I have a td 6 speed manual d40. I have been having problems getting it into first gear. When the car is not moving just sitting at idle, when i try to push it into gear it is really hard and takes a couple of tries before it will go into gear. It doesn't make any grinding noise. but if the car is rolling it seems to just slip straight into gear and all the other gears are fine. It happens on and off its not all the time and it doesn't matter what the temperature of the day is it just does it when it feels like it. has anyone had this problem or know whats causing it.
