bullcrew Had a buddy look like he was burning up on a trail we were running....ran back with fire extinguisher s and sprayed before looking being the dry brush...


Was his clutch, needless to say he needed to be towed home and have it replaced...so they do smoke its not the first time I've seen it, saw it the last coup,e weeks with the manual guys on the nastier stuff...

rdseefeld It's probably the clutch. If you feather the clutch when backing up to control speed the clutch slippage causes a really awful burnt clutch smell. Mine did the same thing when reversing up a small grade. I found that putting it in 4 wheel drive eliminated the problem.

It's not. Unfortunate, but that's what aftermarket is for

bullcrew awful smells in reverse!

Mine did that then I realized I farted recently and shuffled around to look backwards....

WXman Yup it's the clutch. Mine did it Friday backing into my driveway. I was surprised at how in just a couple of seconds the clutch started stinking. Must not be a very robust clutch disc.

I would take it to a dealer, but currently traveling for a conference, and I got a 500 mile drive to take it back to the original dealer.
Pretty sure you're smoking the clutch. Mine still does it with over 20k on it on reverse up a hill if I'm not careful. These JKs don't reverse well up a hill in 2H.

It takes that long for the cat to get up to temp. It WILL go away. Eventually.

BakedInMN "Awful smells in reverse"
Is it kind of a sulphur smell? This is only a theory mind you but, perhaps you expended/released some "methane" when you were in the Jeep. The natural place for the fumes to to accumulate in the rear area of the cab. The nasty olfactory sensation you are experiencing is the , uh "methane" molecules causing the gas to rush from the back seat to the front seat, assaulting your senses.

As far as the issue my 12 is right around 3000 miles and I did get that smell for quite awhile even after the first 500 miles.

SinesPointToYes As far as I can tell, there is no fluid leaking.

The clutch could certainly be slipping because it's so new and tight, but I don't think I ride it any harder in reverse than going forward.... I've pretty much driven standards all my life, so I wouldn't think that would be a problem.

If its the catalytic converter, would I smell It if I just revved the engine in neutral? Just trying to figure out if this is the issue, any way that I can be sure?

Thanks for the help so far. Just trying to figure out if it's a problem or not.

Con Artist I've always been absolutely horrible at backing up with a manual transmission. It doesn't matter the vehicle, I always wind up with "clutch stink." It seems like when I let out all the way on the clutch instead of "riding" it in Reverse, the vehicle just shoots back at a really high speed.

Anyone have any pointers on how to back up SLOWLY while OFF the clutch?
07-29-2012 09:43 PM
Afmcronnie Its the catalytic converter breaking in. You smell it in reverse because you are driving through the exhaust plume. Mine did this for about a month. It goes away. Slowly...

kik It could be a few things. If you're sure you have no external fluid leaks. If not you could be leaking fluid internally on your clutch and the odor would be the fluid burning off. Or, you might have just rode the clutch a bit hard backing up the hill and you wore a bit off which would smell like burning brakes also. But, you said you've noticed it before that. Or, your e-brake isn't fully releasing and you're getting the odor of burning brakes because of drag. You can take it to the nearest Chyrsler dealer. It doesn't have to be the original dealer as you know. If it is fluid leaking internally you definately shouldn't be driving 500 miles.

SilverSport The burnt smell is likely from slipping the clutch. The friction material on the clutch disc overheats.

Spro12JK Mine had a burning smell for about 3 weeks. Didn't notice it in reverse though. As for taking it to the dealer you don't have to take it to the dealer you bought it from. You can go to any dealer.
