These transmissions are perhaps the most widely used in custom applications due to their versatility. They are easily tuned, but if you need some help getting your calibration set up properly I can help. I can also help if you are having trouble installing or troubleshooting your system.
Once I am done with research and development with the 68RFE, I would like to build a 6 speed 4L80E with the PCS 6 speed valve body and offer full support for that upgrade.
If you need tuning support for a 4L60 or 4L80, sending me a datalog is the first step. Learn how to do a datalog and calibrate your throttle position sensor by watching these videos.
