Question: I need to know if there is a problem with the pcm ram or if these codes are correct

p0604, p0030, p1529, p0763, p0734. These are the codes that have come up on diagnostic scan

P0030 - HO2S heater circuit malfunction
P1529 - TCU request MIL on / Freeze frame to ECU via CAN
P0734 - Incorrect 4th gear ratio
P0763 - Shift solinoid C electrical malfunction.
