Ok so over the past few years my car has always chugged when going up a steep incline on the Highway..If I hit the gas it stops... If i am at a stop sign and I hit the gas from a stop it shutters like it is wheel hopping... Now after about 30 minutes of driving my car likes to shift really hard..dropping 1000-1500 RMPs between shifts. It will also shift to soon and dog like i shifted from 2nd to 3rd before i gained any rpms. If i shut my car off it seems to reset after a few minutes and is fine for a little while... What the hell is going on???
