hey so i have an 03 Galant, i bought it like 6 months ago from max madsen (probably a poor choice) but anyways i went to the store the other night and the car was running normal no issues at all, i got home turned it off then about 3 hours later i went out started the car waited for it to warm up before i left, i get in the car and put it in reverse and it wont move, i had to rev it to about 4 thousand rpm before it moved and it jumped back and stopped by itself with in like 5 feet. now remember this is an automatic trans. the car wont move in drive, reverse and even neutral it wont move anymore idk what could be wrong. just some fyi i have only put about 2500 miles on it since i got the car it has more garage time than road time. please leave any suggestions or helpful info thanks
