Rebuilt TH350 transmission stays in third, it has reverse

I had an old transmission in the barn. Been sitting for years. I recently acquired a truck that needed a transmission. So I took transmission to a guy and he put all new clutches and seals and gaskets in it. He did not touch valve body. I put transmission in truck. All I have is third and reverse. No matter where I put shifter it stays in third. If I put it in first it still takes off in third. I can shift to reverse and it works. Only forward gear I have is third. Is that the valve body? Manual valve not lining up right? Thanks
