Getting ready to do the initial Transynd change in the transmission. Looking for info as to ball park prices to do it. Found a Stewart & Stevenson shop in Panama City Fl. 60 miles from my house.
$563 for fluid and filter, $132 labor at MOT in 2011 during a maintenance special, so about $700 total.
$450 for RVMobilelube.com (operates here in Texas) for filter and the first 6 gallons of Transynd, $50/each additional gallon so about $600 total.
You will want to price a PAIL (5 gallons). That should leave you with about one quart left after a filter and fluid change in an Allison 3000.
My transmission took 13 gallons of Transynd.

We had our transmission serviced at FOT in August 2014. Transynd, filters and labor, $609. Our Transmission is the Allison 3000MH.,

But the OP has an Allison 3000, not 4000.
$43 a gallon, not sure if that is good price or not? http://www.merchant-automotive.com/p-2984-transynd-full-synthetic-transmission-fluid-1gal.aspx (http://www.merchant-automotive.com/p-2984-transynd-full-synthetic-transmission-fluid-1gal.aspx)

We switched to Transynd at Interstate Powersystems in Bloomington, MN. summer before last. 1/4 mile from Mall of America while you wait. Flush, fluids, all filters under $500.
Change filters every 12K miles. Probably. Never change fluids again, at least in my lifetime.

My goodness, I hope you're around longer! Transynd change is recommended every 75K OR 36 months,
whichever comes first
Yes, Allison classifies retarder use as severe duty requiring Michele's replacement schedule.
That is interesting. The Allison Service center (interstate) said much more than that even under heavy duty use. Maybe with a retarder it is more often. Even at 75K miles it will be a long time, maybe 10 years. Even then it is a very cost effective change.
Thanks for the heads up.
This helps...

It's 75K OR 36 months,
whichever comes first Barry's site has this Transynd Fluid change interval (http://www.beamalarm.com/Documents/transynd-fluid-change-interval.html)
Roger might have been thinking of what the former Allison engineering,Tom Johnson (hzjcm8), posted: Transynd Service Intervals (http://www.foreforums.com/index.php?topic=13183.msg72210#msg72210)
I went back and looked at the paperwork from my Transynd change. The Allison guy and the paper show that for the 4000 sries tranmissions under severe duty the change cycle was 150,000 miles or 48 months. (I should live that long). Severe duty included any retarder.
So Foretravel's service bulletin is probably on the conservative side whch is OK. Even at 36 months it is still better than regular fluid at 12K/6 months.
And I do fluids analysis at leat once a year. A coolant leak into the transmission is an expensive repair.
Thanks for the heads up. I had not seen the FT service bulletin.

How do you sample transmission fluid?
best, paul
I had my ATF tested. The lab also sold a kit with a pump and hose for sampling. You can re-use the pump, but the hose gets tossed after one use.
I searched Allison and found the Allison service bulletin covering Transynd and think I see the issue causing some discrepancy. Allison says 75K/36 months for severe service FILTER change and 150K/48 months for severe service FLUID change. Filter and fluids technically aren't on the same schedule, so the simple solution for FT is to recommendation to change both at the lesser interval of 36 months.
FAQ-Service Tips (http://www.allisontransmission.com/parts-service/faqs)
I would hardly consider motorhome use (which is mostly highway miles) in the same category as severe service transit busses and garbage trucks, which start/stop thousands of times a day and heavily use the retarder. Highway miles with no shifting and a locked torque converter put little to no wear on fluid/components.
But, it's not my $500+ per oil change that is getting spent, lol.
According to my Allison Manual, the 48 month fluid change interval is for transmissions with High Capacity Filters. The 36 month fluid change interval is for transmissions with Gold Series Filters.
What year did FOT change to High Capacity Filters?
I just looked up my service records from FOT. The filter kit used was part number 25948988. Research on the internet determined that this part number is a High Capacity Filter.

My 95 U320 with M11 has a Jake Brake. Can I assume that this does NOT enter the extreme duty classification?
Correct. It is the presence of a transmission retarder that ups it to severe duty.
