after having my tranny rebuilt,the speedo stopped working.i replaced the vss and speedo gear.while driving the needle is all the way to the right,and at speed the needle moves counter-clockwise.my car is a 94gt automatic with 3.27 gears and a 21 tooth speedo gear. any help would be appreciated,thanks.
 
you must have one of those canadian transmissions you will need a canadian speedometer to correct this problem....not really...lol.see below.


Sounds like the speedo drive gear is in the wrong way. Have the shop correct it at no charge.
these pics. are from a t5 but i think an aod is similar...
