In the early 90s there was a problem of development of a heavy-duty automatic gearbox, which could be used in the Hummer cars equipped with the powerful petrol and diesel engines. A principally new four-speed automatic gearbox 700R4 (4L60E) was developed, which got a reinforced hydro block and a special pump’s design that allowed in a high-quality way to ensure engine lubrication. To ensure high-quality transmission’s lubrication solenoids channels were significantly increased. This required the use of updated and enlarged in size solenoids. It should be noted that certain functions of modification of transmission are controlled by electronics. Altogether the automatic gearbox GM 4L60E makes a positive impression. It differs by reliability and reparability. It means that you can repair the automatic gearbox GM 700R4.
