Recently, my car started jerking when the drive stick is shifted from 'R' to 'D' position. This doesn't happen when shifting between other positions (not even D to R) or when I switch between gears just after starting the vehicle.
For example, after reversing the vehicle and then when I'm shifting to 'D' to start driving, it starts the forward motion with a jerk, like the vehicle tripped over something.
I have consulted the local Toyota dealer, and their approach is to replace the entire gear box. Since it's costly, I'm wondering whether this can be fixed by replacing only few particular parts. Contacted few individual mechanics, but would like to know from anyone's experience what's the issue and potential fix. So, I will have some sort of understanding on what's going on.
Note: Car is a 2007 manufactured Toyota Belta. Has a mileage around 110,000 Km.
