CDF drums made before 2023 have physical design flawInteresting.
Is it a physical design flaw or is it a programming design flaw?
You would think that the transmission should be nearly identical to the GM 10L80. GM's 10L80 seems to not have nearly as many rough shift issues.
However, could making a programming change to the transmission mid model year result in different fuel economy numbers? Would Ford get penalized for making a modification that could potential cause the vehicle not to achieve it's EPA ratings?
