Allison 3000 transmission
I had my Allison 3000 transmission oil changed to Trans Syn synthetic fluid at 34,911 on 2/12/15. I have now just under 50,000 miles and my question is should I have the transmission fluid changed aga...

Allison's new generation fluid Transynd TES 668.
It supersedes Transynd TES 295 and is backwards compatible.

Stick with the change interval based on your current fluid's recommended change interval which is affected by Allison's duty rating. Allison classifies any transmission with a retarder as "severe duty".
And, when you do change, go to the improved TES 668. I visited with Tom Johnson who helped develop Transynd TES 295 and he highly recommends going to the TES 668 at the next change interval as the additive package is even improved over the TES 295. Basically, there have been strides in chemistry over the last decade! Take advantage of them.
