When a Dodge vehicle experiences the code P1740, this signifies an internal transmission malfunction. This trouble code is triggered when the Power Train Control Module (PCM) detects an invalid engine speed to output shaft ratio with the Torque Converter Clutch (TCC) or Overdrive Clutch engaged. This code is usually caused by a variety of factors, including ATF fluid that has become burnt, contaminated, or contains excessive debris, A/T cooler flow restriction or problems in the oil pump shaft, internal transmission problems, or damage or failure of the Overdrive clutch or TCC clutch. Additionally, the transmission valve body may be leaking, damaged, or have failed. To help identify the root cause of the P1740 code, it is important to understand the possible causes and how to address them. Below is a table with a list of causes and solutions for the Dodge code P1740.
Causes and Solutions for Dodge Code P1740

ATF Fluid
When an ATF fluid becomes burnt, contaminated, or contains excessive debris, this can cause the Dodge code P1740. It is important to check the ATF fluid for any signs of contamination or excessive debris, and replace it if necessary.
A/T Cooler Flow Restriction
Another possible cause for the Dodge code P1740 is a restriction in the A/T cooler flow or oil pump shaft. To address this issue, it is important to inspect the cooling system for any blockages or restrictions in the oil pump shaft.
Internal Transmission Problem
If the Dodge code P1740 is caused by an internal transmission problem, it is important to inspect and replace any faulty Overdrive clutch seals or valve body. Additionally, if the Overdrive clutch or TCC clutch is damaged or has failed, it is important to replace these components as well.
Transmission Valve Body
The transmission valve body may also be leaking, damaged, or have failed, which can trigger the Dodge code P1740. To identify this issue, it is important to diagnose and replace any faulty transmission valve body.
