Whats wrong with my speedometer? please help

Hey whats up everybody, i have a 95 Galant and my speedometer one day just started acting crazy like first it just dropped to 0 when im crusin at 30 mph and every once in a while it jumps to like 70 or 80 and sumtimes it tells me the right speed and when im like crusin at 65 70 itll like jump to like 130 140 and then drop back down to 0 and repeats the process and at the same time that happend with the speedometer my cruise controle went out. can anybody enlighten me on what the problem may be i had the speed sensor in my transmission changed and that still didnt work so i dont know what the problem is all the fuses are good to and i dont see how all of a sudden a wire came loose or shorted cus i never messed with them

go to dealer for a check up asap. my friend got a corvette, that car had option of telling the speed in kilometers per hours or mph at one time only, so if urs gotta a switch in between those two, then its messed up, but I do not think you got that so the only thing you need to do is go to dealer and check electrial componant ini that car

It brings character to your car... I don't see any problems.
