Myth Buster Friday Answer

FALSE — and waiting for symptoms is exactly how a manageable fluid service turns into a major rebuild.
Transmission fluid degrades with heat, mileage, and time — losing its viscosity, its friction modifier additives, and its ability to protect internal components long before any symptom appears. By the time slipping, harsh shifting, or delayed engagement shows up, the internal wear that degraded fluid causes has already been underway for some time. Regular transmission service — fluid change and filter replacement at manufacturer-recommended intervals — keeps the fluid in condition to protect the clutch packs, valve body, and bearings that make the transmission function. It also gives a technician the opportunity to catch early warning signs — unusual fluid color, particles in the pan, minor pressure irregularities — before they become failures. The transmission service interval varies by vehicle and driving conditions, but the principle is universal: service it on schedule, not when it shows symptoms. Hope everyone has a safe and enjoyable Memorial Day weekend — we are back on Monday.

Trivia Wednesday Answer

OBD-II stands for On-Board Diagnostics, second generation — and it is the standardized electronic monitoring system that has been required on all vehicles sold in the United States since 1996.

The system continuously monitors dozens of engine, emissions, and drivetrain parameters through a network of sensors. When any reading falls outside acceptable limits, the system stores a diagnostic trouble code — a DTC — and may illuminate the check engine light. These codes are accessible through any OBD-II scan tool connected to the diagnostic port, typically located under the dashboard near the steering column. The reason OBD-II is central to the Bexar County emissions test is that the test is primarily a readiness check of the OBD-II system rather than a tailpipe emissions measurement. The test equipment connects to the OBD-II port and checks whether all the vehicle's emissions monitors have completed their self-tests and whether any fault codes are stored. A vehicle with a check engine light on, stored fault codes, or incomplete readiness monitors will fail — regardless of how the vehicle physically drives. This is why addressing check engine lights and known engine management issues before November 1 is so important for Bexar County drivers.

Oil changes are not glamorous — but in San Antonio summer heat, they are one of the most important services on the calendar. Oil that has broken down from heat, age, or extended intervals does not protect engine components the way fresh oil does. Engine heat in a San Antonio May is already significant, and it only climbs from here. Sergeant Clutch handles oil changes and routine maintenance at the Walzem Road location alongside the transmission and engine repair work the shop is known for. One stop, complete car care. Call (210) 239-1600 or visit sanantoniotransmissionrepair-sergeantclutch.com.
