P0741 on Ford: How to Diagnose & Fix

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 to address related concerns, including PCM reprogramming for harsh shifts (TSB 18-2274) and main control valve body replacement for a sticking torque converter clutch valve (TSB 20-2117).

The 4R70W (and later 4R75W/4R75E) 4-speed automatic behind the 4.2L V6 and 4.6L/5.4L V8s is prone to several high-mileage failures: a broken reverse (cast) band that produces a loud POP and loss of reverse; a cracked forward-clutch drum snap-ring groove on 2005+ units causing loss of ALL forward gears while reverse still works; worn overdrive band and clutches causing slipping; and solenoid-body/servo wear causing harsh or erratic shifts. Failures accelerate under towing/heavy loads and when fluid changes are neglected.

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 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 Ford issued Technical Service Bulletin 22-2281 (since superseded by 24-2092 and 25-2550) for 2019-2022 Transit Connect vehicles built on or before July 1, 2022 with the 8F35 transmission, addressing slipping, harsh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.

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 electronically controlled E4OD 4-speed automatic behind the V8s is notorious for failing, especially with age, towing, off-road use, or an undersized/overheated cooler. It is heat-sensitive, and a well-documented secondary killer is the brake-light circuit: the PCM watches brake-light voltage to unlock the torque converter, so a shorted/failed brake light, brake-switch wiring, four-way flasher activity, or non-resistive LED bulb swap can make the converter cycle improperly and burn up the transmission. Owners also report the O/D-off light flashing (stored fault), harsh or missing shifts, and failure to shift out of high range from a lost power feed.

The Ford A4LD 4-speed automatic transmission used in early Aerostars (and the 4R44E/4R55E in 1995-1996 and the 5R55E on the 1997 4.0L) 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.

P0741 indicates the PCM has detected a torque converter clutch performance fault. Ford TSB 19-2100 (April 2019) states that some 2013–2015 Escape vehicles with the 1.6L EcoBoost engine may show an illuminated MIL and/or a transmission malfunction service now warning with only P0741 and/or P1744 stored, and that this may be due to internal damage to the torque converter. The bulletin applies only when all of those criteria are met; other engines, years or additional codes need their own diagnosis.

The 6F35 six-speed automatic is prone to harsh, banging, or delayed shifts (most often 2-3 and 3-4) plus a shudder/vibration when the torque converter clutch locks up at a steady 40-60 mph cruise. Root causes are worn valve-body separator-plate O-rings and bores that can no longer hold clean line pressure, clogged/worn shift solenoids, and torque-converter clutch degradation. Many units develop symptoms well before 100,000 miles. A 2021 class-action lawsuit (Gant v. Ford) accused Ford of concealing the 6F35 defect on the Fusion; the cited December 2024 report says the suit was dismissed.

Owners report a shudder or vibration that feels like driving over rumble strips, typically in 3rd through 6th gear at light throttle or on gentle inclines - exactly when the transmission control module tries to hold the torque converter clutch in partial (EMCC) lockup. FORScan logging shows the TCM commanding roughly 20 RPM of converter slip while actual slip wanders randomly between 0 and 200 RPM, which is the signature of a glazing converter clutch lining or a TCC/pressure control solenoid that has been contaminated by clutch material and metal debris. Because the shudder mimics an engine misfire, many owners chase spark plugs, coils and motor mounts first. Left alone, the debris circulates through the valve body and takes out other solenoids and eventually the transmission.

The 5R110W TorqShift automatic behind the 6.0L and 6.4L Power Stroke diesels and the 6.8L V10 in Super Duty trucks is a strong unit, but its stamped-steel torque converter with a single-disc lockup clutch is the weak link. Heat from towing, added horsepower, or fluid that was never changed cooks the lockup clutch lining. When the converter fails it does not fail cleanly - it sends clutch material and steel debris through the entire transmission, contaminating the valve body, the shift solenoids and the cooler circuit, so a converter failure typically takes the transmission with it. Owners first notice a shudder or vibration at lockup speeds, then harsh or erratic 3-4 and 4-5 shifts, then slipping. Solenoid faults and hard shifts on these trucks are frequently the downstream symptom of debris rather than an independent problem.

The 4R100 four-speed automatic fitted to 1999-2003 F-350s behind the 7.3L Power Stroke is the weak link in an otherwise durable driveline, and F-350 duty cycles - fifth-wheel and gooseneck towing near a 20,000 lb-plus combined weight - expose it. Two failure patterns dominate owner reports. First, on early 2001 units (roughly the first six months of production) Ford used a mechanical diode one-way clutch on the direct drum in place of the roller sprag; when the diode seizes the truck can lurch and skid the rear wheels on the shift into third, and Ford went back to a roller sprag. Second, the torque converter and the undersized factory cooler let fluid temperatures climb during towing, cooking the clutch packs and sending debris through the valve body and pump. A Ford TSB (02-21-1) also documents the torque converter external access dust plug falling out under severe-duty use, allowing fluid loss.

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 sluggish-acceleration-then-harsh-bump pattern on early-build 2011 Explorers with TSB 11-5-6, which calls for a new PCM/TCM calibration plus transmission valve body changes (separator-plate and check-ball revisions). Higher-mileage units can develop internal clutch/drum wear and lose 3rd/5th or reverse.

The 4-speed automatics behind the 4.0L - the early A4LD and the later electronically controlled 4R55E - are a known weak point, commonly failing in the 120k-mile range, most often losing 4th gear (overdrive). The overdrive planetary is fragile (early units used a weaker pinion design, later updated to a 6-pinion gear), and a failing vacuum modulator on the A4LD can quietly cook the overdrive section. When the overdrive sprag or drum lets go, debris circulates and a full rebuild is required. A closely related driveline failure is the powdered-metal spacer between the crankshaft and flexplate: Ford's sintered spacer is brittle and cracks, causing a rattle, vibration, and eventually hard-start/no-start or driveline separation.

The Freestar inherited many of the Windstar transmission problems. The torque converter develops shudder during light acceleration, and on 2004-2005 vans the torque converter pump shaft splines can wear and fail without warning, causing a sudden loss of drive (recall 12V-006 / Ford 11S25).

The 8F35 eight-speed replaced the 6F35 in the Edge for 2019. Ford bulletin 21-2081 covers 2019-2021 Edges with the 8F35 built on or before March 11, 2021 that may shudder, buck or jerk while driving up to 35 mph, attributing the condition to PCM software and correcting it by reprogramming the PCM and transmission solenoid strategy. This is separate from the 6F35 harsh-shift complaint on earlier Edges.
