How to diagnose and fix P2704: most-reported vehicles
Ranked by owner reports. Each card gives the symptoms, how to confirm the cause, the fix, parts and sources for that vehicle.
Ford Transit Connect · 2019–2023
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 a Technical Service Bulletin for 2019-2021 Transit Connect vehicles built before December 20, 2021 with the 8F35 transmission addressing slipping and harsh engagement concerns. 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. Earlier Transit Connect models with the 6F35 transmission also had recall campaigns (2013-2021 models). 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 2019-2021 Transit Connect built before 12/20/2021, Ford TSB addresses 8F35 slipping. 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.

Ford Maverick · 2022–2022
The 2.0L EcoBoost Maverick uses the same 8F35 eight-speed transmission found in other Ford applications (Edge, Nautilus, Transit Connect, Escape), where vehicles equipped with the 8F35 transmission may exhibit a shudder/buck/jerk while driving up to 35 mph (57 km/h) due to software in the powertrain control module (PCM) — this is documented in TSB 21-2389 for the Edge/Nautilus and is widely reported by Maverick owners as carry-over behavior. A separate but related condition involves transmission slipping concerns, harsh engagements and various clutch DTCs (sometimes with torque converter clutch DTCs), caused by worn needle bearings in the output planet carrier assembly (TSB 22-2281). Per the TSB, only 8F35 units built on or before Dec. 20, 2021 are flagged — which in practice means early 2022 model year Mavericks. Drivers typically feel a low-speed shudder under light throttle, harsh 2-3 upshifts on hills, or a flare on the 4-5 shift.
Common Symptoms
- Shudder, buck or jerk between 15-35 mph
- Harsh 2-3 upshift, especially on inclines
- Slip or flare on 4-5 upshift under light throttle
- Harsh engagement when shifting D↔R
- Metallic debris in transmission pan
- Delayed engagement when cold
How to Fix
The correction is to follow the Service Procedure steps to reprogram the PCM and the transmission solenoid strategy (labor op 212389A, ~0.9 hrs). After the adaptive strategy is reset, the computer begins a relearning process that may result in firmer than normal upshifts and downshifts for several days. If shudder persists after the reflash, the planet carrier bearings may need overhaul — early 2022 EcoBoost Mavericks built with 8F35 units before Dec. 20, 2021 are flagged for output planet carrier wear; shops keep finding slipping shifts, harsh D↔R, and metal glitter in the pan. A full overhaul per TSB 22-2281 is 16.4 hrs of labor and includes the output planetary carrier, overhaul seal kit, sun shell, and related hardware; replacement of solenoid pack/valve body and torque converter is commonly needed. Reflash cost is ~$150; a full overhaul outside warranty typically runs $3,500-$6,500, though full unit replacement can reach $8,000+.

Lincoln Aviator · 2020–2023
Some 2020-2023 Lincoln Aviators equipped with a 10R60 and built on or before December 23, 2022, or a 10R80 MHT and built on or before August 15, 2022, may have harsh or delayed engagement and/or harsh or delayed shifts. Ford TSB 22-2428 says the condition may involve PCM/TCM software, the transmission solenoid-ID strategy, sticking main-control valves, or axial movement of the CDF clutch-cylinder sleeve. The complaint may occur with or without a malfunction indicator and the bulletin's listed transmission DTCs. The symptom alone does not select a valve body, CDF cylinder, or complete transmission.
Common Symptoms
- Harsh engagement
- Delayed engagement
- Harsh shift
- Delayed shift
- Malfunction indicator with a bulletin-listed transmission DTC
How to Fix
Have a Ford/Lincoln-capable technician confirm the transmission and build date, retrieve PCM/TCM faults, and follow TSB 22-2428 in order. The bulletin begins with available PCM/TCM programming and an adaptive-learning drive cycle, then uses the stored faults and clutch behavior to select an accelerated main-control break-in routine. If the condition remains, the procedure can require main-control overhaul and, only after the bulletin's later tests fail, condition-specific internal transmission repair. Parts and coverage must be selected by VIN and the actual failed step; this record intentionally has no buy link.
Owner tips & cautions
- TipRecord the exact shift or engagement event and ask for the PCM/TCM fault report plus the TSB decision-tree step that failed before approving internal transmission work.
- WarningDo not order a valve body or CDF part from harsh shifting alone; Ford's procedure can resolve the condition through programming, adaptive learning, or clutch cycling before parts are selected.

Frequently asked questions
What does P2704 mean?
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.
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?
Repair costs for P2704 range from $150 to $6,500, depending on the vehicle and root cause.
