This summary uses the existing diagnostic information shown in full below.
The car's brain that controls the transmission is having trouble understanding some important signals, kind of like when a computer gets confused and stops working right.
The Transmission Control Module (TCM) is experiencing a severe error related to the Quad Analog-to-Digital Converter (QADC), which affects its ability to process signals correctly.
The P1723 code indicates a severe error within the Transmission Control Module (TCM), specifically related to the Quad Analog-to-Digital Converter (QADC). This component is crucial for converting analog signals from the transmission sensors into digital data that the TCM can interpret. A severe error suggests that the TCM is unable to process these signals accurately, which can lead to transmission performance issues.
• Transmission slipping
• Harsh or erratic shifting
• Illuminated Check Engine Light
• Faulty Transmission Control Module (TCM)
• Wiring issues or poor connections in the TCM circuit
• Software glitches in the TCM

Transmission Control Module Issue
• Avoid driving the vehicle until the issue is resolved to prevent further damage.
• Consult with a professional mechanic for a thorough diagnosis.
Check with your vehicle manufacturer for warranty coverage on the TCM.
This code has been associated with vehicles experiencing severe transmission issues due to TCM failures.
High – Immediate attention is required to prevent potential transmission damage.
Driving with a malfunctioning transmission can be dangerous and may lead to further vehicle damage.
• Vehicle must be at operating temperature.
• Ensure all electrical connections are secure.
The Transmission Control Module is typically located near the transmission or in the engine compartment.
Q: Can I drive my car with a P1723 code?
A: It's not recommended to drive with this code active, as it can lead to transmission damage.
Q: How do I reset the TCM?
A: Disconnecting the battery for a few minutes may reset the TCM, but this won't fix the underlying issue.
