I’m glad I found this thread, been having the same symptoms as the OP
cuemark8 as well as others in this thread
Millennium XL-200 &
DaCoupe
What was the final verdict for the others, it seems that
Millennium XL-200 has had his transmission replaced, but what about the others?
I am experiencing the same problems, supercharger/whining sound when clutch is engaged (pedal not pressed) and no more sound when the clutch is not engaged (pedal is pressed in). I did take it to my dealer, and they acknowledge the sound, and was advised it wasn’t a first time that this happened on a “manual fiesta” and a first fix they will be trying on my Fiesta is changing out the transmission oil, for fresh oil; this supposedly eliminated some of the sound as per my service advisor, but it is still present, will see this evening when I pick up the car and tomorrow morning at a cold start-up.
My dealer did tell me that on the previous Fiesta they worked on with the same problems, they had replaced literally everything in the transmission and there was still a bit of a sound to it, which they deemed normal after the fact. I will not be accepting this as a final results, and if push comes to serve, I will request a new transmission altogether.
For those that have not had their transmission changed, is the sound still present, did you transmission blow up on you? What did you do?
Thanks,
JP
