my 80 is officially installed. been fooling with the trans stuff getting it ready to shift right and things. well my speedometer wont work. i mean it gets up to maybe 20 mph. whats goin here!?!!

 

When you did the segment swap did you also change all the transmission related tables and speedo calibration? Congrats on the swap btw.

 

I copied the trans and trans diagnostics. I did not copy the speedo.

 

Copied the speedometer calibration and nojoy. Abs and trans are not jiving

 

After changing out speed sensors in the trans and no result I decided it had to have something to do with the tune. I was reading roughly half of my actual speed. So I divided the vss pulses per mile by 2. That got everything working again. It's still about 4 mph off. But at least I know how to bring it in.
