CAN Transmission Controller with 4L80E Subharness MicroSquirt DIYAutoTune

MicroSquirt CAN Transmission Controller with 4L80E Subharness. 4L80E Plug and Play Transmission Control via MicroSquirt. Seamlessly control your 4L80E transmission with MicroSquirt Transmission Control! The supplied 4L80E subharness provides a simple, plug and play integration with MS3Pro and directly mates with our LSx drop on harnesses; a perfect fit for GM 4L80E transmission.

Includes wiring for the input shaft speed sensor. This can be used as a standalone transmission control solution with minimal wiring involved, but was designed to be a full plug and play, zero wiring solution with our 24x and 58x harnesses.

Note that many 1993 and earlier 4L80E transmissions had a different connector - this unit uses the later style that was used in most 1994 and later transmissions.
