Got Transmission Problems? Is your limp mode? The problem could be the TCM. A TCM (Transmission Control Module) is the computer that controls an automatic transmission.

What does the TCM do? The TCM monitors information from various sensors and uses that information to determine when and how the transmission should shift gears. Depending on the vehicle, it can control:

* Gear shifting — determines when to shift up or down.
* Shift quality — controls how smoothly the transmission changes gears.
* Line pressure — helps regulate hydraulic pressure inside the transmission.
* Torque converter lockup — controls when the torque converter locks and unlocks.
* Transmission protection — can put the transmission into a protective or “limp” mode when a serious problem is detected.
* Diagnostic trouble codes (DTCs) — stores transmission-related fault codes that technicians can retrieve with a diagnostic scanner.

What happens when a TCM has a problem? A faulty TCM or a problem with its wiring, power supply, sensors, or software can cause symptoms such as:
* Harsh or delayed shifting
* Transmission slipping
* Transmission stuck in one gear
* No upshifts or downshifts
* Check Engine or transmission warning light
* Erratic shifting
* Vehicle going into limp mode

Important: A transmission problem does not automatically mean the TCM is bad. Proper diagnostic testing is important because wiring, sensors, solenoids, valve-body problems, fluid issues, or mechanical transmission damage can produce similar symptoms.

Count on Sergeant Clutch to diagnois your transmission problems.

Check Engine Light On? Got Codes? PO420 or PO430? Might be time to replace your catalytic converter. Count on Sergeant Clutch for your next catalytic converter replacement. Get the emissions repairs your car or truck needs right when you need them without sacrificing quality or service! This is even more imperative when your vehicle requires highly specialized repairs like the catyaltic converter and O2 Oxygen Sensors. When financial budget restrictions prevent you from handling unexpected auto repair needs right away you may be left without transportation, causing further complications in your life.

The Texas Department of Public Safety (DPS) reminds drivers in San Antonio and throughout Bexar County to begin preparing for new vehicle emissions testing requirements under House Bill 3297. Beginning November 1, 2026, vehicles registered in Bexar County will be required to pass an emissions test prior to registration.

DPS encourages drivers to start preparing now by keeping their vehicles properly maintained. Routine service can help prevent unexpected registration delays by ensuring your vehicle’s emissions system is functioning correctly. Regular maintenance also helps ensure headlights, taillights, mirrors, windshield wipers, tires, and other critical safety components are operating properly. Driving without required working safety equipment is against the law and puts everyone at risk.
