Ford Repair: ABS light, ford explorer eddie bauer, explorer eddie bauer

Question
I just purchased a 4x4 1994 Ford Explorer Eddie Bauer..my ABS light is on all the time..we just replaced the brakes...I also have a vibration around 45 to 55 like it is having a hard time going into overdrive...could that be the torque convertor? We changed the transmission fluid...Would the ABS have anything to do with the vibration? also....my check engine light also comes on but I read in one of the other questions what that might be..I also have a
little knock but only when I back up...I kind of feel like my explorer should have a little more gettyup and go but maybe I am wrong?

Answer
Hello and thanks for the question...I'll try to help.
 I would bring it ta a garage and have them go over it. You have listed several problems, with out a description of them. Have the light checked out. have the ABS light check out, have the U-joints checked out, and have the vibration checked out.
