Default Run your 4L80E swap on a 4L60e tune with no segment swap

If you want to know how to do it you can buy the instructions from this guy

PerformanceTrucks.net Forums - View Profile: slow67

A lot of you guys complain about the lockup on the 4L80e that is built into the 4L80e tune. With this small modification you can run your 4L80e transmission on your 4L60e tune without doing a segment swap. You also do NOT need the extra iss wiring pigtail for the front of the transmission.

Yes here is the original thread. Credit goes to slow67 for the writeup.

PWM slows the converter lockup so it feels softer but it causes more wear on the clutches. If you google it there a lots of people that want to delete it but I dont think its as easy to delete on a 4L60e.


Quick Reply: Run your 4L80E swap on a 4L60e tune with no segment swap
