The transmission is one of the most important parts of a vehicle. Without it, a vehicle cannot move. Transmission filters work by catching excess fluids and filtering out debris and contaminants before they enter the transmission. Finding the right transmission filter is essential to proper vehicle operation. Here are the best transmission filters on the market.

  • Best Overall
    ACDelco Professional Automatic Transmission Fluid Filter Starter Kit

    The ACDelco transmission fluid filter kit is very popular among GM car owners and mechanics. It features an air-tight seal, felt filters, and fiber filters infused with resin.


    The transmission filter comes in a kit equipped with everything needed to get the job done. This includes the filter itself and the tube filter seal. The filter is the same as GM’s original filters and will stay in place once installed.


    There are different size variations, and the deep pan is not even across the bottom as one side is deeper than the other.

  • Best Value
    Allison External Spin-On Filter

    The Allison external spin-on filters are leak-proof and made specifically for certain GM trucks for a perfect fit each time.


    Genuine Allison filters are comparable to ACDelco filters except they’re half the price. These filters use a high-quality magnet and are expected to last up to three years.


    It comes with a magnetic disk, which you may inadvertently throw out, forcing you to order a new one. This problem is easily avoidable with other types of filters.

    This filter is made from durable metals designed for longevity and to prevent abrasiveness and corrosive moisture from entering the vehicle. The product features 20 bolt holes for a perfect factory fit every time.


    The Motorcraft transmission filter does not come equipped with other materials needed to change the filter, such as a gasket.
