Hey guys, I need some advice. I'd like to pair up a 6.0L LS2 with a 4l60e trans instead of the 6l80e that came with these motors. What is required electrically to make this happen???
As far as I can tell everything should bolt together fine but I'm guessing that I cant just re-loom the engine for the different trans because the LS2 ecu will not talk to the older 4l60e, correct?
I'm also guessing that I cant swap to an older ECU because the tune will be wrong for the motor and the drive by wire will not work???
This must be a swap that is done very regularly (especially people swapping their LS1 for an LS2). What do I need?

 

6.0 ? the lq9, if so im going to be doing the same thing.

 

Over here the GTOs (Holden Monaros) had LS2/4L60E's from 05-06. Its definitely possible. LS2 vettes also used the 4L60E before switching to the 6L60E with the LS3

 

Thanks Pocket. I guess I'll start looking for a monaro loom and computer. Will any 05-06 LS2 harness and PCM work with my DBW pedal? I heard that they can be quite vehicle specific

 

from what little i have read up on other swap threads concerning dbw.there is a dbw learn procedure that has to be done.pop your head over at ls1tech where ive seen many posts about dbw swaps on different pcms.its a common swap but i dont know the specifics about what works better with which parts and the ease of calibrating them together.

 

Cheers, I'll have a look
