Re: 68 Powerglide doesn’t shift into 2nd after rebuild
I've found that most places that do bench builds of transmissions will cover the transmission if they do a bench build for you, but not the labor to install/remove since they didn't do any of that work. So it's on you in those cases to get them the transmission if there is an issue.
Heck, many of the shops that do full installs don't cover anything but their own work. So if it fails somewhere and you have to have it towed, that's on you too (in most cases.). Once in a while you might find an exceptional shop that does you right, and those are worth their weight in gold. Most shops though, not so much.
