The check transmission light may illuminate with a stored code 37. This is commonly caused by electrical interference on the data communication circuit between the transmission control module (TCM) and the engine control module (ECM). Our technicians recommend that all related connection and ground locations should be inspected and repaired as necessary. In some cases electromagnetic interference may be the cause, shielding of the affected wiring may be of help it this case.
