I own a ford windstar and my transmission seems to get stuck in low gear after it gets hot, normally I can drive around for quite some time without a problem. Last week I was stuck in traffic for an hour and when I started to drive again it would not shift out of low gear, and the rpms jumped a lot higher than normal, I'm not very mechanically inclined and I would like to know if there is any help or does anybody know what the problem is.thanks.
