ATS TC = SWEET. ATS TRANS = EXPENSIVE GARBAGE.
Sorrry. I couldn't help it. I managed to tear up an almost $5000 ATS trans (I distinctly remember expressing my emotion about ATS products a few months back). When we got it took apart, we found out it was nothing more than a a thicker drum, some parts were shaved thinner to squeeze in a few extra clutch packs, the very nice, but SCORCHED tc, and the freaking humongous ATS deep transmission pan. The planetary thing was FUBAR. Metal shards everywhere.
I couldn't tell you if the truck was abused before I bought it, but...the evidence leads me to assume so. I'd only had it for like 2 months. And like you said, that $hit doesn't break over nothin.
I couldn't believe someone paid that much for a trans that really wasn't much. The trans mech and I both were bewildered.
