Resolution to Overheating Auto Transmission "HOT OIL" Warning

To all of you who followed and/or commented on my posting in early April where I had a "HOT OIL" warning pop up on the instrument cluster and smoke under my JK (symptoms of an overheated auto transmission) while driving in 4H on the beach, last week JEEP released Service Bulletin # 07-002-10 (Group: Cooling) that carries a date of Feb 16, 2010 which is when its drafting began.

SUBJECT:Heavy Duty Transmission Cooler Kit
OVERVIEW: This bulletin provides part information and installation instructions for a newly released heavy duty transmission cooler.

My JK is in the shop now having this installation done. Hopefully it will eliminate the potential for the auto transmission to overheat during use that this JK is marketed and intended to be capable of.

Sweet.
Are they paying or you? If you, how much?

My trans overheated twice during my road trip to Arizona and back. Both times were on pretty steep hills, 65-67 degrees out, paved, 40-50 mph, with my trailer in tow.

I think the only way you'll get it free, is by having failure of the auto under warranty-or if Chrysler decides to make the aux cooler a TSB issue and I doubt that that'll happen

Maybe a dumb question but does the tow package already have a tranny cooler?

They all have a trans cooler --- I was just wondering if he got a free upgrade due to a tow package.
I'm definitely going to try and get this done.

I talked to Chrysler TSB center yesterday and they have never heard of any bulletin(7-002-10) for an additional (AUX) cooler and no TSB is being issued !!!

Just put one in it's easy, makes all the diff. in the world and I even put temp gauges to show the auto "hot fluid out" temp and return temp, after being cooled

Sometimes ya just gotta bite the bullet !!

Thanks Pokey. Issue resolved for the time being. Pix of my daughter (no sunglasses) and friends at the scene of the crime. Pix of the new transmission cooler. JEEP had to tear down transmission and rebuild as well due to internal heat damage replacing numerous internal components. Thanks for encouraging me to stick with it.

Congradulations-That cooler looks like a BIG ONE, I wonder why they put it so low-sense you don't have an A/C condenser ??

Mine is near the top of the grill louvers, for better air flow

Anyway, good luck, the extra cooler makes all the difference in the world

awesome. every auto JK owner needs one. i've got a tow package jeep, and it's cooler sucks. i've got dinged once while offroad, and in heavy traffic it gets pretty hot but has never dinged at me. i'm installing one probably near the end of summer.

i heard if you install one of these and prove it to chrysler, they'll reimberce you. i dont know if that rumor is true, but it's worth a try. what's the worse that could happen? they say no? ohhhhh that's nothing new

You have have the TBS (J30), done by a dealer and certified---Then if you've already installed an aux cooler, prior to this point, you can send the receipts (copies) to the Chrysler Recall Customer Assistance--for your money

Othetwise--NO DEAL

wow! So it's true. So I need them to install the idiot light first at a dealership? I haven't done that. I just get a "mystery chime" but nothing lights up. I figured since that's not a real fix, I'm not going to bother. The only transmission issue I've been to the dealership for was torque chatter, TSB flashed under warranty. That chatter is back too.

Does the dealership need to install a cooler too? I was going to just do it myself.

You might be able to talk them into it anyway, but it won't be free--it's not a TSB !!

I didn't see your original post but when you have the Jeep on the beach be sure to air down the tires to 18-20psi. Not doing this really works the trans and suspension much harder than needed. In addition fully inflated tires leaves the ruts with washboards that will rattle everyone elses filling right out of there teeth.

Oh ok I get it. Wait till the trans melts, then Chrysler will hook you up with a cooler. After you pay 1000 bucks for a rebuild, they "give you" a $50 cooler. What a deal!

Trans probably overheated beacause you're running on the beach with fully inflated tires.

Hey look at the bright side, at least you didn't get stuck !!!

The TSB is out there. It has been confirmed by other readers as well Trust me. You just have to speak to someone at Chrysler JEEP who knows what they are talking about. They have a problem. They know it. Now they are trying to fix it.

An idiot light with a chime being installed isn't a fix for the 42RLE heat issue. It's just a way for Chrysler the day something happens that hurts or kills somebody Chrysler can say " hey! We installed a warning! It's YOUR fault your Jeep caught on fire and burned your family, not ours." Weasels.

Can't imagine why Chrysler went belly up last year. With exceptional customer service and customer satisfaction and all.

Oh well. At least our accelerators don't stick. Your Jeep just explodes into flames after you melt the transmission out. Actually, I'd rather the accelerator stuck. Maybe then I could get it up to 70mph

It overheats way too easily.
I overheated my trans twice with normal highway driving in cool conditions.
