DTC code TCM-0350

[yoyon]

Hello,

Recently my 2004 xc90 t6 awd had a message in dash "Transmission Service Required", the message appeared when I was at manual shift mode in 2nd gear on downhill road to use 2nd gear as an engine break.

Shortly I scanned with vida, I got DTC code TCM-0350 which is meant Wrong Type of Transmission (???).

The first time I did was resetting with vida to clear the dtc, but failed. Still got the message "Transmission Service Required".

My xc90 never changed transmission since new. Transmission Oil always change every 30000 miles with filter replacement.

Do you have an experience like this? What should I do?

Any help will be appreciated.

Thanks
