Rivet was just having a bit of fun. No harm no foul.
I actually wouldn't mind building an on-board latte machine though. That would make for some cool trail talk.
I hear what you're saying on your experience, but just because you didn't see the issue in your location doesn't mean the issue isn't there. I've been building and wheeling Jeeps and off road junk for a long time. Engines, transmissions, t-cases, axles - I've done them all. Sometimes the factory goofs. In this case, they put the vent in the bellhousing. That was an issue that carried over from the TF999 used in both the CJ7 and YJ Wrangler! In 95% of Jeeps, it's a non-issue - but for the 5% who wheel harder than the rest, well the search tells the tale. Some of the other Jeep goofs are the CJ7 AMC20 rear axle, the Dana 35, vacuum disconnect Dana 30's, rear slip yolk driveshaft in a short wheelbase Jeep, etc....the list goes on.
