Interesting to see that Allison highlights on the cover both the 2nd generation fluid, Mobil Delvac Syn ATF, alongside of the 1st generation fluid, Castrol TranSynd

That's the same info that is in the sticky at the top, except in "brochure" format.

that transynd is liquid gold...i dumped 80 bux worth of it in my tranny, and my temps are down over 50 degrees.....ill run it again
