When I bought the van it didn't like to reverse. It would have to be slowly backed up. Now when I have to back up, I'll push the gas and it just sends the rpms up and revs the engine and it might back up a little bit. I can not under any circumstances park on a incline to where I have to back up a hill, even the slightest or it will not back up at all, it will actually go forwards and get even more stuck. Lately, even parked on a flat surface I have to go from reverse, put the van in park and then put it in drive or it gets stuck in the reverse momentum and won't move at all. Is this my transmission going bad and I need to replace it or my vehicle all together, or is there something else I can check or do. Everyone I've talked to says transmission. But I don't want to have to replace that if I don't have to. I will if I have to though of course. Or just buy a new vehicle.

It goes forward with no problem. it was acting like the brake was on when in reverse and now it wont do anything in reverse.
