My '98 reads speed off the rear axle; I just did a gear swap 4.10 to 3.54 and the speedo is still correct. Check and see if there is a reluctor ring pressed on the carrier behined the ring gear in the rear axle; if there is, your speed sensor signal comes from there-mine did.

yeah i may be rolling with the gps. that p's me off tho.
is there anything i can do to convert mine to read off the rear end? without changing the axle? my only other bet is since the stand alone computer that runs the transmission senses speed. mabuy i can hook up the spedo to the module. i know you can program it to send it out. ill have to call pcs tommorow and see what i can do. the speedometer is electric right?

I've heard of some installing later model year rear ends in their trucks and wiring their sensors in. I've never run into this so I've personally not tried to do it. I don't know if the sensor in rear end would send out the same signal as sensor in trans/transfer case. If your stand alone computer could be programmed to control speedo, then I would definitely try that route first.
