Klaus...don't go too far...I need help with the codes.

We are experiencing tranny problems. It started with the bucking 2-3 shift. We did take the car to the dealer the first time we felt the classic thud. After a software update and a pat on the back, we continued to have the problem. Again, we went back, but there was no lasting resolution. Then, when shifting from 2 to 3, the engine would race, then drop into 3rd. Now, many miles later, no 3rd gear at all.

I just pulled 2 codes: P0740 and P0785

Prior to erasing codes, the message area read, "TRANSMISSION SERVICE REQUIRED"

Mileage: 175K
2.4L Non-Turbo

Engine runs well, low-no oil consumption, but at 800 rpm idle a "NO OIL PRESSURE ..." message appears randomly. Over 850 rpm, the message is gone. VERY concerned about this one.

Thanks in advance.
