I have install 2007 6.2L with 6l80e 2wd in a chevelle 71. Transmission dont work (stay in safety mode i think) because the pcm come from 2007 escalade AWD.
I need tune from GEN4 LS engine with 6l80e 2wd. I think the pcm/tcm need 2wd tune to work properly.
Thank you and scuse me for my bad English!!!
