P2704 on Ford by model: symptoms, diagnosis and fix
The 2019-2023 Ford Transit Connect equipped with the 8F35 8-speed automatic transmission experiences transmission shuddering, harsh engagements, slipping, and premature failure. Ford issued Technical Service Bulletin 22-2281 (since superseded by 24-2092 and 25-2550) for 2019-2022 Transit Connect vehicles built on or before July 1, 2022 with the 8F35 transmission, addressing slipping, harsh engagement and clutch DTCs caused by worn needle bearings in the output planet carrier assembly. FordTransitUSAForum.com documents a 2019 Transit Connect XL 8F35 transmission failure at the 75,000 mile mark. Eng-Tips.com engineering forums discuss the inherent shudder issue in the 8F35 torque converter clutch. The transmission issues are exacerbated by commercial use patterns - frequent stops, loaded cargo, and city driving accelerate wear on the torque converter clutch and internal clutch packs.
Common Symptoms
- Shuddering during light acceleration at 25-45 mph
- Harsh or jerky gear shifts
- Delayed engagement from Park to Drive
- Transmission slipping under load
- Check engine light with transmission codes
- Transmission warning message on dashboard
- Grinding or whining noise from transmission
- Vehicle hesitates or surges at low speed
How to Fix
First step: check for TSB coverage and have the dealer perform a transmission fluid change with genuine Motorcraft Mercon ULV fluid and a TCM software recalibration. For 2019-2022 Transit Connect built on or before 07/01/2022, Ford TSB 25-2550 addresses 8F35 slipping and harsh engagement by replacing the output planetary assembly. If shudder persists after fluid change and reprogram, the torque converter may need replacement ($800-1,500). Complete transmission replacement for internal failure runs $3,000-4,500. The powertrain warranty (5yr/60k miles) should cover this on newer vehicles.

On some Explorers with the 10R60 ten-speed automatic, engagement into gear or shifts can be harsh or delayed, sometimes with the check-engine light on and transmission codes stored. Ford attributes it to transmission-control software, the solenoid ID strategy and/or sticking valves in the main control valve body. It affects 2020–2023 Ford Explorers equipped with the 10R60 ten-speed automatic that show the symptoms or codes listed in bulletin 23-2352 (the bulletin also covers 2020–2023 Aviator and 2021–2023 Bronco with the 10R60).
Common Symptoms
- Harsh or delayed engagement into gear
- Harsh or delayed shifts
- Check-engine light on with transmission codes stored
How to Fix
Have a Ford dealer confirm the symptom and check for later PCM/TCM software. Bulletin 23-2352 specifies a PCM/TCM software update and adaptive learning drive cycle first. If the condition remains and one of the listed codes is stored, the main control valve body is serviced; without codes, vehicles built on or before 1-Nov-2021 first get a transmission solenoid strategy reprogram, and later builds go to the valve body. Ford notes shifts can feel firmer than normal for several days while the adaptive strategy relearns. Normal warranty rules apply; this is not a recall or a promise of free repair.

Frequently asked questions
What does P2704 mean on a Ford?
P2704 stands for "Transmission Friction Element D Apply Time Range/Performance." This transmission code means the time it took to apply friction element 'D' (a clutch or band inside the automatic transmission) was outside the acceptable range or performed poorly. The transmission computer times how quickly each internal clutch/band engages during shifts; an apply time that's too long or inconsistent indicates worn friction material, low pressure, or hydraulic control problems. You may feel slipping, delayed or harsh shifts, or flaring (engine revving up between gears). It generally points to internal wear or a fluid/hydraulic issue developing in the transmission. On Ford it is documented across 2 models: Transit Connect, Explorer.
What are the most common causes of P2704?
The most common causes of P2704 are: Worn friction element (clutch/band) D, Low or degraded/contaminated transmission fluid, Faulty shift solenoid or pressure control solenoid, Valve body wear or stuck valve, Internal hydraulic pressure leak, Clogged transmission filter or passages, Faulty transmission control module (TCM). The specific cause varies by vehicle.
How much does it cost to fix P2704 on a Ford?
Published repair estimates on Ford range from $200 to $4,500 depending on the model and root cause. If an issue mentions a recall or campaign, check your VIN with the manufacturer or NHTSA and confirm eligibility and coverage with a dealer.
