed transmission is that the “A” Clutch backing plate flexes under high line pressure, destroying load capacity. This results in 7th and 8th gear flutters as well as shaky or slow takeoffs.

Is the ZF 8 speed transmission reliability?
The ZF 8 Speed has developed a reputation for being one of the best automatic transmission systems on the market today. Made by German supplier ZF, it has a long, decorated history of success within the automotive industry in both passenger and commercial vehicles.
Who makes Ford automatic transmissions?
The Ford–GM 10-speed automatic transmission is part of a joint venture between Ford Motor Company and General Motors to design and engineer two transmissions: a longitudinal 10-speed transmission and a transverse 9-speed trans-axle.
Are Ford and GM transmissions the same?
That 10-speed automatic is the one that Ford and GM are both now gearing up to produce in their own plants. While each automaker will have their own version of the transmission, with unique software and other proprietary tweaks, the basic units are the same.
Does Ford make their own transmission?
The Ford PowerShift is a six- or seven-speed dual-clutch automatic transmission, produced by the Ford Motor Company.
Does Ford use Allison transmissions?
General Motors, Ford and Dodge commercial trucks offer vehicles with the Allison transmission. The Allison Division of General Motors introduces the VH unit, a member of the V-line transmissions, with hydraulic and direct clutches.
What is the life of the ZF 8 speed transmission?
100,000 miles
Per Gareth Foley at FCP Euro, “BMW rates these transmissions for a ‘lifetime fill,’ however, through our channels at ZF and speaking with the engineers of those transmissions, we’ve learned that the transmissions are tested to 100,000 miles with an “acceptable rate of failure” on the original fill.
What are the common problems with the ZF 8-speed transmission?
A design defect in the ZF 8-Speed transmission is that the “A” Clutch backing plate flexes under high line pressure, destroying load capacity. This results in 7th and 8th gear flutters as well as shaky or slow takeoffs.
Does Chevy use Ford transmission?
But GM still gets to use the 10-speed Ford developed
In reality, things went a little differently. Automotive News reports that while GM has been happy to use Ford’s 10-speed in several vehicles such as the Chevrolet Camaro ZL1 and Cadillac Escalade, Ford has yet to use GM’s nine-speed.
