Sorry about another speedo issue, but here it is. Before I spend money on something I don't need I want to make sure this is correct.

I need the gear that goes between the tranny and VSS? And, I would be better off getting it from a speedo shop?

My problem is the odo/speedo run equally fast. Reads 70 mph when actually doing 60. Odo reads 10 miles for every nine.

What is the difference between the Transducer/VSS/Distance sensor/Speedo drive adapter.

There is no telling what the previous owners have done to this truck so the only thing I can assume is that;
1. It has 3.55 gears
2. Automatic (93 model)
3. 235/85/16 tires

I cannot get a good mpg until I fix this issue then I can tackle, what I believe to be horrible fuel mileage.

Thanks for your help
