Cannot Reverse or Park

[CB7Nub]

This never happened to me before. I was driving home from school during a regular winter day and when to reverse into the driveway. There was a lot of resistance on the shifter to putting it into reverse and would NOT go into reverse. 1, 2, D3, and D4 worked and shifted fine. I went around the block and tried it again. She went into reverse with some resistance but would NOT go into park. Put the car into neutral and turned off the car. Turned her back on and everything was fine. I can shift into park, reverse, and all other gears fine now. Again it never happened before. This was last week.

1) I'm autotragic. (durr)
2) Transmission fluid was changed 3,000 KM ago with Honda ATF (the new synthetic type).
3) Fluid was full and red.
4) No weird sounds, noises, rumbles, or jolts when shifting from reverse to park or reverse to D4 etc.

Any ideas what it could be?

check the shift cable linkage underneath the car. Your cable either came undone, is coming undone or you cable is stretched or gummed up causing the vague shifting.

Either way, its related to the shift cable, so jack up the car, and check the cable going into the transmission by removing the access cover and make sure its properly connected to the transmission
