The 4L60-E is rated to handle up to 360 ft·lbf (488 N·m) of torque. It weighs 133 pounds without transmission fluid.
4L65-E
An updated 4L60-E, the 4L65-E (RPO M32), was phased in the 2001 model year when coupled behind the 6.0 Vortec. Five-pinion front and rear planetaries, along with an additional 3/4 clutch allowing 7 clutches in the input housing and induction hardened input shaft assembly, were improved to withstand up to 380 ft·lbs (515 N·m) of torque.
