I purchased a rebuilt transmission and when i tried to bolt on the yoke it moved too close the the actual housing and didnt have a gap like the old 4l80e transmission. I'm guessing this rebuilt 4l80e uses a slip yoke. If I use a slip yoke do I have to change the length of my driveshaft? If there is a matching length slip on yoke then what vehicle is it on? I need to so I can find the part.
