Speedometer is off on it's reading in comparison to true speed. The tires are per the door label specs. The problem existed before and after replacing the transmission, with the same reading, no change.
Here is the scenario. Read 30 mph .... GPS and Radar 25 mph
Read 34 mph .... GPS and Radar 30 mph
" 43 mph .... " " 40 mph
" 47 mph .... " " 45 mph
" 50 mph .... " " 51 mph
" 55 mph 55 mph
61 mph 60 mph
67 mph 65 mph
73 mph 70 mph
I cannot figure out why this would be occuring. The gear cannot be the issue, since each tranny had their own and they were not swapped. I have no codes, runs good. I just have to do manual calculations to avoid tickets, you might say.
Any advice on what the problem might be?
