I was invited to the forum by docj from another Good Sam forum. I retired from Allison Transmission (and GM) in 2009 and served as the Transmission Fluids Engineer for 20 years prior to my retirement. I was the father of TranSynd and I wrote the TES-295 and TES-389 specifications. I'm here to help answer any questions you might have on Allison Transmission fluid specifications and transmission fluids (or engine oils). How they get to market, how they're tested, how they get approved, what they contain, how they degrade, how to monitor degradation through oil analysis ........ etc, etc. etc.
Thanks !! I look forward to your interesting questions.
