Why the 2002 montero sports doesn't want to reverse
For automatic transmission, First check your linkage/cable that moves the gear arm to shift gears, its located on the top of the transmission, most likely this wont be it but it could be, next check all fuses for blown ones, if not lift the front wheels off the ground to a height that will allow you room to get under the vehicle under the transmission, be sure to put a jackstand on each side and the emergency brake on with wheel chucks behind the back wheels.
Once thats all done and the vehicle wont move drain transmission by either a drain plug, if it has one, if not remove all of the Tpan bolts except 2 or 3, the 2 or 3 you want are on the highest end from the ground, now have your drip pan ready at this point, place it at the opposite end from the last bolts, now take the 2 outer bolts out being careful because the fluid will start to come out and it could be hot and/or splatter, on the last bolt you should take it out real slow since it will let Tpan start to drop down letting more and more fluid pour out, once almost all of the fluid is out you may chose to hold Tpan back up[ to then remove last bolt then hand pour the remaining fluid into drip pan and sit it to the side.
Now on your particular make and model locate the reverse solenoid, remove negative battery cable then unplug solenoid and run an ohms test, if t fails replace and put it ll back together in reverse order, pour all the fluid back in and check two or three times while its running and shift the gears here and there.
It should pull in reverse, if not then you should talk to your trusted transmission shop to have it rebuilt.
