$$$ diagnostic charges are upto each & every shop.
WE always charge at least 1 hour for diagnostics. RE-adapting a transmission takes approx 45-60 minutes as well.

Make sure that when the SHIFTER is D that their scan tool shows that on live data, as well as every other position.

I would think that there might be a independant in your area that has scan equiptment that can also read those codes as well as live data.

Reading CLUTCH adaptation figures will tell if the trans is still in good shape.
