How to Wire a 4L60-E

The 4L60-E automatic transmission was manufactured by General Motors and has been used in various GMC, Chevrolet, Cadillac, Buick and Pontiac vehicles since 1992. For the GM 4L60-E transmission to operate properly, it must first be wired to the vehicle's power source. Luckily, this is a fairly simple procedure that only requires that the vehicle be lifted and secured on jack stands. It should not take you more than 15 minutes to wire your GM 4L60-E transmission.

Instructions

1

Open your GM vehicle's hood and unplug the negative battery cable with a socket wrench.

2

Lift the GM vehicle with a jack and secure the front end of the vehicle on jack stands.

3

Crawl underneath the vehicle and remove the air cleaner from the transmission with a socket wrench to remove its bolts.

4

Squeeze the wiring harness on the transmission, located on the end of the transmission closest to the firewall, and pull it out. Perform any maintenance necessary on your 4L60-E transmission. When you are done, plug the wiring harness into the transmission until it clicks into place. This will wire the transmission.

Reattach the air cleaner then raise the vehicle with the jack and remove the jack stands. Lower the vehicle and reattach the negative battery cable. Close the hood.
