Default No overdrive

hello im a new kia owner and just bought an 03 spectra ls. car runs great but has no overdrive. Took it to mechanic and he found the following codes p0763 and p0604 can anyone tell me what the codes are? Also overdrive swith feels like its not engaging is it supposed to stick in when pressed? Also od off indicater does not illuminate in dash so could it just be the switch before i spend money for repairs i dont need. HELP!

Welcome to the forum. The two codes you have are:
P0763-Shift Solenoid C circuit malfunction
P0604-TCM RAM error

Check out the website listed in my signature line for a full description on both codes, as well as diagnostic steps. P0604 looks like a bad trans control module (internal fault). The P0763 could be wiring, the shift solenoid, of faulty TCM. I'm willing to bet the P0763 is related to the TCM. Usually anytime a control module sets a code for an internal fault, it's toast. I would start here (perhaps a used unit from a salvage yard vehicle or an online source.
