Hey guys, been having a problem with the speedometer on this truck ever since I’ve had it which is now been for probably around four or five months and everything the mechanic’s done to try to fix it hasn’t changed anything at all.
When I first started driving it, on average, it’s about 30 miles an hour too slow. It works, but at normal highway speed it shows I’m doing 30 miles an hour when my Garmin says I’m doing 70 but if I accelerate up to like 80 miles an hour, it may show 35 miles an hour on the speedometer and so far what the mechanic has tried, they put a new speedometer in it and calibrated it to the gear ratio and all that stuff but nothing changed; he claims that he replaced both of the speed sensors that’s on the back of the transmission and still, nothing has changed. He put the original speedometer back in after supposedly replacing both speed sensors and still, nothing has changed.
He even tried playing around with the calibration with the little switches on the back of the new speedometer but yet again, nothing really has changed so what would possibly be the problem? I’m thinking maybe it’s got to be in the wiring harness on one or both of those speed sensors that may be doing something but I don’t know? Any ideas? Thanks.
