Hello, I am new here and I would like to share this topic with you as I might find some guidance and advice. as I was driving I got the notification of “Gear malfunction” no reverse gear ( you can continue driving). The car started to become heavy as the gear is not changing and I had to drive very very slowly on the first gear only (no gear changing). The car dealer’s garage checked the car and the feed back was that the computer of the gear needs to be changed! is this problem common?!
