Is there a much better spin on external filter for the Alli than the Allison filter? One that would do a better job of filtering out any clutch material particles?


Thanks.

SPX and a few other aftermarket filters are avail, but I doubt they do a much better job.. Most tranny's dont have half the filter the allison does as it is. I think a good way to improve it is with a filter mag or similer

Eric,


I thought I read somewhere that the Allison spin-on had a magnet included, can you clear that up? I'd check myself, but since I fear transmissions (I'll tell you a story about my Impala some time) I'll probably have the dealer do stuff to that magic box.


Thanks,
Dennis

I like the Allison filter better than the Baldwin. The magnet seems to completely cover up the holes on the Baldwin filter, where the Allison filter leaves all the holes exposed for less backpressure on the pump.

http://www.dieselplace.com/forum/smileys/Big Smile.gif FYI An engineer at Baldwin confirmed what I had heard - Baldwin does not make the BT8460 Allison filter. They have them made to their specs by someone else (very common in the filter industry). Who I don't know. Not enough sales volume to justify producing them. The Allison filter is a little cheaper than the Baldwin - both are good. http://www.dieselplace.com/forum/smileys/Thumbs Up.gif

I had the Baldwin BT8460 and the SPX 75T759 side by side.
As far as I could tell, construction of each was identical. The print on the bottem of the filter, (maybe serial number), looked identical.
These SPX / Baldwins have eight holes, approx. 7/32 inch dia., which are mostly under the magnet. The magnet rests against the crowned surface of the filter, so the holes are not covered tight. This crowned surface may allow more magnet surface area in the flow path.
The Allison filter has six holes, approx. 13/64 dia., which are located outside of the diameter of the magnet.
I would think only a flow test would tell if any filter is more restrictive or not.

Hey Steve, you got too much time onyour hands manhttp://www.dieselplace.com/forum/smileys/HiHi.gif

Who online, sells either at a good price? How often should this filter be replaced. Have 8,000 miles on truck. Is first change sooner than regular schuleded changes?


Thanks xsheepherder

i handle the Allison filters, www.kennedydiesel.com (http://www.kennedydiesel.com) handles the Baldwins

This may be a silly question, but what is the "magnet" on the Allison trans spin on filter and what is it's function?? Saw it for sale on the www.gmdieseltech.com site and also spoken of on this thread. Does it ever need replacing and is it something you would transfer to the new filter when changing it?? Why would you need a spare?

Thanks! First diesel - so much to learn and little time

Forget about my previous question - found the answer in another post and in the FAQ's on the Allison site. Thanks anyways!!

Sheeez - there's alot to learn when going from a gasser to a diesel!!

I use SPX in my shop.
