Hi all,
I've just joined Good Sam Club. I was the former Transmission Fluids Engineer at Allison Transmission. I held that position from 1990 until my retirement in 2009. Let me know if you have questions about TranSynd, the TES-295 specification or just anything to do with automatic transmission fluids. I'm here to help.
A friend of mine has a 1999 prevost and says Marathon when the unit was new changed the allison trans oil from Dex111 to 15/40 synthetic motor oil?Is this true?
