In some cases, the problem is within TCU itself.As a result, TCU cannot handle rapid gear changes. The root of this problem is within the clutch material, which sometimes overheats under load.As it led to various class-action lawsuits, Ford extended its warranties on this issue in many countries. This well-known problem affected many cars made from 2010 to 2017.Both can be safety issues, affecting acceleration and overall vehicle performance. This can also be accompanied by downshifting issues, meaning the vehicle will remain in a higher gear. When accelerating fast in cars with Powershift dual-clutch automated transmissions, there can be a slipping sensation or shaking followed by audible noise. Incorrect shifting and slipping during acceleration or deceleration Check transmission fluid level and top-up or replace it if needed.If this is the case, no further repairs are needed. Sometimes installing the latest TCM calibration update and resetting adaptive learning parameters can make shifts smooth.Adjusting your driving style to match others can solve the issue. The harsh shifting happens in scenarios where several persons with different driving habits use the same vehicle. All six-speed transmissions have highly adaptable shift calibrations, which ‘learn’ and adapt their shift patterns based on the driving style.This will be an occasional issue for most drivers, and there will be no other apparent symptoms. In most cases, this will be most noticeable during upshifts or downshifts between 3th and 4th gear. Check the Output speed sensor wiring and connector for damage or loose play.Īll vehicles with any variant of six-speed automatic transmission can suffer from harsh shifting.Contact your authorized Ford dealer to see if your vehicle is affected. In most cases, this is covered by a safety recall 19V-075. Many of these transmissions have an issue with a faulty Output Speed Sensor (OSS), which occasionally sends an incorrect signal to the TCU.Sometimes, this will trigger a check engine light, which means a code will be stored in Powertrain Module memory. This happens in any gear in most cases, there will be no apparent pattern. Sudden downshift to 1st gear.Īll Ford vehicles with a 6R80 6-speed automatic transmission can develop an issue with sudden and unintended downshifts to 1st gear. Sticking or leaking Variable Camshaft Timing (VCT) solenoid can cause similar issues, so rule out. Replacing them with upgraded ones solves the problem. This happens because this transmission was the first one to use rubber check balls instead of steel ones. Valve body check balls, which ensure transmission fluid flows into the right chambers, wear out prematurely.Sometimes it will show up as a lack of acceleration only in second gear or unusually fast gear shifts.Īnother common symptom is stalling when coming to a stop. Troubleshooting by Symptoms Low Power Stalling and Quick Shiftingįord trucks with a 4R70E or 4R75E 4-speed automatic transmission can develop several gear shift issues. Select Read Fault Codes from the main menu.Select Control Units, then Transmission or PCM Module.Allow it to communicate with the vehicle. Plugin your OBD-II scanner, then turn on the ignition without starting the engine.Locate the diagnostic port under the dashboard, driver’s side.Park the vehicle and turn off the ignition-set parking brakes.You will also learn to read Ford transmission fault codes using a Ford OBD-II Scanner. The YOUCANIC Full System Scanner can read and clear fault codes through every vehicle’s control module. For more help, see our guide on choosing the best scanner for Ford. Note that generic OBD-II scanners can only read codes related to the check engine light, not transmission codes. To diagnose Ford’s automatic transmission problems, read the fault codes with a Ford Transmission Scanner. The good news is that most Ford transmission problems are detected by the Transmission Control Module (TCM), where fault codes are stored and retrieved with the right scanner. Troubleshooting Ford Transmission Problems Certain Ford models equipped with the PowerShift dual-clutch automatic transmission, such as Ford Fiesta and Ford Focus, have issues such as erratic shifting, transmission drops in neutral, or lack of acceleration. Troubleshooting Ford Transmission Problemsįord automatic transmission problems are caused due to low transmission fluid.
