08 Colorado codes P1876 & P0770 Sign In

I have a 2008 Chevy Colorado with about 104000 miles. For the last couple of months I thought my transmission might be slipping occasionally. Today the engine light came on and I had the codes read. The P1876 lists as possible causes "Open or short circuit condition, poor electrical connection, faulty tap up/down enable switch" and the P0770 lists "Clogged or leaky TCC solenoid, Troque converter failure and open or short circuit condition." I've not tried anything yet because I don't know where to start. I'd be thankful for any information or suggestion.

Those are transmission codes so you need to let a trans specialist look at it.
