External filter change

You say you use others in a pinch. Do you change it out more often like every second engine oil change? I change my engine oil every 5k miles.

I change my spin-on every other oil change (10k miles per trans spin on change) because of how cheap they are and there isn't a situation where you can really change the spin-on too often. I change my internal/fluid every 2 years/50k miles but that is a bit excessive.
I've used a local parts store brand, gm, etc when doing a service and I mess up and am out of stock on Allison filters (I usually stock a case) and need to get the service done on my own vehicle. Conveniently it only happens when I work on my own junk and not anyone else's.

if I'm not mistaken, you want to make sure the aftermarket filter's ports or holes match the Allison filter. I believe some if not most are positioned different and get partially blocked when installed restricting flow. also, don't forget to save the magnet and transfer it to the new filter
Now you have me wondering about the holes as I just changed it. I picked up a WIX 57701 at our local Piston Ring. I googled pictures and it shows 8 ports vs the Allison’s 6. I did clean and transfer the magnet. The NAPA Gold 7701 has 6 holes which cross references to the WIX 57701.

I saw those in my research and wouldn’t want a filter sticking out lower than the pan itself.

Problem is the Allison spin on is 27 micron for a reason. It allows proper flow for the solenoids and valvebody. After market spin ons are 15 micron which can act like a partialy restricted filter and may cause improper shifting and damage to the clutches.
Depends on flow. I have never tested it but will as I have an adapter to check flow on spin ons. We need to see 125 psi going in and out max. Any more will get dumped to sump by the control main valve. Any less will cause big problems.
My head is spinning lol. I’ve talked to two guys about filters just now. One buys the NAPA Gold 7701 and another buys ATP B201’s from Rock Auto. Both have never had an issue using these filters. Both are longtime Allison owners.
I’m going to run this WIX filter then next engine oil change I will install a genuine Allison filter.
Thanks for everyone’s input!

I asked being a newbie to these transmissions. Information gathered after me posting has led me to believe AM filters can’t be that bad using them long term. I may just pickup an AC Delco one from our local GM dealer.

Why wouldn't you just use the Allison branded filter like has been recommended by various people? Seems kind of backwards to ask for advice then say "meh, I don't need it I'll just use what I can get forever'.
Buying Allison branded filters isn't hard, there is usually an Allison dealer close, Amazon, any of our major forum vendors etc can all get them.
I’m in Canada but just ordered two Allison brand filters from Amazon.ca for $33.49 each CDN bucks.
Thanks for your input.

I didn’t say that! The more advice you ask for the more you’re going to get a different answer. You yourself said you have used other brands in a pinch with no issue.
