duty solenoid c

[JLHollowX13]

so my awd isnt working, and the tranny is giving me code 24 as a previous code which doesnt make sense to me. the only code im getting when i do current codes is 33 (my speedo doesnt work). does solenoid c control the awd at all, if i replace it will it solve my problem? how much for the part and where is it available? how hard is it to replace as i wouldnt want a shop touching my baby haha. i dont trust anyone but myself with most things. thanks for any help, i just need to get my awd back online.

one more thing, since im getting code 24 as a "previous" problem, could it just be the clutch not working correctly? if so, how much could i be looking at there? is there anything else it could be?
