Allison 1000
I know this topic has been covered in the past, but I can't seem to find the right answer. I am planning a change over to Transynd using the double drain and fill method. For the first drain and fill,...

To the original question, regarding the Allison 1000MH transmission. ONLY TES295 approved transmission fluids are recommended. D3M fluid is NOT TES295 approved. D3M fluid specs
So the choice is yours, use a non-approved fluid or use what the Allison engineers recommend.
TRANSYND (TES 295) is obviously the better/ and recommended choice for use in Allison Transmissions.
Most Allison's in use now come with or have been refilled with TRANSYND, however those remaining transmissions using DEXRON III equivalent fluids, licensed by Allison as meeting their TES 389 are using an approved transmission fluid.
As stated on the Allison website: "TES 389™ fluids may be used in traditional on-highway products but do not provide the same drain intervals or filter change intervals as Allison Approved TES 295®"
Your link to Petro-Canada D3M fluid indicates it is TES389 licensed and therefore is an approved Allison fluid..
edit..I should add that not all D3M fluids are licensed as meeting Allison's TES389..
TES 389 means D3M is an approved fluid to replace Dex III, not Transynd. As I said, you can use what you wants but Allison recommends a TES295 approved fluid made by several different manufacturers. Since the TES 389 fluids certainly do not last as long in "severe" usage (most RV are operated at close to the maximum gross weight all of the time, thus severe service) why take a chance with a fluid that is only a few bucks cheaper? From the Allison site, it is more than just extended drain intervals. They say that:
Allison recommends that customers use an Allison Approved TES 295® automatic transmission fluid to extend drain intervals and enhance transmission performance and durability in all operating environments with on-highway products.
Granted TES 295 fluid does cost a few bucks more but MY transmission shifts better and runs cooler with it, as verified with my digital scan gauge monitoring transmission fluid temperature. Transmissions are expensive. Transmission fluid is cheap. I would rather use what Allison recommends than a less expensive fluid that I MAY be able to get by with.
