P0730 on Ford by model: symptoms, diagnosis and fix
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.
Common Symptoms
- Violent shuddering or juddering when accelerating from a stop
- Transmission hesitates or refuses to move in Drive for 1-3 seconds
- Unexpected lurch forward when releasing brakes at low speed
- Grinding or clunking between gear changes
- Transmission surging and jerking during low-speed driving
- Vehicle bucks and shakes at 15-35 mph (clutch slip zone)
- Transmission warning light or "Transmission Fault" message
- Loss of drive in one or both gears
- Delayed engagement from Park to Drive
How to Fix
Check fordtransmissionsettlement.com for class action settlement eligibility. Ford's warranty extended to cover repeated repairs. Updated clutch service parts: Focus uses F1FZ-7B546-B clutch (replaces BV6Z-7B546-F). TCM repair/replacement per TSB 16-0109. Software recalibration via IDS tool at dealer. For definitive fix: remanufactured DPS6 transmission. Many owners chose to pursue buyback via state Lemon Laws. Latest settlements include 2017-2018 models under separate class action.

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.
Common Symptoms
- Grinding noise when shifting into 2nd or 3rd gear
- Difficulty shifting when transmission is cold
- Notchy or stiff shifter feel
- Gear lockout at high RPM
- Popping out of gear
- Clutch chatter or judder
How to Fix
Ford has released multiple TSBs including TSB 11-3-18 recommending lower viscosity transmission fluid for cold shift issues. Replacing OEM fluid with Motorcraft XT-M5-QS or aftermarket fluid like Royal Purple Synchromax can help. Severe cases may require synchronizer replacement ($800-1,500) or full transmission rebuild/replacement ($2,500-4,500). Some owners opt for aftermarket transmissions like the Tremec Magnum ($4,000-6,000 installed).

Complaints show a recurring pattern of automatic transmission failure on early Escapes, including harsh shifting, no movement in Drive, slipping, grinding, and in severe cases unexpected gear changes. Some owners report the transmission suddenly shifting abnormally at highway speed or losing the ability to stay in Park, creating both drivability and rollaway concerns.
Common Symptoms
- Vehicle will not move in Drive
- Harsh or incorrect shifting
- Grinding noise from front/transmission area
- Transmission slips or changes gears unexpectedly
- Vehicle will not stay in Park
How to Fix
Diagnosis should include checking transmission fluid condition, shift cable/bushing integrity, range selector operation, and internal transmission damage. Repairs range from replacing the shift cable bushing or linkage to a full transmission rebuild/replacement if there is internal gear or clutch failure. Costs typically run from $100-$350 for linkage repairs up to $2,500-$4,500 for a remanufactured transmission installation.

The conventional gasoline Escape (2020+) uses the 8F35 eight-speed automatic. Early units have output planet-carrier needle bearings that were not adequately hardened; when they fail they shatter, causing the carrier to overheat, shed metal, and grind itself apart — fluid turns silver, the SUV slips under light load, then clunks or grinds. Separately, a powertrain-control-module software calibration causes a shudder/buck/jerk at speeds up to about 35 mph that owners frequently report. Many owners experience harsh engagement, slipping, and eventual transmission replacement. This is distinct from the 2020+ hybrid CVT (eCVT) shudder already documented — it is the conventional 8-speed automatic in gas (1.5L/2.0L EcoBoost) Escapes.
Common Symptoms
- Shudder, buck, or jerk while accelerating up to ~35 mph
- Harsh or delayed shifts and slipping under light load
- Grinding or clunking noise from the transmission
- Silver/metallic-colored transmission fluid
- Revs in Reverse but vehicle does not move
How to Fix
For the low-speed shudder/buck, Ford issued TSB guidance (e.g., 8F35 shudder/buck/jerk bulletin) calling for a PCM reprogram and, if needed, transmission service. For needle-bearing failure (covered by TSB 22-2281 for 2019-2021 units built before late 2021), the fix is overhaul/replacement of the transmission including the planetary gearset. Out-of-warranty transmission overhaul or replacement typically runs roughly $3,500-$6,000; a PCM reflash for the shudder is usually a low-cost dealer service.

The 2020+ Ford Escape Hybrid uses a CVT that develops shuddering and jerking during low-speed driving and light acceleration. Owners report the transmission feels like it is "hunting" for the right ratio, with noticeable hesitation between 15-35 mph. The issue is most pronounced in stop-and-go traffic and when transitioning between electric and gas power. Some vehicles have had the transmission replaced under warranty.
Common Symptoms
- Shuddering at 15-35 mph
- Jerking during light acceleration
- Hesitation when accelerating from stop
- RPM flare without corresponding acceleration
- Clunking when shifting from park to drive
How to Fix
Have the dealer perform a TCM (Transmission Control Module) software update first, as Ford has released calibration updates that improve shift quality. If the software update does not resolve the issue, a CVT fluid change may help. Persistent cases may require valve body or full transmission replacement under the powertrain warranty ($4,000-6,000 out of warranty).

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.
Common Symptoms
- Brown fluid puddle under vehicle near front axle area (PTU fluid is brown/gear oil)
- Grinding, howling, or whining noise from drivetrain
- Vibration during acceleration, especially from stops
- AWD malfunction warning light
- Burning gear oil smell
- Low fluid level in PTU (check port on PTU body)
- Clunking on hard acceleration
How to Fix
Replace PTU axle shaft seal kit (Ford seal kit includes intermediate shaft seal, alignment washer, deflector, and seal protector tool). Complete PTU rebuild or replacement if run dry. Proactive maintenance: change PTU fluid every 30,000-40,000 miles using Ford-spec fluid (Motorcraft MERCON LV or Ford WSS-M2C938-A). PTU fluid capacity is approximately 0.5-0.8 quarts depending on year.

Frequently asked questions
What does P0730 mean on a Ford?
P0730 stands for "Incorrect Gear Ratio." This code means the transmission computer detected that the actual gear ratio (calculated from input vs. output shaft speeds) does not match what it should be for the commanded gear. In other words, the transmission isn't delivering the correct gear, which often shows up as slipping, flaring RPM during shifts, or being stuck in the wrong gear. It can stem from internal mechanical wear, low or contaminated fluid, or faulty solenoids and sensors. The vehicle may shift harshly or enter limp mode. On Ford it is documented across 9 models: Focus, Mustang, Escape, Edge, Maverick, Bronco, Fusion, Explorer, F-150.
What are the most common causes of P0730?
The most common causes of P0730 are: Low or contaminated transmission fluid, Worn clutches or bands (internal slipping), Faulty shift solenoids, Dirty or sticking valve body, Faulty input or output speed sensor, Internal hydraulic/line pressure problems, Torque converter problems, General high-mileage transmission wear. The specific cause varies by vehicle.
How much does it cost to fix P0730 on a Ford?
Published repair estimates on Ford range from $100 to $6,500 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.
