Why does everyone skip the torque specs on aluminum pans?

I pulled a transmission last week from a 2015 F-150 and found three bellhousing bolts barely finger tight from a shop that 'specialized' in these trucks. Aluminum threads don't forgive that kind of shortcut, and one wrong ugga dugga turns a 30 minute job into a $400 helicoil repair. Are you guys actually following the book, or is this just me being old school about it?

Three bellhousing bolts barely snug on a 2015 F-150 is wild to me because those threads are soft, and yeah, one bad hit with a big impact will strip them fast. I hear you on the $400 repair, that part is real, but I don't think the book is always the final word either. Torque wrenches go out of cal, adapters change the reading, and some of these older specs were written for bolts that aren't even sold anymore. A guy who has done fifty of those transmissions might know a half ugga past spec is fine on a clean thread with a little anti seize, and honestly a lot of dealer techs run them down by feel and never have a comeback. That said, finger tight is not feel, that's just lazy, so we probably agree more than we don't. Maybe the real problem isn't skipping the book, it's guys not knowing when they can bend the rules and when they can't.
