2000 Dodge Ram 1500 5.9L V8 - P1740 Diagnostic Code Explanation and Transmission Impact

Model: 2000 Dodge Ram 1500 Fault Code: P1740 Posted: 2014-03-30 14:28

What does fault code P1740 mean for a 2000 Dodge Ram 1500 with a 5.9L V8 engine? I recently detected this code on my vehicle, which is a stock petrol/gas model (not LPG). The code appeared after holding the trip light for 10 seconds and cycling the ignition three times. A garage scanner initially showed P1702, but upon rechecking, the actual code displayed is P1740. I'm concerned about whether it's safe to continue driving until further diagnosis. Can anyone confirm what this code indicates and if there are known transmission-related issues associated with it?

This is a petrol-powered Dodge Ram, not diesel. The vehicle is stock with no other reported issues. To provide an accurate diagnosis, I’ll need to confirm the exact code and whether there are any additional symptoms like transmission shifting problems or remote start usage.

My 2000 Dodge Ram 1500 is a petrol/gas model imported from Canada. It has no known mechanical issues, and the vehicle has been driven normally without any transmission or shifting problems.

I don't recognize P1740 in my quick reference guide—currently cross-checking official service manuals. Could you clarify if the vehicle uses LPG (liquid petroleum gas)? Are there any remote start features or transmission shifting issues? Also, please confirm that the code is indeed P1740.

I’ve verified the code again and it’s now confirmed as P1740, not P1704. The code appears in the odometer display when I hold the trip light for 10 seconds and cycle the ignition three times. The vehicle has been gassed with LPG—this is a liquid petroleum gas system. There are no transmission or shifter issues. A garage scanner initially showed P1702, but that may have been a misread. I’m now certain it’s P1740.

P1702 refers to an intermittent malfunction in the Transmission Range Sensor (TRS) circuit—this is not the code we’re currently discussing, but it's worth noting for context.

I’ve confirmed the fault code again—it’s P1740 on my 2000 Dodge Ram 1500 with a 5.9L V8 engine (petrol/gas). Is it safe to continue driving while investigating what this transmission-related code means? Any advice on next steps?

P1740 is indeed a transmission-related code—according to Chrysler documentation, it indicates a performance issue with either the Torque Converter Clutch (TCC) or Overdrive (OD) solenoid. This may affect gear shifting behavior and should be addressed promptly.
