Dear Group,

Is there any way I would be able to calibrate the speedometer in my '90
New Yorker? Is there any adjustment, or does a professional have to do it?
It is off by 5 mph (when it reads 50, I'm really going 45) .. not much
but... The thing is, I replaced the speedo with a model out of a '93 Dynasty
and that one is 5 mph off too. Is it the nature of the beast to be off like
that? Could it be the speed sensor? Anyway, any advice would be appreciated.
Thanks in advance..

Were the wheels changed at some point, or was a speed sensor (or
transmission!) replaced with a unit from another vehicle?

I have the original tranny which was rebuilt last November. Had the same
symptom before and after the rebuild. I have 14" wheels that I have never
changed.

Thanks for your feedback..
