Got my oil changed yesterday. After I pick it up, it had a CEL. Sweet. Bring it home, Code 70: Automatic transaxle. 1997 Integra RS with about 160k on it. I reset the ECU hoping it would just clear, no dice. A few questions. 1) How many different possibilities could this be? 2) Could the shop have done something to cause this? Or is it just bad luck that it came on when not in my possession? 3) What should I do about getting this fixed?
