Allison- filter change

Planning on changing the main filter on my Allison as part of the Transynd changeover I did 6000 miles ago. How much of the "liquid gold" can I expect to drain out when I remove the filter?

I have not done the oil change in a 4060 (which I think you may have) but on all other 3060s I have done it was around 4 litres plus along with the 2 filters.
Hope this helps.
6000 miles is a quick change as I think they say up to 25k?? IIRC

The only reason I was thinking about this is I was told, when it (transynd) was put in, that it would need to be changed out again @ 2500 miles and then it would go 25000 miles. This stuff is too expensive and being a frugal guy  I am leaning to to just change the filter and top off.

Rick, here is a Beamalarm link to Allison info,
http://www.beamalarm.com/foretravel-links/PDF/allison-transmission-filter-change-sa5429EN.pdf


and I think you have some incorrect #s in your post. I think it states after 6000 hrs to do a change then you should be fine for over 250000 miles . This is with High Capacity filters. Lots of figures in report so hope I am right. The other thing it states is it will need up to 8 ltrs on a filter change but when we did Geoffs coach a couple months ago it only lost about 5???

Isn't it a 75,000 mi change interval for Transynd for retarder coaches?

In reviewing the attached document and other Allison materials, it is my understanding that the initial filter change is limited to the main filter and not including the lube filter.  The special filter kit for this initial change only includes the main, so I believe that is what Allison intended.  With that said, you are only talking about 2 quarts versus 10 (2 + 8) for the dual change.  Then you revert to the longer term schedule.

In other Allison documentation, it is suggested that the initial main filter change can be avoided if using the high capacity filter.  Unless you know that a high capacity filter was utilized at rebuild point or Transynd install, it would be best to do the initial main filter change.

I'm suspecting that the main acts similarly to the primary fuel filter and catches the majority of stuff.  And that on a new or rebuild situation, Allison is concerned about filter capacity on that one.  If both filters were depleted, the transmission would be having more serious issues.  In reality, I doubt the main even experiences a pressure drop.  The only wear components should be the clutches and that shouldn't be much.
