At Harold's Used Auto Parts Inc in Philadelphia, PA, transmission maintenance and repair is our specialty. Here’s some information on your transmission pump - what it does, and how to know if yours needs to be replaced.

The transmission pump is an integral component of your transmission. If it’s underperforming, hydraulic pressure and lubrication are dramatically affected, which are the two necessities of a functional transmission.

You may notice a transmission that slips, overheats, or shifts unpredictably, at the wrong moments, or not at all. If you notice any of the above issues, stop driving the car immediately and have our technicians take a look - it doesn’t take long to ruin the whole transmission if the pump is going bad.

Transmission pumps are generally very reliable, but a few things can cause them to fail. Buildup or debris in the fluid can block small passageways, preventing lubrication and pressure from reaching vital components. The gears that make up the pump may also wear down over time, reducing the fluid pressure your transmission is capable of. More often than not, the whole pump doesn’t need to be replaced - a good cleaning and new gears will have it good as new again in no time.

No matter your transmission repair or maintenance needs, we’ve got you covered. For the best transmission service shop in Philadelphia, PA, call or stop by Harold's Used Auto Parts Inc today.
