I know this has probably been posted before, but I have an issue with my digital speedometer on my digital dash.(88 Z31 Turbo, Auto) It only works once in a while and seems to be tied into my overdrive button on the A/T shifter
It seems I can only toggle between third and forth(OD) gear when my digital speedometer is working.
The speedometer cable was replaced about 2 years ago.
Any input will be appreciated. Some insigth would be nice before taking it in. (if I have to)
