How to remove?

I have a cordless drill, cordless impact, air drill and air impact... I use only my hand tools 99% of the time. I read to much about people saying you can break things spinning the bolts/nuts to fast and I break enough with hand tools. I twisted my other metal tranny fluid line today at the fitting because I'm a dummy.

I mostly use power tools for disassembly. I'll use them during assembly sometimes too, but always finish tightening by hand. I've had too many fasteners come loose later that were installed without that final grunt..
