SOURCE: My 1995 Cadillac Deville has

The transmission has suffered a big fault - the protection activated so you can't put it in drive and do even more damage. When despite the warning you tried that the defect extended to the engine's ECM which has now gone in protected mode also so the engine has stopped working.
There is nothing you can do, a fault that big can be fixed only at a repair shop - the transmission must be taken out of the car and dismantled to fix it. And i must tell you, it will be very expensive.

SOURCE: 1991 Cadillac Deville won't engage in gear

the idiots must have towed the the car by the wrong end , this will burn out the transmission in short order. Any car needs to be towed with the drive wheels off the ground, if that is not poss then the drive-shaft has to be removed.

If they time out and I don't know that but you would. You may have a relay holding them on and not timing out

SOURCE: vechile will not shift into park or reverse

The first thing to check is the linkage. Sometimes the linkage will slip, Block the wheels on the car (both front and rear) to prevent rolling. Locate the shift linkage on your transmission, and loosen the nut. You should be able to move the shift lever through all the gears, including "P" and "R". Place the transmission shift lever in "Park" (on the transmission) then move the shift lever (inside the car) in the "P" position and tighten the nut (not a bad idea to use a new locking nut here) You should now be able to shift through all gears. If this does not work, you have a more serious problem that may include a worn or broken belt or broken parking pawl inside the transmission.

SOURCE: igntion lock cylinder??

It is usually the lock cylinder that is bad. Is the steering column round? And is it telescopic? It does require some special tools to change the cylinder.
