Getting ready to drop the pan on my 4L60E tranny and the shift linkage needs to be moved out of the way.

Need some assistance w/the torx bolts holding the shift linkage. Sprayed real good with PB Blaster penetrant on the torx bolts and let it sit for an hour. Cannot break them loose. I'm worried if I turn it any harder I am afraid i'll strip them. Actually the back bolt feels like it was stripped slightly (by prior owner).

So need some advice on how to break them loose and how to handle the stripped torx bolt. TIA!
