Shift solenoid?

Default Shift solenoid?

My 2003 Montero Limited is having transmission issues. My daughter was driving it and when accelerating from a stop, it wasn't shifting gears until very late, etc. It also threw a code for the input/output shaft speed sensors. I've replaced both of those sensors. I haven't test driven it, because now it won't shift into reverse. The shifter will select park and nuetral, but when in reverse, it just like it's in neutral. When I select drive, it engages drive, although I haven't driven it yet to see if it shifts correctly, maybe later on I will pull it out of the driveway, so I can drive it forward.

Fluid level is at a reasonable level.

I had my daughter shift it into reverse while I was underneath and I hear a buzzing noise that lasts for several seconds each time you select reverse. (engine is off). It sounds like an electrical buzzing noise. I also can't really tell where the sound is coming from, so I guess it's on the top of the transmission (ugh). Do all Montero Limited make a buzzing noise when selecting reverse? Or should it just be a click of a solenoid activating? (can someone give that a try). The sound is definitely not inside the cabin.

Is it possible to replace the shift solenoid with the transmission in? (maybe tilt the transmission down or something?) I can't find anyting online about this, it must be an unusual problem.

One more detail. The electronic buzzing noise made when shifting from neutral to drive is different than the sound made switching from neutral to reverse. Similar, but different.

Is there a solendoid for each gear shift? 1 - 2, 2 - 3, 3-4, etc?
