no the speed sensor could be miss reading the gears, check/change the tranny output speed sensor, and the rear wheel speed sensor (on top of the differential) and pull the diff cover and check the tone ting around the outside (it looks like a big gear around the outside of the big drive gear, if it was missing teeth in it that could be your problem)

Hydra put a writeup on replacing the rear wheel speed sensor in the DIY,it's got pics of the process.There's other threads in there on rear diff that have pics of the tone ring also.
Also,when I got my D the P/O had the rear sensor replaced.They didn't clean up too good and got scale on the sensor.At first it was reading off,then it just stopped working and logged a P0500. If\when you change the sensors clean up really good before you re-install,they can misread...

Well to fix your gauges you can pop off the indicator and place them correctly for the most part by using the trip procedure you already used.
One thing I IMMEDIATELY noticed is the fact the OP stated he has a:
A 1998 didn't come with those options so I would say that it was upgraded, so with that stated the trans tone ring could have been swapped for all we know. The first thing I would do is calibrate your instrument indicators. After that I would simply get a performance tuner like Superchips or Hypertech and mess around with tire options until you get your speedometer back on.
Also, the stock tire sizes were not just 235-75-15, there where also 31X10.5 15's and 16's, and the 275-60-17 on the R/T. So I would start at these tire sizes. By simply looking under the truck at the spare it will usually tell you what size came with the truck OEM because everyone forgets to change it out. The correct way to find out is to order a build sheet.
Sounds like you have a project truck.
