after sitting for over a year,put in new battery,and she fired right up,however no shift or speedo.i changed in and out speed sensors with no affect.read more posts,and started checking grounds.code 66 comes up.added a ground to controler box,but i'm guessing ground is one of the many wires.where do i look next?

 

update:I got a can of contact cleaner and went over the plugs on pcm and sensors on trany.checked ground wires on pcm.still no good.

 

66 No CCD messages from TCM (A/T) Harness and connector Have you checked for voltage on the input/output sensors ?

 

thanks for your help,hains book isn't much help.voltage at plugs is .002 which is like 0

 

should be higher , like 5 volts if I remember correctly, trace the wire back
