Hello and welcome to JustAnswer!

There are several things that can cause either of the issues you're having and it will take some testing to determine what is going on. If the two problems didn't start at the same time then they are most likely unrelated, but the trans controller does rely on a rear wheel speed message from the ABS module for shifting control.

The first step in diagnosing the problem is to use a scan tool to see what fault codes have set in the ABS module and transmission control module, and then testing can be done from there based on the findings.
