my speedo (82 gtv6) stopped working. well, it works occasionally. from what i've read its probably the sender in the trans. but the amplifier behind the glove box clicks when ever the speedo is working. is that normal? also i've aquired a 140mph speedo and would like to switch it with my 85mph speedo. i think i need the speedo amplifier from a later model car. does anyone know if i need a diffrent sender too?
thanks
david

this is the little bastard that seems to flake out and cause all the problems.
assides from the coil pick up (which dont go wrong, unless burned out) I think the hunting speedo needle is caused by bad solder joints on the capacitors and resisitors, hence instead of a nice regular wave output, you get an irratic output that the speedo pcb cant smooth out. I think most of the work is done by this little unit. looking at the speedo, it has a few caps and resisitors in it, but I think they are purely for final smoothing of the signal.
