Updating the 4l60e
4L60 uses a 6.5" depth bell and 4L65/70 uses a 7" depth bell .
They also have different input shafts and torque converters. 4L65/4L70 uses a 300mm input shaft and converter designed for LS applications only.
And sure, installing a heads-and-cam package in an LT1 or LS1 F-body is like sentencing your 4L60E to death row.
Worse yet, in heavier machines like Impalas and GTOs, simple bolt-ons are enough to burn this notorious slushbox up.
Designed for longitudinal engine configurations, the series includes 4 forward gears and 1 reverse gear.
It is an evolution of the Turbo-Hydramatic 700R4, originally produced in 1982.
5 pin planetaries vary by application only Only corvettes and HD vehicles came equipped with 5 pins.
These changes have affected nearly every part used in the THM 4L60-E.Currently this unit is found in all 2001 Cadillac Escalade and any vehicle with 6.0L engine or larger, that was previously equipped with the THM 4L60-E transmision.
