ok so i turn my car off the speedometer needle goes berserk and finally drops to zero...i turn my car back on and the needle is at 20...i drove for a few blocks and the speedometer started working but when i turn the car off and then turn it on...it starts doing the same thing...now the speedometer needle sits at 20 and wiggles when i stop...also the odometer and trip meter are not working either...
what can be the problem..?wiring issue or something...
tranny problem..?i have 105000 miles on my car...
please help...

 

same exact problem did you ever find a solution

 

could be a speed sensor,giving a false reading or shorting out somewhere. i'd check that first,
