Ford Mondeo 2.5V6 1998 P0741 Transmission Fault: Is It the Torque Converter or Range Sensor?

Model: Ford Fault Code: P0741 Posted: 2007-05-30 06:08

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.

The range sensor could be a likely culprit. It's responsible for informing the transmission control module (TCM) about the current gear position based on shifter input. A faulty sensor may cause incorrect gear signals, leading to P0741.

Thanks for the reply—what exactly is the range sensor? I've heard of it before but can't find clear documentation on its function or how it works. Is there a way to test it without removing the transmission?

You'll need a repair manual—the range sensor sends data to the ECU about which gear is selected, so if it's faulty, the system may misinterpret gear position and trigger P0741.

Could a malfunctioning range sensor still produce a P0741 fault even if other diagnostic codes are not directly linked to it? I suspect this might be an overlooked possibility in some diagnostics.

I'm suggesting that you check the range sensor first—it's a common failure point in Ford Mondeo automatics. A reliable repair manual would provide step-by-step guidance on how to test and replace it, avoiding unnecessary gearbox disassembly.

I'm open to trying any solution. Unfortunately, different auto specialists are giving conflicting diagnoses: one says torque converter failure, another rules it out with manual tests, and a third suspects gear train or electrical issues. None of them offer definitive answers without charging hundreds of pounds for labor—especially if they need to remove the transmission. In the UK, automatic transmissions aren't as common as in the US, and technical resources are sparse. Most repair manuals only cover basic maintenance like oil checks and stop short of detailed troubleshooting steps. I'm trying to rule out simple, affordable fixes before committing to a full transmission overhaul costing at least £600 ($1200). Any advice on how to diagnose this issue independently would be very helpful.
