Trixie thought he was happy and recalled he was fairly reliable as a pony, so to her when she remade him she thought he was happy.

Very positive ironically, she didn't really meet her in person back in SH, they didn't even manage to lock eyes since she was fighting with Shining till both ended up asleep from love draining from the world. So she gets to properly meet her in DoTL. They bond over loving Sparkle family members.

They are on good terms as that was Trixie's actual first time interacting with her let alone talking to her
