You are giving more credit to GM here than they deserve.

This transmission is part of a joint-venture between General Motors and Ford Motor Company to split development of two transmissions, a longitudinal 10-speed and transverse 9-speed. Ford led the design of the 10-speed transmission, as well as filing the design patents for said transmission. According to an official report by the SAE (Society of Automotive Engineers) the design of the 10-speed gearbox is essentially all Ford, while GM was responsible for designing the 9-speed 9T transverse automatic gearbox. As part of their joint-venture, Ford will let GM use the 10-speed transmission with rights to modify and manufacture it for their own applications. In-exchange for Ford's 10-speed transmission, General Motors will let Ford use its 9-speed transmission for front-wheel drive applications; Ford ultimately declined use of the 9T.[2] [3][4]

This 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. Each company will manufacture its own unique version of the transmissions in their own factories.[1][2] The 10-speed transmission was designed by Ford, while GM designed the 9-speed transmission which is used in transverse applications.[3][4]

Wow not sure what your getting at mucho copy/paste but yeah I am aware of all that info thanks ... but what does this conversation have to do with the 9 speed fwd auto lol .. I was only talking about the A8 (8l90) vs the A10 (10l80 in the SS) in the 6th gen SS only and brought up the 10r80 in the Mustang GT to point out they are having issues now also as they are pushing them and no trans is unbreakable. Then your saying it's Ford's fault a Stock SS with the A8 is faster than the SS with the A10 since I'm giving GM too much credit lol. I get what your saying but I'm not concerned with giving credit for either A10 trans.
