I have a problem just like that but in first and reverse, I barely goes into first gear after I have stopped but will go into first when it is cold. But it hardly ever goes into reverse, only when the engine is turned off it will go into reverse. Took it into the dealership and they tried it in reverse when the car was off. I am just going to have to bring it into the dealership again.
Thanks guys for bringing up the topic, never thought about it when the car was running.
