Used 10L1000 out of a 22’ Chevy 2500HD.
Just over 200k when I pulled it out of my truck.
I bought a “built” transmission with a few upgrades so I don’t need this one.
It worked as it should when I pulled it out.
I’ve also got the transfer case if you want both. $1500
If you want both I’ll sell them for $3750.00
