GM Automatic Transmission

GM 700R4 Automatic Transmissions

In the beginning, the GM 700R4 transmission had some major flaws in the durability category. 2 years after the 700R4 was introduced, it was upgraded with a 30 spline input shaft, new torque converter design, along with many internal parts. Since 1987, the GM 700R4 transmissions have proven to be strong enough for a Camaros and reliable enough for the workhorse pickup.

The 700r4 is a 4 speed automatic that is a staple automatic transmission in the GM automotive lineup. Classic car buffs, hot rodders and everday drivers use 700r4 transmissions to get the horsepower to the ground. The 700R4 does not require a computer to control it. The 700R4 will require a 12 volt feed to control the torque converter clutch solenoid. Shifting of gears is done hydraulically.

About 1993, the 700R4 was renamed the 4L60 when the electronic version 4L60E was introduced.
