Ok guys i ve got a 1986 5.0 that ive had since new and has about 180,000 miles and heres whats going on.The car started to get hard to shift and i pulled the transmission and took it to a trans shop.While they had transmisson i stuck in a new king cobra clutch and had the flywheel resurfaced.After like a week shop called me back saying they stuck in a new main shaft supposidly and some misc little stuff they also stuck a new yoke on my driveshaft and balanced it too.Well i go back to shop and stick it back together and go to drive it and around 3800 to 4500 shifter shakes really bad,but if ur running it thru the gears with it flat on the floor and it passes that spot it smooths right up.If u come to a complete stop and just rev it up u dont feel a thing nice and smooth.I ordered this car since new and its never never ever gave me any problems i stuck a clutch stuck in it like 10 years ago still looked good when i pulled it out just couple months ago.Idles fine plugs are recent has ford motorsport wires its box stock like factory air fitler and pullies and such.i searched for vaccum leaks and notta.Double checked my timing,harmonic dampner looks fine.I pulled the serpentine belt off and took it for a short drive too still has the vibration so i pulled over stuck it back on to.Do u all still think its its in the transmission mmmm or what else am i missing that i should be looking at.Any help would be great too i figured maybe someone else has seen or ran into this before and iam new to site too.Thanks too
