Got another problem with my 01 dmax. First i bought it with bad injectors but those were fixed by the dealership free to me ($4100 according to them), then two weeks ago the water pump went out ($610) witch looked more difficult to do then the normal gasser pickup. Now finally invesigated a slight knock that i couldnt tell if it was normal diesel sound or not. Just crawled under and were the tranny hooks up to the motor it has a knock, like its dieseling. It threw me off because it sounds like its coming from motor by the fire wall from inside unless you stick your head by the floor you can hear it. Whats your guys input? I know pretty close to nothing about tranny's and my warranty expires this saturday!!!! lol i just want to have a argument if they say its " normal " just to get me out past my warranty. They already lost there ass on this truck because of the injectors im sure. 121,000 miles im goin to ask about the 3rd gear shift flare while im there.. truck also has a wierd idle, almost like the a/c compressor is kicking on even if everything is off. Heard that could be flex plate related also.. you guys would make a killing off me if you charged for your answers LOL
