MOUNTING SENSOR TO TRANSMISSION.
The diagrams on the following pages show the mounting hardware used and mounting
location for the most common transmissions. For most applications, the sensor mounts to the side
of the transmission using a couple of the transmission pan bolts. A metal plate will attach to the
transmission linkage so that it rotates as the transmission is shifted. A rod with a couple of bends
in it connects the sensor arm to the plate on the transmission linkage. This allows the sensor arm
to move as the transmission is shifted through the gears. Each gear will correspond to a different
position for the sensor arm. It does not matter exactly where the sensor arm is when it is in park,
first or any other gear. Once the Decoder has been programmed it will remember the positions.
The Decoder converts these positions into separate a 12 volt or ground output for each gear.
If a Kugel adjustable shifter is being used, you will need a Kugel nut to attach the sensor to
the shift linkage. The Kugel nut is available from Dakota Digital, Inc.
As the transmission is shifted through all of the gears, the sensor arm should not hit either
of its stops, or get ‘bound’ or ‘hung up’. The arm which is mounted on the sender allows for a 1
3/4” throw with the outside hole and 1 5/16” throw with the inside hole. The longer arm which is
sent in the kit allows for throws from 3 1/2” with the outside hole to 2 3/16” with the inside hole.
When properly adjusted, the sensor arm will move through about 1/2 or more of its full travel. If
the sensor arm moves through less than 1/3 of its travel, it may be difficult for the decoder to
distinguish between gears. It does not matter which direction the sensor arm turns going from
Park to Low. Once the Decoder has been programmed it will read all of the gears correctly.
If the typical mounting location for the sensor will not work, the sensor can be mounted
anywhere that will allow the sensor arm to move as the gear shift selector moves. The sensor arm
can attach either at the transmission linkage or at the gear selector knob or anywhere in between.
A universal mounting plate is included to make custom fabrication easier. This plate has
several mounting holes for the sensor, but no holes for mounting the plate to the transmission. To
use this plate, first determine the best mounting location on your transmission and then mark and
drill holes into the universal plate to secure it. In most
instances the entire length of the plate will not be
needed and it can be cut down using a hack saw or
metal shears.
Approximate sender mounting location on transmission.
When moving or repositioning the sensor arm, be sure the slot in the center of the shaft is aligned with the arm as
shown here.
