If I had to guess, I'd think the module/controller has issues, or the shift lever isn't triggering the right mode (manual vs. auto) which could be a contact/switch issue in the shifter mechanism. Since it works sometimes, and since modules using fail 100%, it may be a shift level/contact/switch issue.

Access to a diagnostic tool to read any codes the ECU is recording would go a long way to helping you figure out where the issue is.
