The automobile fault code U1426 indicates a problem with the Transmission Control Module (TCM) or its related components. The most common symptom is the illumination of the Engine Light or Service Engine Soon Warning Light. The cause of this fault code could be a faulty TCM, an open or shorted TCM harness, poor electrical connection in the TCM circuit, or a faulty Powertrain Control Module (PCM).
The importance of repairing this issue lies in the fact that it can affect the performance of the transmission and lead to further damage. The repair difficulty is moderate, and the estimated repair time is around 1.0 hour. To fix this issue, one should visually inspect the wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins.

Decoding U1426: Understanding Your Vehicle’s Steering Angle Sensor Fault
The u1426 fault code is related to the transmission control module (TCM) in a vehicle. This code is set when the TCM receives an implausible torque converter clutch (TCC) slip request from the powertrain control module (PCM). The TCC is an electronically-modulated converter clutch (EMCC) that helps to regulate the torque converter’s lock-up.
When the TCM receives an implausible TCC slip request signal, it triggers the u1426 fault code.
This fault code can cause issues with the vehicle’s transmission and should be addressed promptly by a qualified mechanic.
FAQ
If you’re experiencing the u1426 fault code, your engine light may be on.
