Ford Fiesta SE 2015
Hello hello everyone. I have a Ford Fiest SE 2015 and I love love it. It's been problem free until recently. I hope someone can provide insight.

On three occasions when starting the vehicle and shifting into Reverse, I receive a ‘Transmission failure. Service Immediately. OK’ error message. I clear the error, i.e., push "ok" button and the vehicle will no longer reverse that is move backwards. I turn off the vehicle, restart it but the error message reappears, when I put the gear selector into Reverse. However, the vehicle will drive forward when I put the gear shifter into Drive.

On all three occasions, I have been able to get my vehicle to be able move in reverse after I do the following. Put the vehicle into Neutral, push it back 2-3 yards. Start the vehicle, put the gear shifter into Reverse and it moves backwards. I put the gear shifter into Drive, and it moves forward. No error messages.

I have driven the car several hundred miles in-between receiving and “fixing” the ‘Transmission failure.’ warnings with no issues. It drives and shifts brilliantly. Another troubleshooting step: Checked for error codes but my reader will not link.

Note, I did have Ford investigate and fix the “clutch shudder” recall in 2019.

Have you ever heard of a situation like this? I do not want to take it to Ford Dealership, without having more information.

Regards

Have you had to jump start your fiesta recently? Maybe left something turned on and ran the battery flat dead? It sounds like a power supply issue. Maybe the battery has an internal short or you need to check the condition of the grounds from the powertrain control. If the transmission has the current updates i would be looking at the areas i mentioned.

Odd issue, - but if the shifter is working - placing the vehicle in Neutral to coast it backwards so it can find reverse gear...

That sounds like a TCM (Transmission Control Module) near imminent failure.

IT can't make the solenoid do it - you have to place the gearbox in free-wheeling mode (Neutral) means that TCM may have a power problem as it can't get enough energy into the solenoids to make it shift into reverse - you can manually do that to "line up" that gearbox to do it so the parking pawl to Reverse can occur.

So this can be two things, too much torque on the Parking pawl - from being left on an incline and now the stress of weight of the rolling load onto the pawl is enough to prevent the transmission from shifting out of park - but you're able to put in in neutral - the issue may be with more of the shifter assembly PHYSICAL alignment to its ELECTRICAL alignment - because the mechanical of the shifter still affects the transmissions gear selection and the solenoids then follow the selector to know what gear range of Reverse or Drive / Low or Park / Neutral to use.

Definitely needs a look see - Dealer? well, that may be the only option.

Thank you for your response. I haven't had to jump start my Fiesta this year. I did put in a new battery earlier (February) this year. A common occurrence in Phoenix. Everything "electrical" seems fine...radio is staticky though. I always make certain to turn off everything I can e.g., radio, lights, AC...etc.

Thank you for your response. I am not automotive savvy, so I'll go the Ford Dealer. I am concerned it'll be a game of "whack-a-mole" with them costing BIG $$$ until it gets resolved.

When this transmission failure Service immediately message comes up...

I wonder if the dealership can help you in re-align the shift lever to the TCM shift "expected"

As in there may be a sensor in the transmission shift lever in the car, that tells the TCM to "go here".

Ok, if it's a dirty switch or the TCM is not getting enough voltage to send the transmission the correct shift location - then this failure occurs, it can be from poor battery grounding, a sensor wire - or the grounds between the engine and frame grounds are not equal, so the TCM sees a floating voltage - which changes - that upsets the TCM - it thinks it should be here, but the shift lever to control - due to its low voltage, poor connection issue - tells it something else - the system waits a moment but if it can't settle down, this shift failure causes that service message.
