Sounds like you need a TV cable adjustment, there is a tech article on how to do it.

My first trans acted like that; no TV adjustment could fix it. I'd just let up on the gas until it shifted into third. The problem was fixed when that trans died and I had it rebuilt... you're right, it sucks for racing!
