Hi folks, My name is Tom Johnson. I was the former Transmission Fluids Engineer for Allison Transmission from 1990 until my retirement in 2009. I worked to develop and release TranSynd for Allison over a 10 year period and I also wrote the Allison TES-295 and TES-389 specifications. I had full responsibility for approval of all transmission fluids for Allison products on a world-wide basis.

Since Allison was owned by GM for decades, and as part of my job at Allison, I also served on the ATF Committee for General Motors for several years. And, because Allison produces most of the transmissions for the US Army, I was also a member of the Engine Oil Review Committee for SAE Performance Review Instittute (formerly the Lubricant Review Institute. These are my credentials. I'm here to help with your questions and to settle any arguments concerning TranSynd, Allison fluid specifications, DEXRON-III, DEXRON-VI, oil formulations, etc. So, as long as I'm not absolutely flooded with stuff, I'll try to keep up.

PS: I couldn't be involved in these forums while in my official capacity at Allison but I always thought I'd get involved once I retired. I own my own oil and coolant analysis business now and do consulting for the oil and additives industry on the side. Thanks for your stepping forward. I guess the most common question would be; Is transynd the best route to take?

I recently drained my 03 and swapped to Transynd. Castaway, Yes. It's still the best option. Telll others to forget about DEXRON-III. They're no longer approved or monitored by any OEM, so I'd stay away from them.

DEXRON-VI is no longer approved either since Allison is no longer part of GM. Not just because they sold Allison but because now Allison has no voice in any DEXRON-VI changes that GM may decide to do. Thanks for your question. __________________ • 2003 chevrolet 2500 suburbanHd Lbz Duramax studded heads, modded cp3, stage V Allison by MaxdOut Batmo wheel Fass 150 pump,down pipe, manifold, merchants engine mounts, Efi-live DSP5 by MaxdOut Diesel.
