[Schnabel]

I would open the encoder cases up and check to see what is going on inside of them. When you take the back case off, there is a metal disc inside. Take this disc off, if it comes off with a little struggle, then that part is good. If it loosley comes off, the it was not fitted to the shaft properly. To do this, gently use a pair of pliers to squeeze the four parts that go over the shaft (on the side of the disc facing the transmission) until each gap is closed. Make sure not to close them in too tight. Another thing to check is the side of the disc that faces the transmission (with the near microscopic lines on it) and make sure that there is no debree(sp) or scratches on it. If so then the disc is bad. Make sure to not touch this side at any time. Also make sure the red sensor on the green board is clean. Again do not touch this part. When you put the disc back on, do not push it all of the way down. It is best to use a tool designed to put the disc on, but if you do not have one, leave a little more than a milimeter between the disc and the top of the sensor. Let me know if this helps any!
