Completely covered? Have you checked your oil level? How's the oil pressure on the gauge look?

Check the oil level it's right there in the middle of the hashes. The oil pressure gauge does seem a little bit low always under 40

 

[Garyjw2]

That doesn't look red though, right? Check the dipstick. How's the oil level? You said red oil leaking under it. At least what general area do you see the red oil (probably trans fluid, like Tony said )?

It looks like more on the driver side in between the passenger and Driver seat underneath the car is about the area is leaking cuz when it sits for awhile I can see where the puddle was

Hey I have not been able to check the codes for right when I got back I had to go back to work and don't have a day off until Sunday so won't be able to get it to a shop until Monday. Yeah it's really weird that the old compressor did not let off the air after it was done pumping up but I have been told that I'll probably need to replace those rear shocks.

Also the transmission temperature was up at about 230 would that be enough to do it

The aluminum engines, which yours has, have pumps that move more volume of oil using less pressure than iron blocks. They'll idle between 25-30 once hot and underway they get close to 40 but not over as the relief spring is set for 36 psi. Cold, you'll see 40 or thereabouts until it warms up.

I don't know what you know so bear with me. Behind the motor is the transmission. Behind the transmission is the transfer case. From the transfer case a driveshaft runs forward on the left side of the transmission to the front differential under the engine. The main driveshaft, or propeller shaft as GM calls it, comes out the back of the transfer case and connects to the rear differential.

The part that connects to the propeller shafts from the differentials is called the yoke. The other end of the propeller shaft, the floppy part is the slip yoke. It slips over the splines in the differential or transmission if it were 2WD.

Lots of things can leak here. Fire up the motor if your so inclined and have a camera ready to record any leaks from either idling or a drive.

Nice TT by the way, we're going to get something very similar.

I I am kind of mechanically inclined. Me and my dad rebuild a 1970 Chevelle from the ground up. as long as I have instructions i can do it.lol. that is what I really like about this site everybody here is really fast to help out and I really appreciate the knowledge. I totally understand what you're saying thanks for taking the time I think you might be right with that yolk I think I put an earlier comment the only spot I ever seen a drop when I was under it while it was off was right there at that connection where that drive shaft goes up into the yolk that you're saying more towards the front of the car. Going to get under the car right now tonight have my wife turn it on and try to record some videos I really try to take a look at it. I have been at work ever since I got back in this problem started I finally have two days off I'm going to get this taken care of. I can fix it if I can figure out exactly what it is, i hope.lol. thanks again

Starting to sound like the front differential to me, especially with the TC and Stabilitrack warnings. Hard to tell for sure though.

hey everyone sorry it's taking awhile to write back. I had to take it into the shop cuz it was just beyond what I could do turned out it was broken motor mounts front differential low on a fluid two spark plugs that are bad and one of the spark plug wires. Oil pan gasket needs to be replaced and that's it. Got the motor mounts covered under warranty everything else I need to do. My main concern is just the sparkplugs. Going to try to replace that myself and the oil pan gasket.

 

[Rocket Man]

Good that they covered the motor mounts, those are the hardest to do.

Yea it was a fight I bought a used car from the dealer and it is now 6 months later and told them that I want to see the hundred and 20 point inspection to see if they missed the motor mounts on the original inspection and they could not provide that inspection for me so I told them they need to cover it because the GMC guy said that there's no way I cracked the motor mounts in 6 months

Glad you seem to be getting things figured out. I had some of the motor mounts replaced as well. Must be a bad design from GMC.
