Re: Speedometer out of whack with new 3.73\'s
can't remember what year your truck is but im quite sure you have electronic speedo, no cable, no gears. you eather have to get your "speed sensor buffer" (is what they called it) caliborated or replaced. rancho i believe sells those, there are couple more places but i can't remember. (by the way, its the bar of soap sized flat white plastic box behind the glove box a little to the left and down, one or two plugs) want mine, i fried mine, it reads 0 all the time [img]images/graemlins/smile.gif[/img] i could cheat, if you just pull it out your tranny wont shift. my new one reads 10% or so over, which adds a crap load of miles (forgot about gearing when i got it from a bone yard) but at least i get the oil changes done on time.
