I just bought a 96 Tacoma SR5 V6 4x4 with 262xxx miles. It's automatic. The Gearshift is wiggle or not engage or not firm when I shift it to the R, D, 2, etc. The Gearshift is still wiggle or not engage even I shift it to the D drive. The truck runs good but I just don't like the way it wiggles or not engage like that. Is it the Shift Lock Control ECU or Shift Lock Control Switch or Shift Lock Solenoid? Do you have any idea why? Does anything wrong with it? I need your help please.
