Default Engine light on code P1740

Hi guys i have an engine light on, i had it scanned and came up with code P1740 - Manufacture Control Transmission.
I searched on troublecodes.net and it said - A rationality error has been detected in either TCC solenoid or O/D solenoid systems.
Tcc or O/D solenoid performance.
My question is, what do i do now? Do i replace both the solenoids? are they accesable to a DIY mechanic? is it an somewhat easy replacement??
Just looking for advice and some info i dont want to buy hundreds of dollars in solenoids and find out that it wasnt the problem.
thanks for the help.
