Installing one of these external spin-on filter kits into your automatic transmission cooler circuit just may the most valuable move you will make! The “micron rating” of the internal filters in most (if not all) transmissions is horrible, ranging anywhere from 100 to 200 microns. These external filters are down in the 21-micron range and flow at least 7-9 gallons per minute with no restriction. These transmission filter kits are readily available under several brand names. Of the three I have used in the past, this Derale kit is definitely the highest quality.
Just to let everyone know, the filter itself is a very common size, readily available from your local auto parts store under a dozen different brand names, and for about half the price of the Derale filter number 15092. (which BTW is a Champ PH253) So just pick your favorite brand of filter, and tell them you want the exact replacement for a Champion PH253. OR BETTER YET, if you have the space to use a larger filter, then just use the NAPA Gold number 1515, Ford FL1A, Fram PH8A, or whatever brand you prefer. That filter’s specs are better than the smaller ones, PLUS you will have about 3 or 4 times the filter media surface area. And it is such a common number that it will likely be half the price of the small filter. You will have a superior filter for less cost. And if you want really superior filtering, then select a replacement filter with the same flow rate, bypass valve setting, etc but with a much finer micron rating in the range of 15, or 10, or less. (such as WIX 51307, or 57088, etc)
The next time you need to change your transmission’s oil and filter, you will be SO GLAD YOU INSTALLED THIS KIT. It makes it nearly as easy as changing your engine oil and filter. -even with no drain plug on the transmission, all you need to do is: 1. Remove the spin-on filter, place your drain bucket under the mounting plate, start the engine and let it idle until the fluid flow stops, shut off engine. 2. Measure how many quarts were drained, re-fill the trans with the same number plus a small additional amount for the filter. 3. With new filter and replacement fluid installed, run the vehicle until the transmission is fully warmed up, recheck the fluid level, and adjust as necessary.
I've done this procedure now for over 20 years on four different vehicles (all GM) about every 20 to 25 thousand miles. The transmission fluid always stays nice and clean, there are never any visible wear particles or debris in the drain oil (they are all trapped in the filter) and it gives me a lot of peace of mind. I suspect I will never have any transmission issues on any vehicle.
