Condition Cause Correction: Customers may also comment on above normal transmission uid temperature. Root cause may be a twisted cooler line on low mileage vehicles. Note: A twisted cooler line may cause DTC P27EC to set in the TCM on ETRS transmissions. (RPO MHS MQC) Inspect for a twisted cooler line, example shown in the picture below. In some cases in may be necessary to remove the under body panels in order to clearly see the cooler lines. If the cooler line is twisted disconnect the cooler line from the transmission auxiliary cooler and untwist it then reconnect the cooler line. If no concerns are found with the rubber being misshaped check the transmission uid level following SI and add uid if needed. If the cooler line is misshaped the cooler line should be replaced then check the transmission uid level following SI and add uid if needed.
