Automatic Transmission Control Module Problems of Ford Mustang

I am bringing in my 2017 Ford Mustang ecoboost premium due to a serious transmission problem. The vehicle’s 10r60 / 10r80 automatic transmission becomes stuck in drive/sport mode and fails to shift properly, which is a significant safety concern since it prevents me from reliably selecting park or neutral when needed. I am aware of multiple Ford technical service bulletins (tsbs) and updates related to this transmission family, including but not limited - TSB mc-10236680 (may 30, 2023) – 10r60 / 10r80 automatic transmission – harsh/delayed engagement and/or harsh/delayed shift - identifies pcm/tcm software issues, solenoid strategy concerns, sticking valves in the main control valve body, and axial movement of the cdf clutch cylinder sleeve. - calls for pcm/tcm reprogramming, adaptive learning drive cycles, and in some cases valve body or clutch component replacement. - TSB 23-2250 (2023) – 10r60/10r80 harsh/delayed shifts / engagement - describes corrective procedures including transmission accelerated main control break-in routine, adaptive learning cycles, and parts replacement if necessary. - TSB 18-2079 (2018) – 10r80 harsh/delayed shifts, dtc p0711 - calls for pcm reprogramming to correct transmission shift concerns. Given these official Ford bulletins acknowledge issues with this transmission design, I am requesting that the dealership: 1. Check for and apply all available pcm/tcm software updates as outlined in the above tsbs. 2. Perform adaptive learning drive cycles or transmission accelerated main control break-in procedures where applicable. 3. Inspect for valve body or cdf clutch cylinder defects if symptoms persist. 4. Confirm whether this VIN is covered for these repairs under TSB or goodwill consideration, given the clear overlap between my symptoms and Ford’s published bulletins. Because this is a safety issue (vehicle stuck in gear, inability to properly engage park/neutral).

I have a 2013 Ford Mustang v6 coupe with automatic transmission. I purchased the car certified pre owned through ken grody Ford in carlsbad, CA with less then ~11,000 miles on it in 2/2014. I have been complaining of a jerk/ knock at ~ 1-1. 6 rpm’s when idling & driving in stop and go traffic/ off ramps/ on ramps and parking lots - it appears to come from the transmission area. Fast forward to complaining over the years during service intervals ~ 2x a year for for the works service - oil/ lube/ etc , dealer did a transmission control module computer reset & advised to monitor for symptoms in 11/2020. As covid was present, the car wasn’t driven much during. However the knock/ jerk between 1-1. 6 rpm’s has always been present, even returning after the tcm reset. Dealership was notified, and neglected to return calls or follow up. Fast forward to 9/15/2022, after 3-4 wks of calling and leaving voicemails to no avail from the dealership service department manager/ dealership. I set up an appointment for 9/15/2022. On 9/5 & night of 9/14/22, the car instrument cluster lighted up with all notifications, and dashes for the total mileage on the car, orange wrench light - indicating Ford limp mode, and low fuel popup (car was just fuels 1 hr prior to driving from costco for grocery) I left and drove up a hill when this occurred as I was going 40-45 miles per hour the speedometer dropped to 0 mph & the car barely drove beyond 5-15 mph. I pulled over at the nearest local street from the hill parked the car and powered off the engine. I had a obdii tool that indicates: global obd Ford. P0720(1 / 1) output shaft speed sensor circuit. Severity 2 of 3. I finally heard back from dealer after calling & escalating between 9/15-9/19, once I got ahold of the customer relations managers assistant she said the service manager/ customer relations manager would call back by today 9/20/22. The service mgr states I am out of wtty & need to cover cost of repair myself. TSB for trans. Is attac.

Intermittent loss of throttle with wrench light. Engine goes into derate, have to shut off car, let sit for 3-5 minutes, restart then ok until it occurs again. Loss of throttle at any time is unsafe. Two Ford dealers have tried to repair with no luck. They have replaced the throttle pedal assembly, the throttle body, and now the pcm. Problem is still present. Have an ongoing Ford customer service case #cas44568044-d6g8f8. Still awaiting resolution. Vehicle is still under 3/36 base warranty. Problem has been ongoing for a little over a year now.

Parking car into parking bay between building support and other car. With my foot on brake and at a stop I reached to place car in park when for no reason the car accelerated over a concrete parking stop, through a ditch, out of the ditch before striking another truck head on in the parking area across the ditch. My foot was on the brake the entire time and I did not touch the shifter at all! the car could be revving very high as it move forward and I pressed the brake pedal as hard as I could to no avail. Preliminary discussions with dealership have insinuated this could not have happened and they seem to be resisting to look into this mechanical malfunction. Very concerned this can happen again where someone could get killed!!.

Problems with vehicle's transmission. The first time the consumer took the vehicle in for service was for a noisy transmission and it was running rough. The dealer was unable to find a problem but topped of the fluid and reprogrammed the pcm. The dealer instructed the consumer to continue driving the vehicle and it would work itself out. The second visit was for the transmission again, however this time it was griding between first, second and third gears when cold. The dealer was unable to find a problem, but informed the consumer other Mustangs were having the problem and they were waiting on a bulleitn to see what could be done.

Pre-accident conditions: daylight, raining, car stopped at red light. A few minutes prior to arriving at the red light the driver's power seat moved all the way forward completly on its own accord after stopping at the red light I re-adjusted the driver's seat and when the light turned green I proceeded making a right turn in my normal "old lady" fashion. About 3/4 through the 90 degree turn the rear wheels lost traction and began to slide to the left. I immediately hit the brake and turned the wheel to the left. (I suppose it is possible that I accidently hit the cruise control button located on the wheel at this time). Anyway the car engine contiued to rev and the rear wheels continued to spin, driving me into a complete 360 degree turn, all the time with my food hard on the brake pedal. While in this spin the rear of the car jumped a median curb twice, crossed two lanes of asphalt, jumped another curb and finally crash into a concrete light pole. Only then did the car stall and the drive wheels stop spinning.

Traction control had to be replaced. Also, axle was defective, it shut down, causing vehicle to lose all power. Please provide additional information.
