If the power control module (PCM) communications cable was oil-shortened, it could cause damage to the PCM, but it does not necessarily means the PCM should be replaced. That depends on the severity of exposure to the transmission oil. Oil causes corrosion, electrical shorts, and damage to electrical circuitry and can cause the PCM to fail. If the damage is severe or not, due to exposure to transmission oil. It is best to refer to a certified mechanic or technician to assess the extent of the damage on the PCM. The technician will have an accurate diagnosis and do the best course of action if it only needs repair or replacement. I hope this helps!
