Never owned a Wrangler before, but love it. Know they are not the quietest vehicle to ride in, but how much noise is reasonable to expect from the manual transmission? Bought '04 from local dealer, with warranty, that has developed noise from trans. Noisy at idle, put your foot on the clutch and noise goes away. Have owned many vehicles with manual trans. and to me it sound classic input shaft bearing. Dealer say no, it's gear noise. How noisy is the TJ trans?
