![]() However, Ford owners should be aware of the following complaints about the units. The 8F35 is too new to be seen frequently in transmission shops since it is still under the manufacturer’s warranty. It also borrowed parts already in inventory for the 10R transmission. This saved weight and reduced the number of valves needed in the system. Ford also redesigned the valve bodies and the oil pump assembly to use the same software platform used by the 10-speed unit. Still, it is a more complicated unit to control because it applies the torque converter clutch toward the impeller assembly rather than the cover. Borrowing the 10R torque converter saves space and weight. These changes made the 2-3 shift step very small, and the transmission acts as a 7-speed under most driving conditions.įord also decided that they would use several design features they had used in the 10-speed platform. Essentially, Ford decided to remove the 4th gear, among other adjustments. The result was the 8F35 transmission.įord decided that there was no real advantage to having nine speeds, and the extra gear added weight and cost that didn’t improve fuel economy. Where GM had focused on drivability and smooth shift transmissions, Ford decided to focus on improving fuel economy. With that in mind, Ford significantly changed the base GM 9-speed transmission. The 2019 Buick Envision actually lost one mpg over the previous model’s 6-speed automatic transmission! For instance, the 2017 Chevy Malibu with the new 9-speed transmission gained only one mpg on the highway over the previous model’s 8-speed. Ford felt that the GM 9-speed did not improve enough fuel economy over existing 8-speed units, which has undoubtedly been seen with GM automobiles using the new 9-speed. ![]() Ford has introduced two 8-speed transmissions, one based on the GM 9T and the other a rework of a 6-speed transmission that GM and Ford partnered on back in 2002. The 10-speed has been used in Ford’s F150 pickups and Mustangs, while GM has used it in their Corvette and Camaro and their larger SUVs.Īs befitting any great rivalry, Ford decided that the GM 9-speed offering wasn’t quite up to their standards and opted to make some changes. The 10-speed transmission is intended for longitudinal (rear-wheel drive) applications, whereas the GM unit is for transverse (front-wheel drive) usage. Ford shared its new 10-speed transmission with General Motors to use GM’s new 9-speed transmission in select Ford vehicles. It is not surprising that transmission engineering became a target to join forces.Ī few years ago, the two companies agreed to share transmissions for use in their domestic products. This has occurred a few times in the last 20 years but often on the most complex vehicle systems. As economic instability motivated companies to find ways to increase efficiency and meet new governmental fuel economy standards, Ford and General Motors have found it beneficial to work together. The two most iconic American vehicle manufacturers are competitors and yet still partners. ![]()
