Ford Mondeo 2.5V6 1998 P0741 Transmission Fault: Is It the Torque Converter or Range Sensor?
Hi everyone, I'm experiencing a recurring issue with my 1998 Ford Mondeo 2.5L V6 24V automatic transmission, diagnosed with fault code P0741. The car is a UK-spec model, but I believe the underlying issues are similar to those in American counterparts. The problem started while driving at around 70mph when the 'O/D Off' light began flashing unexpectedly. At first, I didn't notice any change in vehicle behavior—no loss of power or unusual vibrations. However, once I entered town roads, I noticed a jerky shift from Park to 1st gear, followed by a clunky transition into 2nd gear. The car would not engage 4th gear at all, and I was told this indicated the transmission was in failsafe mode. After bringing the vehicle home, I took it to an automatic transmission specialist. The next day, while driving to the garage, the O/D Off light turned off, and all gear shifts returned to normal. A diagnostic scan confirmed P0741. The first mechanic recommended replacing the torque converter. However, a second specialist performed manual tests—applying full brakes and pressing the accelerator—to check for gear slipping—and concluded that it was not the torque converter. He stated this method has never failed him in years of working on automatic transmissions. I'm now seeking clarity: what could be causing P0741? The light hasn't come back on, and I've been driving only in town so far. The car performs well under normal conditions, but I need to rely on it for longer journeys—up to 200 miles—during upcoming holidays. I'm looking for reliable, factual explanations and troubleshooting steps that don’t require expensive gearbox removal or extensive labor costs. Information on Ford Mondeo automatic transmission issues is limited in the UK, especially when compared to US sources. Any insights into possible root causes would be greatly appreciated.
Just a quick note: The specialist mentioned 'P0741' specifically—though I'm not certain if this is the same as P1741. Could there be confusion between these two codes? Clarifying which one applies would help narrow down diagnostics.
