Whenever my 2004 Honda Pilot gets stuck in traffic, I have to switch it into a lower gear in order to resume forward. Automatic transmission. It’s a rebuilt trans that has 60K on it. Transmission fluids at right levels and recently flushed. The car mileage is 198K. I don’t have the issue with normal highway and local driving. It is only when I am stuck in traffic. Several shops investigated, but no codes come up on computer, and no answers. Any suggestions?
Did anyone check the torque converter oil level / pressure when idling? Perhaps it isn’t getting the proper flow of tranny fluid in stop and go traffic (because you are coasting and idling in stop and go traffic ) When you shift gears, perhaps fluid is being forced into the torque converter?
