Allison 3000 MH

[gwarshawsky]

I own a 2005 fleetwood revolution

I believe I have a Allison 3000. MH 6 Speed xmssn. Should I be using the TranSynd 295 or the Dextron 111

I was told only to use the TranSynd but my manual says use Dextron III

I a bit confused

Anyone out there familiar with what the proper fluid is.

Regards,

Gene Warshawsky

The best solution is to get the serial number off the Allison and call the corp office. They can tell you everything you want to know about that transmission.

There should be a tag or sticker near the transmission's dipstick / fill pipe that says words to the affect that the transmission contains TranSynd.

That age of coach should have TranSynd in the transmission. If you cannot find the tag/sticker, then do as Cat320 suggested and call Allison.

Is there any type of sticker inside the rear grill? My coach has a sticker that says the tranny was filled with TranSynd at the factory, and to only use TranSynd.

I've never seen anything called Dextron, You can find Dexron almost anyplace though.
I would think TranSynd would be in your trans. although that is up to you MH manufacturer as to what they spec'ed to the chassis builder. The trans was tested by Allison using TranSynd, then drained as much as possible and sent to the chassis builder where it would have been filled with whatever the build sheet called for. Call Fleetwood to find out for sure although there should be a tag near the filler if it has TranSynd.

Dexron III is no longer made and would be hard to find. Nobody can get a license to make it.
Only thing available will have on the bottle as "Dexron III compatible"
Same bottle may also have "Mercon V compatible" and maybe other compatible's.
Or may have, meets and exceeds the performance requirements for the specification.

Allison recommends to change Dexron III fluid once a year.
Allison recommends to change TranSynd fluid every 4 years.

All DEXRON-III licenses expired at the end of 2006, and will not be renewed. Beyond that date, General Motors will only support the use of DEXRON-VI fluids for use in Hydra-Matic transmissions.
Fluids claiming DEXRON-III type performance continue to be sold under abbreviated names such as Dex/Merc and D/M, however, since the DEXRON-III licensing system no longer exists, these fluids are not regulated by GM in any way.

I was attempting to point out that there is no such thing as Dextron,the correct spelling is Dexron

A 2005 chassis would have come with Transynd (TES 295) as the factory fill. Both Freightliner and Spartan have been using a TES 295 fluid since around 2002.

My 2004 American Tradition came with Transynd - there is a sticker right by the transmission oil filler tube.

Tom Johnson, a former Tramsmission Fluids Engineer for Allison Transmissions who worked to develop and release TranSynd, and is now retired since 2009 had the following to say about which fluid to use: "TranSynd is still the best option. Even though Allison changed seal materials to be compatible with DEXRON-VI, TranSynd will last longer and remain more stable over a given time period." This came from the website: www dieselplace.com, in a forum entitled "Allison OEM". Check it out. It's good reading.

No need to go elsewhere - Tom Johnson is right here on iRV2.

I know it is probable that you already got the answer but, I have a 2005 Mandalay with the same transmission and Allison told me I have Dexron III fluid installed. However Allison does not recommend that that fluid be used anymore. They recommend that a full oil change & filters. The current fluid to use is TranSynd.
