ok...first problem with my truck, just thot id ask yalls advice. as hard as that is without lookin at the truck..haa. i was shifting from second to third, on a street, and as i was lettin the clutch out and givin her gas, the tach dropped to zero and the light came on. pulled over and stopped. i dont remember hearing the rpms drop. checked all the fluids, were fine. belt was good. started her back up to drive the mile or so home. the tach kept fluctuating from zero to where it was sposed to be, but the rpms didnt fluctuate with it. cant take it to the dealer til monday. think its just a tach sensor gone bad? any other ideas? safe to drive to work tomorrow? thanks in advance.
