Crewman Cross8 clutch

The 4L65 transmission on my 2004 Holden Cross8 has just lunched itself after only 67,000 km, the dealer says it has destroyed the clutch packs on three of the four gears. I bought it to tow and with some plans of giving it a hard time, but it has only ever been driven conservatively and hardly ever towed anything. It?s out of warranty, obviously, but surely Holden can't expect to sell cars that only last 67,000 km? I have a quote from a performance shop that, for only $800 more than a reconditioned unit, will fix mine and they say it's bulletproof and they give a 2-year unlimited km warranty. Would Holden consider some compensation even though it is out of warranty? I guess they wouldn?t if I was going to have the performance shop rebuild it, would they? Is it worth approaching them, if so how should I do it?
