Allison 3000 fluid change
Just curious if anyone has had an Allison 3000MH fluid and filter change with TES295 recently? I was quoted $875 for changing both filters and draining/refilling with TES295. I already have the TES295...

Fire Up,
No disrespect meant, but if you re-read my first post on this topic, you will see that I am not changing over to Transynd. I am already running Transynd. My quandary is whether to change out all the Transynd at 90K miles, or only do a filter change and top off the lost Transynd and perform an oil analysi. Or, just change the filters and all the Transynd, and not worry about it for another few years. My prognostics tell me that neither is due right now, OL 78% OF ok, but Allison states that on MHs you can't go by the prognostics, as we don't run a heavy enough of a duty cycle for the prognostics to be accurate. My last and final question is how much fluid do you lose only doing a filter change? If it is a couple of gallons, then the difference to replacing all the fluid is really not too much more.
This quote from another forum seems to indicate the fluid loss may be close to 2 gal. If you decide to change the fluid as well as the filters now, I would still council you to do the sample test. Beyond giving you an idea of the condition of the fluid, it also reports contaminants and wear metals which indicate the health of the transmission itself. It's exactly like a blood test during a physical. It's not just about the condition of the blood.
"You'll get maybe a quart from the main filter and up to 2 gallons from the lube filter depending on fluid temperature."
This was from Tom Johnson. Another quote stated that the poster changed filters with the fluid cold & lost less than one gal.
I guess total fluid loss is not as definitive as I thought it would be.
