Do I need to remove the L and R cats to remove a 4L60E from a stock 2002 Z28? The manual says I have to remove them, but it looks like if I can slide the transmission back enough, I can clear the cats. The reason I do not want to remove the cats is that it is all rusted and I know I will snap the bolts. This is my daily drive so I cannot have a lot of down time. In addition, if I snap the bolts that hold the cat to the exhaust manifold, I will most like need to remove the exhaust manifold to remove the broken bolts, which will create added time and expense. I already have to cut my Y-pipe because it is welded on. This is turning into more of a project than I bargain for. Any recommendation/experience would be appreciated.
