Hi,

Looking for any advice on best direction to go with ECM's, BCM's, trans controllers, wiring changes etc to get a 4L80 to work in place of a 6L80 in a pontac G8.

Old setup:
early 2009 pontiac G8 Gt; 6L80; E38 ECM; 6.0 liter;

new setup: 434 LSX, F1 procharger, RPM 4L80E, ---

not sure on best way to make work considering the ECM, BCM, trans, and wiring changes for shifter, etc... can I use E38 in car now?... original thought was to make ECM think it is a manual and leave TEHCM plugged in (wired to trunk); and use new trans controller for 4L80... doesnt seem to like it and doesnt link all up... and not sure on wiring...
any basic thoughts to detailed thoughts would be awesome!!! everything is in car and ready to go.. now issues...

thanks for any input....
