Okay, Ross-Tech Audi brain trust, here you go – your insight is appreciated.
The transmission went into limp mode – directly into 5th gear upon shifting into drive.
PRND432 dash display is in relief, that is, surrounded by red, instead of being red lettering.
I can watch the measuring block trans. gear go to 1 and then immediately to 5. With brake on, engine RPM is 608, input RPM is 0.
Other contributing factors: The bottom of car was oil and antifreeze soaked after I made the sad mistake of letting a trusted shop replace my timing belt. Many leaks resulted, which I have now cleaned up. Wires were left out of mounting looms as well, that is, left loose. The car is my winter driver on salted secondary Iowa roads.
Prior to this time, the cruise control would drop out intermittently.
Trans filter and fluid changed some years back at 190,000 miles. Yes, I understand it is an old car.
It was suddenly slow to shift.
Vag-Com reads that the trans is in first, then goes directly to 5th. Car drives in 5th. Reverse works.
No leakage visible from trans
Pre-existing ABS brake error as well (Internal Control Module Memory Error) Wiring problem or death knell for module.
Battery was low - this scan is before DTC's were cleared.
Predominant error codes, which clear until the car is moved:
17117 - Gear 3 P0733 - 35-00 - Incorrect Ratio
17114 - Gear Ratio Monitoring P0730 - 35-00 - Incorrect Gear Ratio
18032 - MIL Request Signal Active (Check TCM for errors too!) P1624 - 35-00 –
17087 - Brake Switch (F) P0703 - 35-00 - Electrical Malfunction (My note: This is a pre-set malfunction which is erased if the brake switch is activated).
My pre-existing ABS error: 65535 - Internal Control Module Memory Error 35-10 - - - Intermittent

My plan so far: Check the F125 switch wiring and connector. Thoughts? Condolences? Here is a reference to the F125 switch: http://www.audipages.com/Tech_Articles/auto_transmission/f125switchreplace.html
And, hoping this obituary is premature:
This car, nicknamed Audrey by my wife, has had sooo many hail marys. The transmission that stopped shifting smoothly years ago, but came back after a fluid change and filter (yes, the magnet had 1 CC of metal dust). The cracked block that I watched drip antifreeze from inside the block, under a piston, into the oil pan when coolant was pressurized – the antifreeze boiled off in the summer, but collected in the winter; the oil never reached antifreeze, but the antifreeze dripped into oil! (Water glass fixed that many years ago – it held!) The ABS module replacement. The plugged body drains carrying a gallon of water inside the AC center duct, sloshing mysteriously. The oil cooler plastic pipe replacement. The air conditioning condenser replacement after the shop boogered it. And the problem that it came with originally – a leaky rear transaxle seal fixed without removing the transaxle. All four CV boots. Several brake calipers. Many pads. New tires and polished wheels, all paint removed, buffed to look like chrome, pristine. This light aluminum rocket could pass anything with a tap of the pedal, hug any curve (given the new upper and lower aluminum control arms) and claw through the Iowa snow and ice to get me home. It carried small cousins, sleeping soundly, on long trips. My then-toddler daughter scratched her initials in the door grips. But best of all, this car drove me to purchase Ross-tech Vag-com. My fellow mechanical engineers and controls gurus saw the parallels to the engineering work we do. It’s just a big, fun puzzle.
