LS1 transplant,helping a buddy
Only thing we have is 1st and reverse no upshift.A mistake I made was buying an ebay harness
Had trouble with wires in the wrong place,we double checked all the trans wires to the PCM.
One other possibility is he sent a t56 PCM in for reprograming and maybe the tuner didnt program for automatic.How can I tell by looking at the tune?
Then I guess get it scanned would be next
Thanks in advance to all who posts
