Have anyone else had any serious problems with their Automatic Powershift gearbox?

After only 63900 miles my 2014 V40 is indicating “Transmission Reduced performance” (limp mode) and the TCM is indicating the trouble code P284B: Shift Fork 3 blocked/stuck.
An authorised Volvo Service changed Oil and filter in December at 51780 miles

I don’t understand how a gearbox can cause trouble so early. I’ve learned that the MPS6 gearboxes are among the worse on the market and comes from Ford. However I’m surprised that I can’t find many posts on the forum with similar issues (only one).

Anyone heard or have any experience?

Is this so serious so the gearbox has to be replaced? Or is it a reprogram of the TCM controller? Cleaning the indicators? The box have never felt bad or it doesn’t sound or feel bad when driving it in limp mode (gears 1-3).

Thanks
