Don't know if I posted this here or not.... I have a 2006 commander limited and have had the intermittent gremlin 'trans over temp' warning for a few years. I've tried to research it best I could. Many people just said forget it and put in a manual temp gauge so they could be sure of the trans temp. I recently looked all over Google on how to replace my alternator but it seems to be a big secret. I came across this guy who was changing his alternator too on his Jeep and he mentioned the trans over temp gremlin. Ok, what he did was removed the end of the airbox tube that goes towards the grill...the end piece looks like a deflector. He blew out the pins too. The trans warning hasn't happened since. Well, I'd piss on a spark plugs if I thought it would help so I figured out how to get to the alternator and while I was at it if drill out those two rivets and remove that deflector. I didn't blow out any pins. Proofs in the pudding.....the trans over temp warning, along with the jet engine fan coming on and trans slipping, has stopped. Here in AZ that warning would come on frequently and drive me nuts. Now my Jeep runs great! A/C full blast and zero issues. I'm not an engineer so I have no clue why that would work.
