2020 Ford F-250 SD: harsh or hard shifting

Filed Jul 23, 2026 · Transmission · TN

10r140 paired with 6.7 powerstroke in a 2020 f250 build date 11/19 at the Kentucky plant. My truck specs and build date and location is in the timeframe of the planetary gear recall, ford has also issued tsb’s about the cdf bushing that should have been a recall because it is a design flaw on every 2020-2022 model truck. It’s not fair that we should have to pay for a tsb bc we don’t have warranty left. My truck has 84,000 miles but is out of the 5 years warranty period. Symptoms I am having with my transmission are: Harsh engaging to drive and reverse Flair shifts bad sometimes almost like it goes into neutral between changing gears Has shifted from 4th to 1st instead of 4th to 5th or 6th, then it started shifting normal right after. Had my factory 3250rpm limiter not been moved to 4500rpm the truck would have locked the rear wheels up and possible caused driveline damage or other damaged. Also had a car been behind me when this happened I would have been in a wreck because it slammed to a low speed and the car would have rear ended me. Slips in 4th and 7th gear the most but sometimes in other gears Bumps when it shifts a lot of the gears Sometimes shudders and shakes and will almost make like a pop noise Will clunk on downshift from 5-3 Sometimes clunks when upshifting 3-5 I have had the truck looked at by an independent diesel mechanic I use and he said there is a problem somewhere in the transmission, it’s either planetary gear or cdf bushing has moved or the drum itself has cracked. The component itself has not been inspected because the only was to inspect this is to tear the transmission down. The pan has been dropped and had a lot of metal material on the magnet. No codes on the dash but my mechanic said I had dtcs stored for the transmission. I have created a case claim with Ford trying to see if they will extend the recall for the known issue but I have had zero luck with them. I have videos of the issues but can’t upload them on here.

The transmission would hang up in 7th gear when stopping at red light, caution light or stop signs without warning. It would roll like normal when letting of brakes however when out in the middle of traffic stop signs or caution lights the truck would not move and would not shift as it was hung in 7th gear. The only way to get the truck back in 1st gear was to place the truck in park and turn the ignition off then restart the vehicle. This has happened 3 different times post bringing the truck to silsbee ford for a ecm and tcm reprogram. Originally called dealer back to reports extreme rough shifting and was told they did not mess with anything in the transmission and it was not due to anything they did, never received a call back from manager. No warning lights messages ever appeared to show the transmission had failed to down shift into first gear at the stop lights. All three of these events happened while my 7 year old child was in the truck and two of the times it was a near miss and narrowly avoided accidents. Prior to this since around 50,000 miles truck would shift rough with rough engagement into 3,4th,5th,6th, gears with frequent flare shifts and was told by dealers this was normal characteristic of the transmission.

When shifting into drive the truck will lurch forward, a very hard shift. It also does the same thing in reverse. Several times the if my foot was not pressing very hard on the brake when shifting into drive or reverse the truck would lurch forward several feet. It there was an obstruction or person in front of the truck it would have put them at risk of being hit. While driving on cruise control it is very slow to shift and will skip multiple gears when shifting down when going up a hill. Sometimes also going downhill. This can cause the truck to slow down rapidly without a brake indicator which could cause a rear end collision if there is someone following closely. The truck is only 4.5yrs old and has 60,597miles. Symptoms started about 3-4months earlier when truck was well under 60,000 miles however I was unable to get it to the dealer until 60,597 which puts the truck out of warranty. The dealer was able to reproduce the issues and performed a code reset as well as a reprogram and the issue was not resolved. Dealer tore down the transmission and said one of the clutch packs in the transmission has failed along with several other parts. It is now requiring a full rebuild or replacement. There were no warning lights, alarms or messages. Date below is approximately when symptoms started occurring. I do not yet have my vehicle back so do not have the full report from the dealer. I will submit when I receive my vehicle back.

The truck slips out of gear for no reason, suffers very hard shifts causing the truck to jerk, and skips gears making it impossible to drive safely. Also, I lost power on the freeway several times and the truck would up shift and down shift erratically causing issues maintaining speed in traffic. I took the truck to the Ford dealer and was told I needed a new transmission. Ford has issued a recall for the Diesel truck with this transmission but refuses to repair other trucks with the same faulty transmission. This truck costs almost $60,000 new, was built in January 2020 with a faulty and dangerous transmission but ford is refusing to help their customers.
