Crawled under coach to drain tranny so I could fill it up with Transysnd. Pan drain rain plug --no problem--3/8 drive worked fine. Took a 9/16 and a 5/8 socket under with me in anticipation of changing the filters.
Nope. You guessed it.
15mm.
I can get under the coach and back just fine. It's my fat butt and belly that has the problem.
POOTIE, quick, bring me a 15mm 3/8" drive socket.Quote:

Didn't change the filters as they were new last August--just loosened the bolts to the filters so I could get a more complete drain.
Just another aggravation about having dealerships do stuff for you. Had asked that they install Transynd when they were doing the PDI--they didn't.
Told them I would pay for the Transynd vice their Dextron. It does get old.
My plan: I will change the filters some time next year, followed in about a year with another fluid change: That should pretty much complete the change over. In the Allison 4060 application one will loose almost two gallons with a filter change. I figure periodic filter change will take care of any residual Dextron.
Just for info, I let it drain for two days. One would be surprised how much more fluid comes out after the initial dump.
At any rate, I was surprised that the tranny was metric. Will add a 15mm socket to my carry list.
You cannot prefill the filters on an Allison six speed. They are a pleated type that are sitting on a plate. There are two filters.
What cannot be removed is the fluid that remains in the intercooler unless you start some serious disassembly.
