Was the rear end or transmission in your car ever replaced? If either one was replaced you may have the wrong speedo gear. These speedos are electric and get their signal from the VSS (located where the speedo cable would normally go on the transmission). It goes by "pulses per mile" to get its reading, and the only way to calibrate it is to make sure you've got the correct speedometer gear.

thx, um...not sure. I believe the cluster module has been replaced, but I don't know about the tranny or the diff. I've only had the car a few months, and the guy I bought it from only put a new muffler. I have no idea about the 18+ years before that. Is there an easy way to tell?

nevermind. After taking a closer look at it, I'm pretty sure the transmission has been replace at some point. Probably explains why it has had trouble going into overdrive since he bought it as well.

AWESOME THREAD!  I did the t/c to V8 tach mod (2 51k resistors for all of 30 cents from the local electronics supply store) with directions from the cool cats site (THANKS FOR THE INFO!) and just now did the speedo mileage adjustment using a combo of MasterBlaster's photo directions and joefriday's easier method.  worked GREAT!  Sunday the t/c cluster will be going in place of the digital dash cluster.
