I used Mobile 1 75-90 with LS additive. filled it until the fluid was right at the fill hole which is just over a quart. No metal shavings were in the original fluid. Just the gray sludge on the magnets and it was dark. Went out first thing after changing the fluid and the groan was horrible cold around turns and took a longer to go away.

So yesterday I went to Napa because they said that they carried the AC Delco fluid. I went there and it was Auto Track II TC fluid. I was pissed because I even gave them the part number over the phone. So I went ahead and purchased Valvoline 75-90 with LS additive and also grabbed a tube of Trans X LS additive. SO I drained the fluid again, added a half quart of diff fluid, then the tube of Trans X, and topped it off with DF. Went out and did figure 8's in the parking lot and the groan was gone. Honestly it was the smoothest this car has felt around turns in the 900 miles I have drove it.( I bought the car as a CPO 1 owner with 900 miles. The groan started around 1500 miles... It now has 1800 miles. I love the car, just hope it's not going to be plagued with little problems)

Anyway, I Let the car sit for 4-5hours, started it up, first turn the groan was back. However it went away fairly quick.

So I went ahead and ordered a couple quarts of AC Delco fluid with additive and I will try that. If groan persists I am taking it into the dealer under warranty.
