Toyota corolla 2007 engine light came on. on 2007 Toyota Corolla

My toyota corolla 2007 engine light came on at 120,000 miles. I used the code scanner to check and received an error code ( P0741 ). Do not know what is going on. Any suggestion or ideas? How much it cost to fix this problem? Thanks for you help.

Perhaps try servicing the transmission
Take it to the shop or dealer to serve the transmission? Is it pricey to fix that?
