Took my Patriot in to address an electrical/transmission code that popped up after a day of off-roading the other day. I'm at about 124k miles and had the transmission filter and differential fluids services at 104k miles. The service manager mentioned a 15k or 30k severe service interval for the differentials and transmission (can't remember which applied to which) for towing/off-road use (I've unfortunately only been off-road 3 times since the service). I don't recall anything that severe being mentioned in the owners manual which I believe only mentions the 70k differential service and the 120k transmission service, both of which I've been doing about every 50k. Anyone else heard of this?
