How to remove?

I know. That's what makes it funny, haha.
I've always wound up using an impact gun. I got a 1/2" plug in electric one years ago for a screaming deal that is probably used 90% of the time for flywheel and balancer bolts. Don't know what I'd do without it.

I did a front diff swap today with my dewalt 1/2” cordless impact. Every bolt.

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.
