ACD is perfectly fine filter.

Thank you for the pictures!

However, the longer you wait (the older your car gets) and the higher the miles are - the cost increases. First threshold is 12k miles, Also, at some point 7 years stops being available, etc..

GM raises pricing in the spring - so about right now..... Todd usually tells you when. Also 4/50 must not expire and still be valid for 3 months

1200 is standard BMW break in fluid changes which I think is very reasonable. I would change Diff, M/T and oil at the same time.

Look at BMW sites, as bolt pattern is old BMW sizes.

Had my car paint corrected and coated. It's black and shiny now. Swapped winter and summer set of wheels and tires.

I would be interested in disabling DRLs. Or defaulting them to off.

Here is ATSV TSB which started the whole underfill thing. Prior to that GM did not care about underfilling the Dex3 filled Tremecs

Given that you are in AZ - thicker fluid might work for you ok. In colder climates, Dexron III (GM adds some additives to their DexIII M/T fluid) is best choice, as it makes Tremec usable in the cold. I am a big fan of BMW MTL 4 - it works great in all climates. But not appropriate for a...

It seems that only GM is concerned with overfill. But Tremec is not. In the other thread I added a link to a TSB for earlier corvettes I believe which started the whole under fill. I think gm was seeing fluid leaks thru the vent under high temps and that was their best of fixing it.

You are right. But trans oil per Tremec should be changed at 500 miles.

New break in period is 1500 miles of driving under 4000 rpm/under 80 MPH - with no prolonged constant speed driving. Diff oil should be changed at 1500 Per Tremec - trans oil should be changed at 500 miles.

I actually thing having both a dipstick and an electric monitor is best. But dipstick is more reliable and avoids a potential oil avenue at the bottom of the oil pan.
