****need help with trouble codes****
Hi, I have a 1994 Cadillac DeVille Concours with a V8 4.6L engine. One day when driving on the freeway my service engine soon light came on and when I pulled over I noticed white smoke coming from the side where the transmission and the water pump is located. Ever since that day everytime I drive the car the CEL light comes on and when I began to travel above 40 miles per hour the engine RPM gets really high but the vehicle speed does not increase with the engine RPM. Also, the upper radiator hose swells up. I put a scan tool on my car and got 3 codes. "Code 29 Shift Ratio B problem, Code 52 Defective ECM, and Code 109 Internal ECM problem." Does anyone have any advice on what I need to do to get this problem fixed????
