Its shift points were a little messed up already due to vacuum issues that I didn't have time to get sorted out, it could be related to that as well.

This '83 tranny doesn't have a kickdown cable, it's electronic. It could be bad, certainly, but I (unless it's stuck in kickdown mode) don't see that being the issue.
