P0730 on Ford vehicles indicates incorrect gear ratio. Au7o has documented this code across 6 Ford models — most commonly on Bronco, Edge, Escape. 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. Typical repair costs on Ford range from $150 to $6,500, depending on the specific model and root cause.

Common Causes of P0730

  • •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

P0730 on Ford by Model

Ford Bronco(1 issue)

  • 7-Speed Manual Transmission Grinding/Scraping Noise2021-2023

    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.

Ford Edge(1 issue)

  • Power Transfer Unit (PTU) Fluid Leak and Failure - AWD Models2007-2018

    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.

Ford Escape(1 issue)

  • CVT Transmission Shudder and Jerking (2020+ Hybrid)2020-2025

    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.

Ford Focus(1 issue)

  • DPS6 PowerShift Dual-Clutch Transmission Shudder, Hesitation, and Failure2012-2018

    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.

Ford Maverick(2 issues)

  • Hybrid eCVT Transmission Shudder and Delayed Engagement2022-2025

    The 2022-2025 Ford Maverick Hybrid with the 2.5L Atkinson-cycle engine and eCVT (electronic continuously variable transmission) experiences intermittent shuddering, delayed engagement from stop, and unexpected transmission behavior. MaverickTruckClub.com documents cases of the transmission refusing to move from a stop, shuddering under light acceleration, and lunging forward after a delay. Some owners report that the truck will not move when cold, then lurches when pressed on the gas. While the Ford eCVT is based on proven Toyota Prius-style planetary gear set technology and is generally reliable, the tuning and calibration for the Maverick application has produced drivability complaints. Ford has issued software updates to address some of the calibration issues. Complete transmission failures have been reported at MaverickTruckClub.com, though they appear to be relatively uncommon compared to the shudder/hesitation complaints.

  • 8F35 Transmission Shudder/Buck/Jerk Below 35 mph and Output Carrier Bearing Wear (Early 2022 Builds)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.

Ford Mustang(1 issue)

  • MT82 Manual Transmission Grinding and Shifting Issues2015-2023

    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.

Frequently Asked Questions

What does P0730 mean on Ford?▼
