Ford F-150 harsh shifting problems

Filed Nov 9, 2026 · Transmission · MD

At approximately 89,000 miles, my vehicle experienced a suspected CDF drum bushing failure in the Ford 10R80 10-speed automatic transmission. Symptoms included delayed, harsh, and erratic shifting, intermittent loss of gear engagement, and unexpected gear changes that created serious safety hazards. While traveling approximately 60 mph in ninth gear, the transmission unexpectedly lost engagement, indicated first gear, then abruptly returned to ninth gear with a violent jolt. This triggered TCM diagnostic code P07F6 (Gear 9 Incorrect Ratio). The transmission also repeatedly failed to engage third or fourth gear, instead fluctuating between first and fourth with little to no power. This created dangerous situations when merging into traffic and making left turns across oncoming traffic because the vehicle could not reliably accelerate when needed. An authorized transmission repair facility identified the CDF drum bushing as the likely failure point, consistent with Ford TSB 23-2250, which addresses known 10R80 transmission shifting concerns. The transmission was ultimately replaced with a remanufactured unit incorporating Ford's updated components intended to address the problem. Ford has documented awareness of these transmission issues, yet no major recall or meaningful customer assistance has addressed affected owners outside warranty coverage. I previously purchased an extended warranty and reported harsh shifting to dealership service advisors but was never informed of the applicable TSB. I was discouraged from scheduling repairs after being told there was a three-week wait and that rental coverage was uncertain if the repair was denied under warranty. The vehicle was primarily a daily commuter with minimal towing or hauling. Failure at 89,000 miles under normal driving conditions raises serious concerns about transmission reliability and safety. Unexpected loss of engagement, incorrect gear selection, and loss of acceleration at highway speeds create subst

Hi my name is [XXX]. I bought my 2021 F-150 used with 40k miles. I love my truck and spend the money to keep up with all of the maintenance in hopes that it will last me a long time. At 61k miles, my transmission blew which seems insane to me. These 10 speed transmissions and known CDF drum failures are happening to so many people I talk to. I’m filing a complaint bc even my new transmission is experiencing hard shifts already after driving it for 9k miles. How many transmissions will I have to go through before Ford takes accountability. It’s unfortunate that these trucks cost so much money and then you potentially have to dump another $20k into it before even reaching 100k miles. I’m filing a complaint because I believe Ford should recall the CDF drum failures a do right for the customer. To my knowledge, these issues were fixed around 2024 models. Additionally, my transmission went out on a toll road where the speed limit is 85mph. I lost significant power and had to reduce my speed to 55-60mph which is a huge safety concern when people are passing you going 30mph faster than you.

"| own a 2022 Ford F-150 with approximately 69500 miles and am reporting recurring problems with the 10-speed 10R80 automatic transmission. The transmission has experienced .Hard downshifts into 3rd gear rpm flaring upshifts from 4th and 5th gear. These incidents have occurred when timing to a stop and during acceleration . This issue happens more often than not and I feel like at any moment the transmission could fail when it downshifts hard . The problem has occurred starting around 55000 miles , and the vehicle has Taken to my local ford dealer where it had the CDF drum replaced various clutch plates , as well as a driveshaft that was damage due to the hard shifts . Basically an overhaul at 59000 miles . Here I am today at 69000 miles and the hard downshift are happening again with occasional flared shifts . I am concerned that the transmission may unexpectedly change gears, lose power, or behave unpredictably while driving, creating a potential safety hazard for the driver, passengers and others on the road. I am asking the federal safety agency to document this complaint and investigate whether these recurring 10R80 transmission problems, including possible CDF clutch drum or sleeve issues, represent a safety defect affecting Ford F-150 trucks."

It will lose all power sometimes during 1-2 or 1-3 shift and not complete the shift causing you to be powerless in front of oncoming traffic while turning left on green across traffic. Then eventually slams into gear violently. This last time was not the first but two of my kids were in the truck this time. I have not had it to the dealer yet but after much research online this is a known problem and I have a pretty good idea of what they’re going to tell me. No check engine light.

A sudden transmission slip or hard shift into 8th gear every time. feels like someone is hitting the brakes just slightly when driving 40-50mph transitioning from 7th to 8th. sudden jerk when shifting into 4th more irregular but once a day at least.

My transmission hard shifts and stalls out. It was also low on fluid in January 2026, but it was not leaking. When pulling out from intersections with oncoming cars the transmission stalled. It has also stalled on the freeway. Yes, a ford dealership confirmed it. No warning lamps. I was told ford probably won’t cover the whole cost of this repair even though it’s a known issue

The contact owns a 2016 Ford F-150. The contact stated that the vehicle was previously repaired under the federal safety agency Campaign Number: 26V237000 (Power Train); however, the failure occurred after the recall repair. While starting the vehicle, the transmission started out at 5th gear with the engine revving, and while driving at various speeds, the transmission slammed into gear before accelerating. The vehicle then went into LIMP Mode with the transmission and check engine warning lights illuminated. The vehicle was taken to the dealer, who determined that the lead frame and PCM were normal, but the transmission might need to be replaced. The manufacturer was notified of the failure by phone. The failure mileage was approximately 163,000.

Transmission has hard/harsh shifts and delayed gear engagement that began around 56,000 miles and have become much worse at 68,000 miles. The delay in engagement when accelerating from a stop, pulling into traffic or merging is a safety concern. A Ford dealer performed a transmission adaptive relearn and software update, but the symptoms continued. The dealer did not verify hydraulic leakage or perform the full diagnostic described in Ford TSB 25-2126 (MC-11016931-0001, harsh/delayed shifts on 2017-2020 F-150), and the only recommendation was to replace the entire transmission at roughly $5,000 after the powertrain warranty expired at 60,000 miles. The incident date entered is today because the symptoms are ongoing and progressive: they developed gradually since about 56,000 miles and are heading toward ultimate transmission failure. Safety concerns: hesitation and delayed engagement when pulling into or merging with traffic, the truck possibly rolling back when engaged on hills, and loss of reliable power on hills.

On XXX at approximately 6:50 AM, I was backing out of my driveway. After entering the roadway, I came to a complete stop and shifted from Reverse to Drive while in Normal drive mode. Immediately upon shifting into Drive, the vehicle lurched forward and rapidly accelerated without any accelerator pedal input. My foot was not on the accelerator. The vehicle accelerated to approximately 15-16 MPH and continued moving under power. I had to quickly steer to avoid striking my brick mailbox. The vehicle continued moving until I applied the brakes and brought it to a complete stop. After stopping, the engine RPM returned to normal and the vehicle then operated normally. No warning lights or messages were displayed. This event created a significant safety hazard and nearly resulted in a collision. In addition, the vehicle has experienced intermittent transmission and driveline issues since it was new. Symptoms include harsh upshifts and downshifts, gear hunting, shuddering, driveline clunks, RPM fluctuations under steady throttle, and jerking during acceleration and deceleration. Some downshifts have been severe enough to make the vehicle lurch as if lightly rear-ended. Other events have felt similar to placing a vehicle in Park while still moving. I have experienced abrupt downshifts while slowing from approximately 40 MPH, rapid multiple-gear downshifts accompanied by shuddering, harsh shifts while coming to a stop at low speeds, and repeated gear hunting in traffic. The symptoms occur intermittently, often at low speeds, during the first few miles of driving, and sometimes while traveling uphill. I have returned the vehicle to Ford of [XXX] three times for these concerns. The dealership has been unable to duplicate the condition and no repairs have been performed. I am concerned that the unintended acceleration event and longstanding transmission/driveline abnormalities may be related to an underlying powertrain, transmission, or electronic control defect.
