P0950 code?

Anybody know possible causes/fixes for a P0950 code?
Says it's the auto manual shift control circuit, probably a transmission wiring issue, but I have a 6spd manual V6, and I thought that code was just for auto trans?
No problems with how it drives or shifts, just confused what the code means.
Thanks!

Found a different issue by searching “p0450 Tacoma”

One of the mechanics might have better insight, though.

 

If you have a manual shift standard transmission that code in not applicable and I have no idea why it would show up.

Are you sure your have a P0950?

 

I'll check it again, the guy at pep boys just handwrote the codes on my receipt. The P0450 would make a lot more sense considering O2 sensor codes are also on, and I bought it with headers, custom pipes, and a Flowmaster muffler.
Thanks
