The version, which followed shortly thereafter, was known as the Super-Turbine 400. Find out more about your Turbo 400 transmission and how to identify it below. The 4L70E transmission is the same as a 4L65E with a speed sensor located in the pump. This is a durable and very well-known transmission, as it was in production for many years and applied to a wide variety of vehicles, not only General Motors. The Torque-Drive is a Manual shifted Powerglide on the column. It was developed jointly by Buick and Chevrolet to replace the two-speed Super Turbine 300 and aluminum case Powerglide transmissions.

The 4L60 got the E at the end whenever control of the transmission was switched to the engine computer. The L denotes that the transmission is longitudinally positioned. Five-pinion planetaries, along with a strength-improved output shaft, were improved to withstand the 300+ lb·ft 400+ N·m of torque of the 6. It is machined into the transmission in most cases. Later models used a circular style iron adapter which is generally considered the stronger of the two. This version tilted the transmission about 4 degrees in order to better accommodate the transfer case. You can now jump down to the year identification guide.
