Hmmmpretty straight forward swap?
Ehhhh kinda. In short you need.
- 6.0 flex plate, spacer, bolts
- ECU segment swap to know how to use the 4l80e. HPtuners, Nelson etc can do this.
- A bit of harness modding to deal with the extra speed sensor
The 4l80e is a bit longer so moves things about. So......
- HD front drive shaft if 4x4, its longer
- Shortened rear drive shaft
- Modded trans cross member
- HD trans fluid dipstick and tube
- Modded coolant lines.
I'm sure I'm forgetting things but its not killer. Plenty of threads out there for this.
$1500 if you play you cards right. You end up with a killer trans though. When I'm done I'll then move on to the 14bolt rear end.
THEN TURBO TIME!!!!
pretty straight forward swap?



can't wait to finish them...should look great once done
