    hey robert. i saw a thread that you have posted on to try to figure out a grind/roar in first gear..

    I am having the same problem and was wondering if you know what it is. im gonna try to narrow it down.
    the noise sounds like its coming from the front. trannsmision fluid looks/smells good. its still red. i am not sure when tranny fluid was changed. I can hear the noise slightly backing up as well. and yes i hear it if i make a turn when the truck is in 1st gear.. if i put the shifter in 2nd gear, and truck starts from a stop in second gear it does not make the noise.. if truck starts in first gear it makes the noise untill it shifts into second the goes away. and the truck is a 4wd. and makes the noise in 2 an 4 drive. thanks in advance
