blew the rear in driveway?
I had my car on blocks to bleed the brakes all wheels off. I finnished the bleeding put the car back on the ground went to test drive it and moved forward about three feet touched the brakes and it felt like the brakes had locked up . I gave it some gas to get it going forward and bang! one loud noise and that was it - no forward no reverse. What happened?

Speaking solely onmy own recent experience with the brakes, mine were locking up on me on the road once the car warmed up right after I rebuilt them (new calipers and all). Turned out my issued was two fold: overfilled master cylinder and the pushrod coming from the booster adjusted all the way out (by the "corvette specialty" shop I had tried initially). I adjusted the pushrod and lowered the fluid to about 1/4" or so below the top and all has been fine since.
Now if the brakes caused the transmission to blow or if the transmission just reached its time, who knows but that sounds like the end result.

You need to do a little research to find exactly what has failed. Try putting it in neutral and try to roll the car. You may have to unhook the drive shaft to see if the rear tires will turn. Pull the wheels to see if the brakes are locked up. Too many variables to guess what has caused it to lock up.

Sounds like you broke a yoke, u-joint, flange etc.
I'm sure if you got it jacked up and looked underneath (inspect the entire driveline). You'll find your problem.
Place the transmission in Neutral. After the back tires are off the ground, have a friend slowly try to turn one of the tires by hand while you look underneath (make sure to use jack stands!!!) And be careful the friend doesn't get too into it and knock the car off the stands
You are looking to make sure the Tire, half shaft, and yoke on BOTH sides are turning. The driveshaft itself should also spin.
Good luck!

If the brakes DID cause a ujoint or trans to break then you're lucky it happend in the driveway! It was obviously a very VERY weak part and ready to fail

was driving a 76 jeep cj down the road one day when the infamous 2 peice axle seperated;
it was very exciting to say the least.
i would say you are lucky that whatever happened was kind enough to happen in the driveway at low to no speed.

This happened a long time ago but sounds simular to your problem.
There used to be a station in town that would let us change oil and grease our cars for a fee. Anyway I did my mantenence and went to back out of the shop and it would go about three feet and stop forward the same thing. There were others waiting to use the rack so I finally took the half shafts out of the car to get it out of the bay. Upon disassembly of the rear I found the bolt that located the cross shaft for the spiders had backed out letting the shaft slide partually out of the carrier. Had this happened while going down the road it would have tore up jack, as it was I pushed the pin back in and reinstalled the locating bolt with some loctite.

If the car can roll Get underneath and look at both 1/2 shafts while rolling the car. If one goes forward and the other backward that shaft is broke. I'm not sure but think it rolled in gear too.
I did this in a parking lot by myself so it isn't very difficult to do. If its broke it rolls easily. Mine made rotational noise while in gear. The spindle broke internal to the hub.
Oh- Mine broke not while accelerating but when I hit the brakes for an idiot. This is like yours... lucky for me it happened where it did.
