The Ford A4LD 4-speed automatic transmission used in early Aerostars (and the 4R44E/4R55E in later models) is known as one of Ford's weakest automatic transmissions. The overdrive band and servo fail prematurely, causing loss of overdrive. The forward clutch pack also wears rapidly, causing no-drive conditions. The valve body develops wear in the separator plate, causing erratic shifting. The transmission was originally designed for the lighter Ranger and is marginal for the heavier Aerostar, especially the AWD version.

The 10R60 automatic transmission may exhibit harsh or delayed engagement when shifting, particularly from park to reverse when cold. Some vehicles skip gears during deceleration around 28 mph causing lurching.

The Getrag MT88 7-speed manual transmission exhibits rotational scraping or grinding noises, particularly in cold temperatures below 50°F. The noise occurs in neutral, 1st, and 2nd gears with clutch engaged and may diminish as transmission warms up. Issue traced to 5th and 6th gear synchronizer rings.

AWD-equipped 2021-2024 Ford Bronco Sport models exhibit rear drive unit (RDU) chatter and shudder during low-speed turning maneuvers, particularly when backing up and turning sharply. The issue is caused by fluid contamination in the rear drive unit's limited-slip clutch pack. Ford issued SSM 49571 (Special Service Message) documenting the condition as "chatter/shudder during low speed turning events." Multiple TSBs have been released addressing the issue, with the prescribed fix involving draining and refilling the RDU fluid, then performing specific drive cycles with controlled turns. No formal NHTSA recall has been issued for this defect. BroncoSportForum.com has an extended thread specifically about new rear axle assembly replacements covered under this TSM.

The hybrid eCVT transmission can develop a shudder or vibration during acceleration, particularly when transitioning between electric and gas power. Often related to degraded transmission fluid or worn clutch packs in the power-split device.

The CD4E automatic transmission used in the Contour is one of the most failure-prone transmissions Ford has produced. The forward clutch pack, servo bore, and torque converter clutch are common failure points.

The Power Transfer Unit (PTU) on AWD Ford Edge models is known for chronic fluid leaks from the axle shaft seals and PTU cover seal. The PTU (transfer case equivalent) lacks a drain plug and Ford originally specified "lifetime fill" fluid, leading many owners to never service it. When the seal leaks and fluid level drops, the PTU runs dry and destroys itself. Ford issued TSB 09-25-7 for 2007-2010 models, and the issue persists through 2018 with TSB 18-2255 for later versions. Seal failure typically occurs between 60,000-100,000 miles and is common in AWD models. A destroyed PTU can also damage the rear axle and differential.

The CD4E automatic transmission used in the Escort is known for premature failure, particularly the forward clutch piston and servo bore wear. Symptoms progressively worsen over time.

The 10-speed 10R80 automatic transmission in 2018+ Expeditions develops a torque converter shudder during light acceleration between 35-55 mph. The shudder feels like driving over rumble strips and is caused by the torque converter lockup clutch slipping. The 10R80 aggressively locks the torque converter at low speeds for fuel efficiency, which accelerates clutch material wear. Contaminated transmission fluid from degraded clutch material worsens the shudder over time.

The 10R60 10-speed automatic transmission exhibits harsh shifting, delayed gear engagement, slipping between gears, and erratic behavior. Ford identified that actuators in the transmission are sometimes too tight, causing abnormal shifts. The transmission adaptive learning can also cause issues when it incorrectly learns driving patterns.

The 2011+ transverse Explorer switched to the 6F50/6F55 six-speed automatic, which is widely reported for a sluggish 0-5 mph roll-out followed by a harsh 'bump' or clunk, plus torque-converter shudder and occasional shift flare. Ford addressed the low-speed bump with TSB 11-12-10 and the sluggish-acceleration-then-harsh-bump pattern with TSB 13-3-18, both calling for a PCM/TCM reflash; check-ball and separator-plate revisions were also used. Higher-mileage units can develop internal clutch/drum wear and lose 3rd/5th or reverse.

The 10R80 10-speed automatic transmission can develop a shudder during light acceleration, typically between 25-50 mph. This is caused by torque converter clutch issues and affects many F-150s. Ford has released multiple TSBs and fluid updates to address this.

The DPS6 PowerShift 6-speed dual-clutch automated transmission fitted to 2012-2018 Ford Focus (and 2011-2019 Fiesta) is widely considered one of the worst transmission designs in modern automotive history. The dry dual-clutch design was fundamentally unsuited for stop-and-go driving, producing violent shuddering during low-speed acceleration, hesitation when pulling away from stops, unexpected surging, and abrupt harsh shifts. Ford knew of the defects from the start but concealed them and continued selling vehicles. Multiple class action lawsuits resulted in settlements covering 2012-2016 models (expanded to 2017-2018). Ford issued dozens of TSBs and software reflashes that repeatedly failed to fix the underlying mechanical problem. The TCM (Transmission Control Module) failures are a distinct but related issue. Repair options include clutch replacement (temporary fix), TCM reprogramming, or complete transmission replacement.

The Freestar's AX4S 4-speed automatic transmission develops torque converter shudder during light acceleration at 35-50 mph. The converter clutch lining disintegrates, contaminating the fluid with debris that damages the valve body and solenoids.

The Freestar inherited many of the Windstar transmission problems. The torque converter develops shudder during light acceleration, and the transmission can fail completely with forward clutch pack burn-up.

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.

The MT82 6-speed manual transmission is notorious for multiple issues including gear grinding (especially 1st to 2nd and into 3rd gear when cold), high RPM lockout preventing shifts, notchy/difficult shifts, premature synchronizer wear, and in severe cases complete transmission failure. The transmission was originally designed for smaller four-cylinder vehicles and the synchronizers struggle to handle the Mustang's higher horsepower.

The 10R80 10-speed automatic transmission exhibits issues including harsh or jerky shifting, gear hunting (constantly searching for the right gear), hesitation during acceleration, unexpected downshifts, and transmission whining. The transmission's aluminum outer shells can develop divots where clutches stick, causing erratic shifts. Multiple class-action lawsuits have been filed.

The 10R80 10-speed automatic transmission can develop a shudder during light acceleration, typically between 25-50 mph. Harsh or unpredictable shifts can also occur. This is the same transmission used in F-150s and has similar issues.

The AX4S and later AX4N automatic transmissions used in the Taurus are prone to premature failure due to torque converter clutch issues, valve body wear, and overheating. Common in high-mileage vehicles and those used for frequent stop-and-go driving.

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.

The Ford Windstar equipped with the AX4S (1995-2000) and AX4N/4F50N (2001-2003) automatic transmissions suffers from widespread premature transmission failure. CarComplaints.com records 140 complaints for the 2000 model year alone, and 166 problems for the 2003 model year, making transmission failure the single most reported problem for the Windstar. The AX family of transmissions in the Windstar struggles with lubrication problems, harsh 1-2 and 2-1 gear changes, torque converter clutch issues, and catastrophic internal failures. The torque converter clutch solenoid is a particularly weak point, causing shuddering and codes P0741 and P1744. Average repair cost is $2,190 at 102,200 miles according to CarComplaints.com data. Many owners report needing a complete transmission replacement or rebuild, with costs ranging from $1,750 to $3,100.
