This family of electronically controlled automatic 4-speed overdrive transmissions are in many General Motors rear wheel drive vehicles from 1993 up through 2014. They are strong and reliable transmissions that will give good service up to and over 150,000 miles if maintained and treated properly. Many OEM and quality aftermarket parts are available, which makes rebuilding these transmissions a common economical alternative to buying a replacement. I have worked in the performance camshaft manufacturing industry most of my life, but I enjoy working with anything mechanical and that includes automatic transmissions. The 4L60E family of transmissions have become my favorite and I have chosen to specialize in them. These are the only transmissions that I currently work on. I have tried to give detailed information on my transmission services, please read carefully through all of the pages.
The old and dirty transmission in the photo above is my own 1993 4L60E with 265,152 miles before being rebuilt. It was slipping and having problems when I decided to rebuild it. The transmission had been well cared for and the inspection showed no major issues. My standard rebuild service along with some added components got the transmission back in great working condition.

Remanufactured 4L60E vs. Rebuilt or Used. There are over 60 different variations of the 4L60E (so we have over 60 different part numbers!). Each one for a different engine size (bellhousing), 4WD vs. 2WD and varying electronic and solenoid systems for different years. 4L65E models are. With its hard parts spread out on the Performance Automatic build bench, the 4L60E doesn't look.
