Stupid question. When i drive car around for maybe 30 min, i get a squeal sound. I cant pin point from where but sounds like the trans area. I checked trans fluid and its at proper level. Ok...heres where it gets good. Once its sqealing i turn car off the sqeal slows then stops. I dont know what would still be spinning/sqealing when car is off. When i drive car and get on it alittle bit the trans slowly shifts into 3rd. Any predictions on what it would be?
