4L80e transmission question

[Steve Chryssos]

Massaging, if any is as simple as heating up the area with a propane torch and tweaking with a hammer. A few love taps is all that is usually required. Stock subframes usually do not require mods. Aftermarket subs usually raise the engine a bit to make steering rack clearance. In that case, the tunnel might need tweaking right where it meets the firewall. We have a big block/4L80E/stock clip car with no tweaking.
