Filter brand - Fleetguard or Donaldson?

[CountryFit]

next month would be the completion of 4 years since my last transynd change over. i made a note at the time saying 150kmi or 4 years whichever comes first (somebody said 5 years?). the filter is a 2" filter kit, p/n 29548987.

two brands catch my eyes - fleetguard and donaldson. price-wise donaldson is about $10 cheaper than fleetguard. does anyone know which one has a better quality than the other?

(i'd pass fram, baldwin, hastings, and lumberfiner. this doesn't mean they are not as good; just not familiar with them or don't feel comfortable with them).

My input is neither. I'd stick with the genuine Allison filter. I've seen too many non-Allison filters sucked up against the control module and collapsed, or restricted flow due to inferior dirt carrying capacity.

I concur. These Allison's seem to be bulletproof when properly maintained. The 2 filter kit has all the correct O rings & gaskets and torque values for the filter cover bolts and drain plug. The kit should be under $50 at an Allison dealer.

I agree. Allison never conducted any field tests on any aftermarket filters. Allison spent tons of money and engineering resources developing the "High Capacity Filters".

I personally prefer fleetguard. Donaldson in South east Asia made in Indonesia.

Be sure your magnetic washer is included in the kit.

the job is done. i used allison filters, but i don't remember there were any magnetic washers come with.

There should have been one on the old filter. Did you re-use it...or did it get lost ?

[CountryFit]

bumber! i trashed the old ones.
but this was not the first change. 4 years ago i might have had lost it already :-(.

The magnet is on the spin on filter used on the 1K/2K series only. The Allison high capacity filters used in the 3K/4K transmission control modules do not have any magnetic washers.
