Symptoms of a
Failing Powertrain
Engine and transmission problems don't fix themselves—they only get more expensive. If you notice any of these signs in Pierce County, give us a call right away.
While a solid check engine light means "get it checked soon," a flashing check engine light is an emergency. It indicates a massive engine misfire that will rapidly destroy your catalytic converter.
If your RPMs shoot up but your car hesitates to accelerate, or if your car abruptly "clunks" into gear, your transmission is struggling. This often points to degraded transmission fluid or worn internal clutches.
Vehicles shouldn't leak. If you see dark brown/black fluid under your car, you have an oil leak. If you spot a reddish fluid, your transmission is leaking. Running low on either will ruin the machinery.

Engine & Transmission FAQ
Common powertrain questions from our local Pierce County customers.
For most modern automatic transmissions, a fluid flush is recommended between 30,000 and 60,000 miles. If you do a lot of heavy towing or frequent stop-and-go driving, you should change it closer to the 30k mark. Unlike engine oil, transmission fluid doesn't burn off; it breaks down and loses its ability to lubricate and cool the gears.
The timing belt coordinates the rotation of the engine's camshaft and crankshaft so that the engine's valves open and close at the perfect time. If it breaks while driving, the pistons will smash into the valves, completely destroying the engine. It's an expensive maintenance item because accessing it requires dismantling a significant portion of the front of the engine.
Transmission replacements are major repairs, generally ranging from $2,500 to $5,000+ depending on the make and model of your vehicle, and whether you use a rebuilt, remanufactured, or brand-new transmission. However, many "transmission problems" are actually caused by failing sensors, solenoids, or low fluid. Always let our experts run a full diagnostic before assuming you need a total replacement.
Yes! Many modern cars claim to have "lifetime" transmission fluid in sealed units with no dipstick. However, automotive experts agree that "lifetime" generally just refers to the duration of the factory warranty. The fluid still degrades over time. We have the specialized equipment required to flush and refill these sealed transmissions to keep them running smoothly well past 100k miles.
