SOURCE: why a cadillac won,t go into reverse

Either the linkage needs adjustment, or the reverse gear is gone.

To tell if it is the linkage, look at the letters and see if the shift arrow matches up P,R,N,D,2,1

If the arrow is off and doesn't point at right letter, you should adjust the cable that goes from shifter to tranny. Follow the cable and there will be an aduster on it. Turn to right to tighten and left to loosen.

SOURCE: 2001 cadillac catera ebtcm removal how to

You need to remove the upper rad hose and the battery.
Then, use a torx to remove the 6 screws (hard to get at) which will remove the EBTCM from the brake modulator. You also must disconnect the two electrical connectors (the big one has a slide tab).
There are places you can send the module to and rebuild with warranty. I took a module from a 99' and installed it in my wife's 01'. Now the speedo, odometer, cruise and power steering work perfect and no TCM / ABS light.
