Title: Allison tranny filter change
Post by: Don and Kathy DuCharme on July 29, 2012, 02:01:09 AM

I am about to change the filters in our Allison 3000MH transmission, and am curious as to how much fluid I will lose in the process. We have an 07 Contessa with a Cat C9.  All help will be appreciated.  Thanks.
Don

Donald,
Let the coach set on a level surface long enough to cool down and you will normally loose from one to two quarts if you only change both filters.

Thanks Gerald, I thought that was the case, but received conflicting information from other sources.
