I have a 08 dodge magnum 2.7 liter. There is a leak in my transmission and the car will not move when I put it in drive. I am trying to put some trans fluid in it so I can drive it a buddys shop. Where you put the trans fluid it says to take it a dealer to remove the cap. Can I remove it by myself? I tried to twist it off but it won't budge and I am afraid to force it because I don't wanna break anything. Can I just twist off the cap myself with some muscle or a wrench or something? Please I need help my car is stuck at the parking lot at work!!!
