Thanks, that’s just my ignorance showing, I’ve heard a lot about bands getting tightened, but only got my first automatic a few years ago so don’t know much about them. This guy has done a couple of T case tebuilfs and a NV4500 for me and has always done great work. Hi ne Toyota 5 speed he did, he asked me how it was and I told him it was still hard to shift so he took it back out and replaced two gears for no labor just parts. And that was 4x4.Good luck with him "tightening the bands".
If he charges you for that, demand to see the old pins. If he won't show them to you, he's either a fraud, or a hack.
