Wont reverse? All of the gears were working fine but one day as I was reversing, I didn't come to a complete stop before shifting into drive which then made a sound like something snapped. After that, it wouldn't go into reverse. it will shift into drive and move forward making a whining noise tho. What could be the problem?

Yes. You broke a circular tightening panel within the gear box, the part itself is cheap but getting to it is a lot of work so its quite costly. Nothing you can fix urself unfortunately.

Kindly state your MAKE and MODEL when asking for help with regards to your product or item.

SOURCE: Transmission problem with reverse

the reverse clutch has failed in the transmission, this will require the trans be torn down for repair.

You could have a shop check pump pressure - usually the cause is a weak pump or problems with the valve body.
Chances are if you just sit in drive at idle, it will also move on its own in a couple of minutes once the fluid warms up.
I never recommend changing fluid after 100k.

I would be checking the oil level in the gear box as if it is low there may be a oil pressure problem that is not locking up the band and clutch to make reverse work. have a pressure test done on the gearbox to check for internal problems. IT is possible that the oil pick up was out of the oil and the box pump was not working

A standard tranny can get stuck in gear while in reverse position, like somebody slammed it into second and the linkage hit reverse instead. Could be minor, then again, It could be major. I hope it is a standard you are talking about, If it is automatic, then no, there is no switch or fuse for this, it has shift solenoids in the valve body that do the shifting, mostly electric now days, a ground wire off could cause this but I doubt it. I would get a hold of the seller and give him back his car. Hope this helps, Tranny work is $1200 minimum.

Have your transmission oil filter changed;
it is located under the transmission pan
The oil is what makes the transmission shift
When you shut off the engine it stops the transmission pump then when you start up again the transmission shifts until the filter clogs again
