So, Nick, any word from the dealer? What would it cost for the solenoid change? I am back to the dealer a second time. First time, they reprogrammed the TCM as the TSB states. It threw codes again this weekend, 4 days after the dealer. Another appointment to verify codes and order parts.Just to update, I did a drain and fill today just for kicks before giving up and going to either Gillece or the Dealer.
3.5L on the dot, came out a greyish blue. More grey than blue.
I got 6 quarts of the FZ, so I filled it back up and went on my way. If it seems to get better, ill probably do another drain and fill to try and get more old fluid out in ~1000 miles or so.
