I have a ticking noise from the car. It sounds like a lifter ticking but, the shop says it is coming from the transmission area. They believe it is the input shaft bearing, but I can't see that. It only makes the noise when you are in higher gears ie 4,5, and 6. It is extremely loud when next to a road divider. If you push the clutch in it goes away. At neutral it does not produce sound, when I rev it does not produce sound, if I downshift it makes the same sound. I have had both axles replaced, tires, and a new clutch kit installed. Any ideas?
