Allright I really need some help. My little brother has a 1994 Chevy Cheyenne 5 Spd With a 350 Swap from a 4.3. Well awhile ago his 5th went out and his 5th gear was reverse for a bit and now theres no 5th or reverse at all. He wants to buy a different one for $500 or me and my buddy can rebuild it and just pay for the parts. Any body have an idea of what could exactly be wrong? Shift forks? Syncroz? ALL help needed please and thanks
