What do you mean by "not to full speed"? The vehicle won't physically go as fast as it used to.. or it just doesn't show on the speedometer? The vehicle speed sensor on the older ones is on the output shaft yoke going to the front. They likely haven't changed that with the redesign.

This may be a stupid question but do you have the seatbelts on? I know this has nothing to do with the speed being shown on the speedometer but I know that speed is limited if seatbelts aren't worn.

On mine and from 2014-2017..I believe, when the driver's belt isn't plugged in it shows an icon on the dash but no speed limitation. From 2018 and newer they also have the dash icon but the speed is limited. Also, I believe if the ECU doesn't get a speed signal from the vehicle speed sensor, it may limit engine RPMs as well. That along with the belt not being plugged in can both limit speed. I'm betting you fix the dash speed problem and the other will also go away.

ok seat belt is hooked i did find max rpm is 5000 and steering was stiffer than normal but no speed showing and mileage is not changing

Is it that only the speedometer and odometer isn't working and everything else is? If so after checking all connections between it and the vehicle speed sensor then I would replace the speed sensor but look close at the rotor and pickup. It may have a leaf or something in it. On the old ones it's an open system.
