Description Reviews

Easily manage your GM 4L60E transmission with the MicroSquirt CAN Transmission Controller and 4L60E Subharness. This system offers a clean, plug-and-play solution when paired with MS3Pro ECUs and directly connects to our LSx drop-on harnesses for quick and painless installation.

The included subharness supports 4L60E transmissions with or without the LUF (Lock-Up Feel) solenoid. It is ideal for GM vehicles running early 4L60E models and LS engine swaps using MS3Pro or other MegaSquirt-based ECUs. Communication is handled over CAN bus, allowing compatibility with MS2, MicroSquirt, MS3, and MS3Pro systems.

Note: This harness does not include wiring for the input shaft speed sensor found on later 4L65E and 4L70E transmissions.
Not compatible with 2009+ 4L60E transmissions.
