Installation Steps: Transmission Harness
1.
Start by removing the system from the box and carefully laying it across a
workbench or table. Take notice of the loomed transmission harness which
contains the round transmission connector and vehicle speed sensor
connector. These are the only two connections needed for both 4L60E (65E)
or a 4L80E (85E) transmissions. This system does NOT require the use of the
input shaft speed sensors on the 4L65E or the 4L80E/85E transmissions. See
Figure 1, page 7, for the pin out of required connections.
2.
Next, plug in the transmission connector and the vehicle speed sensor
connector into their appropriate locations on the transmission. The
transmission connector is located on the passenger side of the 4L60E
transmission housing and on the driver side of the 4L80E transmission
housing. The vehicle speed sensor is located in the tail shaft housing on the
passenger side. See Install Pictures 1 & 2 below and on the next page.
