All forward gears slip big time...can't move itself down the road. Good reverse. When in forward the check engine light intermittently comes on. Rebuild time?? (translation - sell the truck time)

Sounds to me like a line pressure solenoid or major leak in the same circuit. Don't condemn it too quickly. Any tranny shop will have a way to check line pressure and may loan you the tools to check it at home.
