2007 Suzuki Forenza Question: My check engine light has been on fo approx. 2 weeks. It comes on and goes off.

I had two different diagnostic checks done, n two separate days. The codes are P0700 and P0705. Some of the probable causes are: transaxle fault, misadjusted TR switch, open or short circuit conditin, poor electrical connection, failed TR switch, failed or misadjusted TR sensor. What type of repairs and billing am I facing? Thank you.
