4l80e Speed Sensor Diagram. The 4l80e was designed to be used in the duty range of the 4l60e and the allison series transmissions these were transmissions. Try hooking it directly to the speed sensor the high ref one.
Direct clutch failure due to case wear at support. There is an early. The controller wants to know the output speed of the transmission and dividing by 27 or whatever is going to mess up shift points to unusable levels.

The 4l80e was designed to be used in the duty range of the 4l60e and the allison series transmissions these were transmissions. See figure 2 on page 9. You will now have two extra wires these will be used for the 4l80es input speed sensor. Try hooking it directly to the speed sensor the high ref one.
