The 4L60E is a 4-speed (meaning it has 4 gears) transmission, with gear ratios of 3.06; 1.63; 1:1; 0.70 (overdrive). See all 20 photos The transmission control sub harness plugs in on the passenger side for 4L60E and 4L65E applications while the 4L80E and 4L85E transmissions have the plug on the driver side. The transmission typically has pinned flare & o-ring fittings on the passenger side for a cooling circuit. A transmission control module is an electronic mechanism that collects data and processes signals within your transmission in order to regulate the transmission’s gear shifting. Some more recent transmissions have the controller inside the transmission and god help you trying to fix one. finding it really difficult to get any info on this however from Google or other mechanics i know. There is a portion of the PCM’s strategy for shift stabilization, which helps to reduce hunting.
