Only real thing is the secondary chain guides wear quickly on those (all the 4L's). If you go manual you'll avoid the entire radiator/transmission fiasco. I've noticed the chain guides last about 100,000 miles before they start to whine. Its a rather long job but if youve done a belt/chain before it shouldnt be so bad. Other than that it's your normal wear and tear items. It's a shame they stopped making them.
