I encountered an interesting phenomenon. I've had a hard P0741 fault for 3 or 4 years. When I cleared my DTC's the P0741 code would return immediately after 2 consecutive trips. I also had shifting problems. Additionally, I had intermittent hard shifts and the "chuggling" symptom at idle. I also had a vacuum leak from the intake to PCV valve hose line. Long term fuel trims were a consistent +19 to +20. I replaced the PCV hose line. When I started it, the engine stalled with a P0101 DTC. After some investigation, I found a damaged MAP sensor. The sensor stem had broken resulting in the MAP sensor over-reporting engine load and un-metered air entering the throttle body. I replaced the MAP sensor and this corrected the idle problem and the P0101 code. I checked the LTFT and they were back to normal levels. When I did the test drive, the P0741 did not set. I have driven about 100 miles since then, making 6 or seven trips over four or five days and the P0741 has not returned. I do regularly drive over 41 MPH and I've verified the RPMs drop when I'm in 4th and reach 41. Gas mileage is now around 19 MPG in town while it was in the low 16's before the repair. The transmission shifts normally now.
Traded my E500 for a Eldo -00. Runs great and shifts splendid! 60k miles. But....... It has current codes: P0385, P0741 and P1574. They all return after 20-30 miles. Can¨t tell if there was any History codes since they had been cleared. I know that this is a common problem. What should I do to prevent big time failiur?
Hi all. I had a 100 mile trip with my Deville today and about 25 miles into the trip the service engine and service transmission message came on. I was doing about 60 mph and decelerating when it happened. The first thing I thought of was the TCC code. I was right and got the code P0741 Torque convertor excessive slippage.. Now I have never had any shudder, slippage or anything at all til today. Honestly if it was not for the light and message I would not have even noticed anything. It still performed like always, nice and smooth with no shudder. I did notice that engine rpms were about 200-300 higher than normal when the light is on. I reset the light and drove it again tonight. It comes back on if I decelerate from around 50 to 40 without hitting the brake. So basically I am pretty bummed because I love my Deville more than any of my vehicles and dont know what is going to happen with the transmission. I hope I can make it through the winter then maybe I can come up with a decision on what to do. Being the car has 197000 miles and there is rust involved I dont know if I would be willing to try to remove the assembly for repair. I was considering one decision eventually. If it does go bad I will remove it and have it rebuilt and install it in my Seville. (my Seville shudders around TCC lockup and there is a noise in the trans). I am just bummed over this and do not have the time or financial to make any decisions right now. This car has been a wonderful car and owes me nothing so I cant say I didnt expect it. We already lost a trans on one of the other cars and I would hate to lose another. Just thought I would share.
