Compatability
*2007 Avalanche 5.3 short block
*241 heads
*LS6 Intake with 3 bolt throttle body with cable
* 2000 4i60e out of a firebird
* no ecm or harness at this point
My understanding from doing some searchs is that I might have a ecm issues with the 07 working with the transmission.
Do I have any other issues to worry about to make this combination work
Thanks in advance for your advice.
