I have a 85 silverado. Orginally a 305/700r4. I took the 305 and replaced it with a 350 out of a chevelle. The question i have when i put the motor and trans back in my truck it will not go into 3rd gear. I think 3rd gear is burned up. The question i have is what size transmission will fit in place of my 700. I know some of these truck came with a 350 transmission. What size transmission is it and will a th400 work also. I do not want to make any mods to my driveshaft or crossmember. Can any body out there help me.
