The following cars use 4L60E transmissions: GM is responsible for some of the biggest automotive brand names in the US, including Cadillac, Chevrolet, Pontiac, and, of course, GMC. Then again, hydraulic systems were also somewhat complicated and difficult to work on at home. It isn’t something most people would be able to fix at home. If something goes wrong inside the ECU, it can take a specialist automotive electrician to get that fixed for you. This is because most of the work is done inside the ECU, the Engine Control Unit. Some might argue that electronically-controlled transmissions can be harder to fix.

Allows for manual control if necessary.There are very few drawbacks when comparing electronically-controlled transmissions to those controlled by hydraulics or mechanically. For a detailed history of how automatic transmissions have been developed over time, ever since the first one was invented in 1904 (or 1923, depending on your view), take a look at this Wikipedia page. Its predecessor, the 4L60 was instead controlled hydraulically. The 4L60E is made unique by being one of the first transmissions to use electronic shift control. The one used in the example here is also a much newer 6-speed, whereas the 4L60E is a 4-speed transmission. Please note that this is not a 4L60E specifically, but it will give you a good general overview of how transmissions work. This is especially the case in the US, where automatic transmissions are extremely popular.įor a quick explanation of how the basic parts of automatic transmissions, if you’re not familiar with it, check out this video. In 2015, about 34% of the cars in the world were equipped with one. On the roads of most countries today, an automatic transmission isn’t a rare sight. “ 4L60E-1” by JSBlaine is licensed under CC BY-NC-ND 2.0. Read more about the 4L60E from Novak Conversions. GM claims that the factory transmission fluid should last the entire working life of the product. It weighs 146 lbs before transmission fluid is added and 162 lbs with it. 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). Keep on scrolling down to read more about electronic shifting and its many advantages. GM made the jump to electronic shifting control with the 4L60E ( Electronic shifting control).

This means that a series of valve pressures made the transmission shift gears. The 4L60, along with many transmissions of its generation, was controlled by a hydraulic system.

6000 lbs gross vehicle weight (GVW) – this means that the transmission can be safely used to haul 6,000 lbs of car along with it.

Longitudinal applications (rear-wheel-drive).

In 1990, GM altered its designations, and so the 700R4 was renamed “4L60”. This previous transmission had been named the TH700R4 (Turbo-Hydromatic 700R4) and had been introduced in 1982. It was first seen commercially from 1993 to 1994, on cars such as the Chevrolet Suburban, Cadillac Fleetwood, and GMC Sonoma. Many updates, of various levels of significance, followed – the most notable of these being the introduction of a bolt-on bell housing (phased in from 1996 to 1998). Produced by GM (General Motors), it was first produced in 1992 and began being phased into the market during the following 2 years. That’s despite the 4L60E transmission problems that we’ll be taking a closer look at later. The 4L60E transmission is one of the most recognizable and well-known on the US car market today.
