The bucking and surging at very low speeds has plagued my Ford Edge since the first day I got the SUV back in Nov 2019. They reprogrammed the TCM probably 2 - 3 times and also replaced the transmission due to what they thought was a torque converter problem. None of those repairs ever fixed the bucking/surging issues at slow speeds. However after seeing your post I also just replaced the exhaust gas recirculation valve assembly (sensor along with the 2 preconnected rubber hoses and clamps) just 2 days ago. It now does seems to shift better at low speeds with no bucking but I have to drive it for another few weeks to be 100% sure that resolved my problem as well. Thank you for your post as this issue has been driving me crazy for almost 5 years.
For my 2019 Ford Edge, 2.0L engine I ordered Ford P/N K2GZ-9J433-C (Valve Exhaust)
