Got an emergency call from my son, he's on the side of the road in Atlanta. 1999 SHO. He says the vehicle will not move. Goes into reverse fine. I told him to try 2, then 1. Just maxes out the rpm's. Then I told him to put it in park, turn off the vehicle, and restart. Went into gear fine, while driving, he said it is making a high reving whinning noise. I will probably rent a Uhaul tow dolly and go get it. Any suggestions on what this may be?????????? Is it most likely the CV Boot or Transmission? Or something else?

Start by checking the fluid level.
High pitched whine with proper fluid level is usually a pump issue. If the fluid is low, that can be the cause of the whine. A broken axle/CV joint will usually make a lot of racket and the car won't move.

When he was home two months ago, I checked all his fluids. As you say with the CV boots when broken you are not going to move. They do give some warning they are about to go, so I wondered if it may be the case. I know with cheaper vehicles they do not last 10 years. I am an IT guy not a mechanic, what pump am I looking at? 1999 automatic with 142,000 miles.

That was two months ago, perhaps a leak has developed since then, or the transmission may have been overheated and some fluid blew out the vent. Checking the fluid level is the first and most logical step when a transmission is acting up.
The CV boots can be torched off the car and the car will still drive, it's when a CV joint breaks that the car will not move. A failing CV joint can make all sorts of noise, but will not result in the symptoms you describe.
The transmission pump is part of the valve body in the transmission and realistically a failure means pulling the transmission to have it rebuilt. It is possible to replace just the valve body and the pump shaft without removing the transmission, but this is usually not something most tranny shops will do since the price of a full tranny rebuild isn't that much higher.
The transmission pump is a very simple design, and "hardening" it wouldn't accomplish anything. The common failure points are the pump shaft, the pump shaft bearing/bushing/seal, and rarely the pump cover. The best bet when rebuilding a tranny is to install a rebuilt valve body with all new pump components. Replacing all the pump components on a valve body rebuild shouldn't add more than $50 or so to the cost.

Just make sure it is the newer style dolly. IE: silver w/ orange writing and L.E.D. lights.

Tow Dolly
Take along two pieces of 2"X10"X3' to extend the stock ramps. In my experience the bottom of the front bumper will drag on the stock ramps. Also do not try to back up the dolly with the car on it, that can be very messy.

Torque converter dumped its guts. ( Now the filter is plugged. ) * That is why if moves for a few minutes after you shut it off. * Change the fluid and filter, and it MAY make it home. You need a rebuild.
