2014 Ford Fiesta: harsh or hard shifting

Filed Jul 7, 2025 · Transmission · NC

Vehicle presented to A&T Auto Repair with rotation-dependent clunking sound. This clunking started after loud metallic snapping noise occurred while coasting in gear on a flat surface. Mechanic noted that clunking noise came from the transaxle. Once the transmission fluid was drained, metallic grit and large chunks resembling gear teeth were found in fluid. A replacement transaxle was installed, along with a new "clutch kit" containing flywheel, pressure plate, and slave cylinder. Following installation and engine start up, slave cylinder leaked, prompting the order of new parts and replacement labor. According to Mechanic, four different slave cylinders from two separate manufacturers leaked in the same fashion upon engine startup, due to a "locking" malfunction of the slave cylinder. The recurrent nature of the parts failure seems to indicate a deficiency in part design that causes a fluid leak, possibly endangering driver and passengers in the event of a transmission failure.

I am the original owner of my 2014 ford fiesta s hatchback. The vehicle has a 5-speed manual transmission and 33350 miles +/- on it. I have two issues with the car: 1) the second and reverse gears (only) have "popped" out numerous times under torque. This occurs only when decelerating, accelerating, and occasionally while reversing slowly out of the garage etc. The latest event was december 29, 2016 travelling down a short road. The second gear popped out and the vehicle immediately began to accelerate toward the embankment. Each event surprises and frightens me until I realize what has occurred and respond accordingly. 2) the second issue is something is producing a clunking in the lr pillar (between the lr passenger door and the hatchback). Or so I imagine. It sounds like a hatch strut is hanging loose from the top connection and swinging around inside the hollow of the pillar. However, both hatch struts are fully accounted for and appear to be attached as designed. The noise is ongoing and coincides with vehicle motion, especially on curves and rough ground.

My car surges forward almost squealing tires, it makes noise it clunks out at stop feels like my tranny is going to drop and doesn't shift correctly. Transmission is obviously in safe I am afraid I am going to hit someone from behind the way it surges at times it also sputters and moves down hill when stopped drags when driving up hill. I had to take it in they replaced modular and tranny seal. But it still happens.

This 2014 ford fiesta vehicle has some major transmission issues: slipping, clunking, chugging, jerking, shuttering, and rattling when doing something as simple as pressing the gas pedal to accelerate when a traffic light turns green. This issue also occurs when I begin to come to a complete stop. I've only had the car for about five months and the issues have occurred throughout that time period. I have taken this vehicle to a ford repair shop. The mechanic completed a reprogramming of some type. He informed me that the reprogramming typically resolves the issues that this vehicle is having; but the issues still remain, in fact, it's gotten worse. The hesitation of this vehicle to accelerate leaves me feeling unsafe. Motorists in passing vehicles are zooming by me as I am attempting to get this car to go. In addition, when I firmly press the gas petal, the car hesitates then begins to accelerate at a rapid speed. These issues occur while I am driving on the interstates, highways, streets, dirt roads, etc. It also does not matter if I am making a turn, shifting in drive or in reverse...the issues remain the same. Ford needs to be held accountable for these issues. It is terrible that they would not be concerned about the safety of their consumers. These safety issues were not mentioned on the carfax report. If they had been then I would not have purchased this vehicle.

Problem is the transmission failed to engage when I pressed on the gas petal to go, it took almost a full second after pressing the accelerator, I would estimate, before the transmission would engage into 1st gear. I have had it happen before to a lesser extent, all randomly, so I never know when it will or won't go when I press on the gas petal. Very dangerous if you need to cross traffic and the car just sits there then decides to shoot you out into oncoming traffic. I also had problems with shuddering at low speeds, and hard shifting from 4th to 5th gear.

This vehicle has a transmission that causes bucking, kicking, jerking, harsh engagement, rough shifts, shuddering, delayed acceleration, red-lining prior to shifting, and feeling like it is returning to neutral during stop. This issue has been turned over to the dealer service center and ford motor service. Both claim there is a clutch isse that is not a life safety issue and will not damage the vehicle long term. Both claim the parts are on back order and should be installed in 3-8 months.

I've brought the vehicle to ford dealership service departments several times now for the same transmission shuddering and slipping issue. When taking delivery of the vehicle, and on every subsequent visit to a service department, I was warned that the powershift 6-speed automated manual transmission requires a "break-in" period of several thousand miles and that I may notice harsh shifting or noises. In reality, the transmission hasn't ever functioned correctly, and on each dealership trip, a lets-try-the-next-step approach is taken. First a engine malfunction indicator lamp was cleared for a known firmware bug in the transmission control module (TCM), for a problem whose fix was not yet released by ford. Next, the TCM was updated. Driveability improved for a while but then degraded again, getting worse day by day. Next, the TCM couldn't be updated (it was already up to date) so a new clutch assembly was ordered. Finally, the clutch assembly was replaced, but not the transmission intake seals because they were brown (latest spec?). It has only been a few days since the most recent repair (clutch replacement) but the dealership advised that the new clutches will eventually fail in exactly the same way as ford has not yet corrected the underlying issue. When the vehicle shudders during acceleration, there is an increased risk of an accident from oncoming cars (while making a left turn) or from cars behind me.
