Recently had my Allison AT542 serviced by my diesel mechanic. Rather than the Transend, he recommended the Amsoil synthetic transmission fluid. His primary business is performance diesels.

since im not home right now, dont know which allison it has.
however when i did my walk around, it has a big sticker that the dexron 2 fluid has been replaced with engine oil (15-40).
the dealer indicated that a lot of coaches did this to have smoother shifts?
is that because of dextron2 vs newer dextron 3, or transynd?
better to just leave it, or upgrade to transynd?
