Just picked up a 92 C1500 that supossedly had a 4.3 swapped to 5.7L. I cant read the engine number without taring a lot off. Transmiision will only shift if Im driving like a race car, 3500 RPM ish and hard into it. Read a lot about the TV cable being the issue. I've done the adjustment a few times and exactly the same. Apparently I should have fried the tranny by now but its still doing the same. Going to order a new cable and see what happens. Do I get one for the v6 or v8 or are they the same actually?
