Been having an issue with the car where the transmission is very noisy and make a very noticeable rattling sound when hot. It also struggles when going up any kind of incline. On steep hills it bogs down quite a bit and seems to have no power. When car is cold there are no issues. With the days slowly getting warmer this will be more of an issue and I need to have some idea of what I might be looking at. As a side note, I do have to change the crank position sensor. Could this be related?
