I was wondering what i can do to fix my hard shifting on my 700R4. Whenever i put it into drive or reverse, it "kicks" and jerks the truck. When driving, it seems to pause when shifting. It will unshift and pause for like a second in nuetral before going into gear. Any thoughts on what i can do or what is wrong? 85 k5 blazer with an old 305....must have more power!
