The check engine light is on in my car and the codes that came up were P0128(OEM Brand: Dometic) and P0742 (OEM Brand: General Motors). I would like to know ways I could fix both problems and steps on how to change the TCC myself on my car.

for coe 128 it may be a bad coolant temp sensor as that code says it'snot reading what tstat is or engine temp . for torque converter clutch you need to pull trans to fix it so get a manual or rent one online here for a week. it's way to lengthy to put on here as trans has to be removed.
