I have purchased a 2004 winnebago adventurer w allison 1000. The books have paper advertisement refering to trans synd fluids. The rv has 33,000 miles, 1 owner before me. Bought from a dealer. How do I tell if has dexron3 or trans synd. Work horse says use dex 3. Would a test kit for fluids work or is dex 3 in the 2004s.?
Coyote74,
I will try to monitor this forum more often. I had not been on the forum for awhile as it didn't seem to have much going for Allison fluid conversations. I'm here to help. So, ask away !!!Do an oil analysis and let me take a look at the results. Send me a PM and I can recommend a fluid analysis service. Unlike TranSynd (or one of the other TES-295 approved fluids), DEXRON-III fluids will lose viscosity and thin out over time making them subject to more frequent fluid changes. Workhorse may say DEXRON-III but don't use it. Most of them are
not licensed. GM no longer licenses DEXRON-III since the specification has obsoleted around 2006. I know .... I used to sit on the GM Automatic Transmission Fluid Committee. We approved DEXRON-III fluids for the US and World market. The committee began licensing DEXRON-VI fluids and GM obsoleted the old DEXRON-IIIH specification at that time.
My recommendation is to get the transmission fluid analyzed and then go from there. You'll need to use an Advanced Test Kit that includes both TAN (Total Acid Number)and FTIR (Fourier Transform Infra-Red) spectroscopy analysis. This will show if the fluid is an older DEXRON-III or TranSynd (or similar TES-295) fluid. Once you know for sure what's in the tranny, then you can make an "educated" decision based on scientific data.
Again, I can help with the fluid analysis but you'll need to send me a PM.
Hope this helps !!!
