4l80 trans
#2
Remove the bolt on yoke and get a slip yoke for a TH400. A real TH400 slip yoke does not have splines all the way to the open end that goes into the trans, the splines start about 1 1/4" in. There are other yokes that have splines all the way to the end but if you use one of these it will bottom out too soon, won't have enough in and out travel.
The right yoke should go in all the way up to the seal.
