NO OVERDRIVE

1985 GMC S15

Transmission problem
1985 GMC S15 6 cyl Two Wheel Drive Automatic 98xxx miles

I can not take off when in over drive. Drive works great. But when up to 45 you can shift into over drive and it will catch and go no problem down highway. Thank maybe tcc switch. If so where is it?
