What kind of transmission does a GM 4L60 have?
The 4L60, along with many transmissions of its generation, was controlled by a hydraulic system. This means that a series of valve pressures made the transmission shift gears. GM made the jump to electronic shifting control with the 4L60E ( E lectronic shifting control).
Can a 4L60E have a bad 3-4 clutch pack?
Your 4L60E has a set of clutches that work with both 3’rd and 4’th gear. It’s referred to as the 3-4 clutch pack. A bad 3-4 clutch pack can certainly cause the 3’rd and 4’th gear to stop working. In fact, once the transmission “shifts” into third, it’ll feel like you lost the whole thing. You can shift into second to get yourself home.

What does electronic shifting control on GM 4L60E mean?
This means that a series of valve pressures made the transmission shift gears. GM made the jump to electronic shifting control with the 4L60E ( E lectronic shifting control). Keep on scrolling down to read more about electronic shifting and its many advantages.
What’s the gear ratio on a GM 4L60E?
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 ). Reverse has a gear ratio of 2.29. It weighs 146 lbs before transmission fluid is added and 162 lbs with it. GM claims that the factory transmission fluid should last the entire working life of the product.
