UPDATE


FOUND IT!!! Damn transmission Bolts were the entire problem!!! Put in 2 new bolts (1 was missing, other loose) and good to go.

Only problem now is the P2771 error code....I know its 4x4 Low Circuit. But, what should I be looking for at the tcase? I know exposure to wires and etc... But anything/anywhere else

Unhappy UPDATE! Good and Bad

I have went ahead and found the time to be able to do an overlook on truck. It was the Trans Bolts 1 was loose and the other was gone! But, got it all figured out. Cleared codes and for awhile it was fine. (other than the sound of the truck, it seems as if the exhaust is "under water type sound")

Today, I was heading to work. When I got onto a straight away I thought I'd do a quick WOT. Well, afterwards the CEL popped up. So, I checked the DTC on my Edge CTS2 monitor. its now P0700 and P2771. yet again! Only thing that is super weird is, previously when going on vacation and coming back. I may have every once in awhile checked to see if they're any codes showing. (sometimes yes and sometimes no) But, if they're was. The CEL would never light up. Today, it did. Im now wondering if I need to do an EPC Fooler or TCM tuning. Or even just change out the TCM for a pre programmed TCM w/ trans tuning???

I'm also getting Edge CTS2 monitor having a message now pull up saying.
