What would make a car not want to go from park into drive?
I own a 2000 subaru legacy with an automatic transmission. I've started having trouble with it not wanting to go from drive to park. Sometimes I have to put my foot on the brake and rev it a bit to get it into drive. A couple times it also hasn't wanted to pull an incline. Could it be that I just need to change the transmission filter/fluid? I'm trying to save my car and I can not put thousands into it. If anyone has any suggestions, please let me know!
