Automatic Transmission Control Module problems of the 2019 Ford Edge

Transmission has had the lumpy shifting issue at lower speeds/gears since we bought it used from a local Ford dealer. This appears to be a common problem if the reports in various internet forums is to be believed. Pcm was upgraded, didn't help. Now the lumpiness has increased to bucking, making the car close to undriveable. In addition when accelerating hard there is a considerable delay in actual increased movement, almost caused a wreck at one point.

2019 Ford Edge titanium awd, 91k miles. 8f35 transmission is severely jerking and shuddering at lower speeds around 20-35 mph. This causes erratic driving and lack of control when accelerating up to speed, especially on the highway. Has caused near-accidents for my family and I due to the car's erratic behavior. Ford has issued TSB 21-2389 to reprogram the pcm, but that does not resolve the issue. Ford dealership has told me the rear differential and torque converter need to be replaced to the cost of $9200.

The transaxle, torque converter, and/or pcm/tcm have suddenly, and rapidly started wearing and degrading to the point of requiring replacement. Available for inspection upon request. The vehicle had troubles shifting, finding/selecting gears, and as a result, would lurch or come to abrupt stops at low speeds, have difficulty accelerating which made it difficult to enter or exit intersections where there is great risk of collision. I had to very carefully choose and wait for the opportune time to enter/exit roadways where no other vehicles were coming in case the vehicle would not accelerate for 3-5 seconds when using the accelerator pedal. Problem has been reproduced since first occurrence and a dealer has inspected the components indicating that replacement is needed. There were no indications, warnings, alerts, or messages to suggest that an issue was occurring until after the first several instances of failure to shift. I tried to use a scanner to find obd2 codes, but there were none. A generic alert via the driver display was given, but it took 500+ miles for a more specific warning and obd2 codes to be generated. From my understanding, there have been hundreds of drivers that have experienced the same issues with the same/similar models of Ford Edge vehicles that use the same transmission. Note: I had experienced shifting difficulty/roughness, rpm variation, slow gear changes, delayed acceleration at ~60k miles. I had brought the vehicle in for service where transmission fluid was flushed. Approximately another 55k miles later is when my vehicle experienced the severe failures described above. This is similar to many other vehicle owners experiencing these issues at ~60k miles.

What happened: the torque converter/transmission system failed. My 2019 Ford Edge (VIN [xxx] , 75,000 miles) experiences a shudder and vibration under 60 mph during normal driving, with no diagnostic trouble codes present. This matches the condition described in Ford technical service bulletin (TSB) 25-2154 for the 8f35 transmission. The vehicle is available for inspection upon request. Safety risk: the shudder occurs during acceleration and highway merging. It causes the vehicle to hesitate and lurch, which puts myself, passengers, and nearby drivers at risk — especially when merging into traffic or crossing intersections. Loss of smooth power delivery creates a hazard that could result in a collision. Dealer confirmation: the problem has been diagnosed and confirmed by an authorized Ford dealer, who quoted approximately $2,800 for repair (torque converter replacement and pcm reprogram). Manufacturer involvement: the issue was presented to Ford motor company, who acknowledged the TSB exists but denied goodwill assistance to cover the repair, even though this is a known defect. Inspections: the vehicle has been inspected by the Ford dealer’s service department. No inspections have been performed by police or insurance representatives. Warning signs/symptoms: there were no warning lamps or error messages. The first symptoms (shuddering and jerking below 60 mph) appeared around [insert month/year you first noticed].

Purge flow valve had replaced by Ford service on 10/5/24. Car wouldn’t start after getting gas. Check engine light came on. Code was po496. Currently, upon acceleration @15-20 mph car starts jerking, buck, slipping, very hard to go hill. Took to Ford service for diagnostic on 10/15/24. Told torque converter shuddering on pids. Recommend replacing torque converter @ a cost of $5200. Per, reviewing many complaints on this same model & yr many haven’t had success with just replacing torque converter. It doesn’t fix issue. Transmission had to be replaced. Ford does have a TSB 21-2389 that supersedes TSB 21-2081 out. It states cars with 8f35 transmission may have this issue due to the software in the power train control module. Instructing, to reprogram the pcm & the transmission solenoid strategy. After reviewing all complaints on this issue, this solution does not correct problem. I was also told by Ford service; this wouldn’t fix the issue. From what I’ve read the way this transmission is engineered will likely cause it to always do this. Because Ford frankensteined the 6f35 (previous models) by inserting 2 gears in between existing ones, the transition from 1-2-3 will never be as fluid as 3-4, 4-5, and so on. Basically what is 1-3 on mine (8f35) is 1-2 on a 6f35. This quite frankly is a terrible transmission & only a matter of time before transmission goes completely out & someone gets killed. This year & model has numerous issues not listed here. Seems like as soon as warranty expires problems start popping up. Some issues pop up before warranty expires. This is getting dangerous & very expensive!.

In 2019 Ford removed the low gear option from the shifter dial. Customers were forced to manually shift using paddle shifters to access engine braking in steep grade situations. Current Ford tcm programming for 2019 and newer vehicles skips from first to third gear at 4mph, 900-1000 rpm, providing no engine braking ability in speeds below 25 mph when using paddle shifters. My vehicle manual states “selectshift does not automatically upshift, even if the engine is approaching the rpm limit, unless the accelerator pedal is at full travel. ” despite contradictions to how the Ford owners manual says my car should operate, the dealership says it’s working as intended. I believe this violates NHTSA standard section s3. 1. 2 of that states that “[in] vehicles having more than one forward transmission gear ratio, one forward drive position shall provide a greater degree of engine braking than the highest speed transmission ratio at vehicle speeds below 25 miles per hour. " third gear does not provide more engine braking ability than drive in speeds below 25mph. This is a safety issue which could lead to potential brake failure in long, steep grade situations and provides no engine braking ability.

In may of 2024 transmission downshifting hard at 35 mph as slowing down car milage was 67529. Took to dealer who performed diagnostics and verified a transmission problem; inspected fluid which was okay, performed TSB and reprogrammed pcm and reinstalled transmission strategy in module. Repairs done under warranty. Perform adaptive learn and noted it will feel different while driving for next few hundred miles. Six months later in November of 2024 transmission would hesitate, shudder, jerk between 20-40 mph and car mileage was 75937. Took back to dealer who did diagnostics, monitor pids and found the torque converter has failed causing shutter and also found the vehicle is flair shifting between gears. Checked fluid level and proper level is in transmission but fluid has meta debris. Dealer service representative advised it needs new transmission and would cost $800 or more to fix problem. Warranty expired at 72000 miles. We bought car new and had dealer perform all maintenance procedures and oil changes, etc. As noted in required maintenance schedule. We asked to speak with service manager who we saw in her office and we were told we'd need to make an appointment in late December or early January. We got no help from dealer or manufacturer, despite several technical service bulleting available at NHTSA showing transmission problems with 2019 Ford Edge. We finally got rid of the car but would say Ford Edges have definite transmission issues that may indicate a need for recall.

The vehicle was not repaired. The contact related the failure to Ford TSB number: 19-2103. The manufacturer was notified of the failure, and a case was opened. The failure mileage was approximately 30,000.

Transmission has been in the dealer multiple times due to transmission slipping, exhibiting a shudder/buck/jerk/hesitation to shift while accelerating and driving up to 35 mph. The software in the powertrain control module (pcm) was reset on multiple visits in an attempt to correct the issue prior to the physical partial repair of the transmission. At odometer reading 69,685 mi services performed vehicle serviced automatic transmission cooler flushed oil and filter changed torque converter replaced transmission checked transmission fluid flushed transmission rebuilt this vehicle is now out of warranty and is starting to experience transmission performance issues again (02/2026).

Sunday September 4th my 2019 Ford Edge with 35,995 miles, started idling rough, and white smoke started coming out of the tailpipes. I completed my drive to my sisters house and left it to set and cool down for about 5 hours. When I left to head home it lurched forward while coming to a stop sign and went dead. I started it back up and a bunch of white smoke came out of the tailpipes and it smelled awful so I barely pulled it off to the side. My brother in law came and picked us up and he said the car was way too hot to have been sitting for that long. I had my son in the back seat and this all scared him to death. Through all of this not one dashboard light came on. No engine overhearing light, no check coolant light, no check engine light - nothing. I had it towed to the dealership the next day. Dealership says they replaced the egr cooler and reprogrammed the pcm. Hopefully I have no further issues.

The contact owns a 2019 Ford Edge. The contact stated that while driving at various speeds, the vehicle was jerking, shuddering, with the service warning light illuminated. Additionally, the transmission occasionally failed to shift properly. The vehicle was taken to the local dealer who diagnosed the vehicle with pcm failure. The contact stated that there were metal shavings inside the transmission fluid and the transmission was fluid was burnt. The contact was informed that the transmission needed to be replaced. The vehicle was not yet repaired. Additionally, the rear driver’s and passenger’s side seat belts latch and buckle failed to remain securely closed. The contact was informed that the belt buckles needed to be replaced by the dealer. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 200.

Transmission jerks and acts as if it doesn't want to shift into place at speeds between 20-40 mph. As per Fords protocol had the pcm reprogrammed, but that has not helped. I am being told it is the torque converter, possibly the transmission itself. Apparently this is a common and costly issue with this transmission.
