2006 Wrangler Sport - Transmission Problem??

Hi everyone, I hope I'm posting in the appropriate category. I'll get right to the problem I'm having with my 2006 Wrangler Sport, 4.0, V6, manual transmission. Any help would be greatly appreciated.

I use my jeep for the personal plowing of my driveway and a couple other family members. Last night, after some plowing, I could smell this awful, nasty smell - I'm pretty sure it was a not burning engine oil type of smell. I'm not sure what it was, but now I"m convinced it's the source of my problem. I first passed it off as some sort of hydraulic fluid issue since upon inspection of my plow, I saw hydraulic fluid leaking from my hydraulic lines and power box. So when I went to pull away and head home, my check engine light was flashing and I had lost a lot of power when trying to take off in all my gears. I would step on the gas and the jeep would barely respond and even wanted to stall out. It did stall on me once. I restarted it and when I put it into gear it was giving me very slow take-off with my foot plenty on the gas. The engine wanted to just keep stalling out. Since I needed to get it home (A VERY BAD idea, I'm sure), I decided to keep going. My thought was that the rocking back and forth while plowing got air into the gas tank and caused the engine misfiring and also the check engine light to flash (at least that was what I was hoping). After 10 minutes or so the engine didn't wan't to stall anymore and seemed to behave itself, but my transmission seemed to buck on me when I'd hit the higher RPM at the end of each gear (before having to shift). Then I started to wonder if I had transmission issues.

Check engine light continued to flash all the way home. When I finally got it home I turned the engine off and tried restarting the jeep. The starter was working great and the jeep was strongly turning over, but it just wouldn't start. 12 hours later same thing. When the key is turned in the ignition, the check engine light just flashes.

Fluid checks resulted in low engine coolant and power steering fluid. Added more engine coolant thinking there is some sort of sensor. Didn't help. I doubt it's the power steering fluid but will add more when I buy some. It wasn't that low, just needed some added. Engine oil level was perfect and clean.

Checked under the vehicle and no noticeable leaking from anywhere. Recently installed new front rotors and pads myself along with a new battery and starter. Front sway links are broken and I have those ready to replace, but can't see that being the issue.

Is the check engine light flashing making it so my jeep won't start as a safety issue? How do I find out what the code is to diagnose the problem? Should I reset the CEL and if so, how? What does a bad transmission smell like if it's going bad?

Sorry this is so long, any help would be appreciated. I don't want to take it to a dealer and have them charge me $$$$$ just YET.

Thanks,
Kent

I'm in central Texas so don't know about plowing...I assume you were in 4wd and if so high or low? Does the plow work off hydraulic fluid and if so, does it come from power steering? The check engine light will provide the code in the way it flashes. I have a code reader so not sure how that works. Can you get access to a code reader?

Thanks TexasT, I was in 4WD High. Yes, the plow works of of hydraulic fluid self-contained in the plow's main power unit that is unrelated to the jeep itself other than an electrical hookup. It's not related to the power steering fluid of the jeep itself. The check engine light just flashed on and off repeatedly and steady. It doesn't have a flashing pattern so to speak or at least I don't know how to check to see what the pattern is. How does your code reader work - hook into? I heard Advanced Auto Parts will check your code for free (or maybe that was to just reset it). Thanks again.

loosing coolant? maybe you blew a head gasket?
flashing CEL means engine is misfiring.

To check codes turn your ignition key - On - Off - On - Off - On and the code will pop up in the odometer display. Plowing in 4wd-Hi is rough on a plow vehicle. When I used to plow I would drop it into 4wd-Low. It doesn't put so much stress on the transmission and especially your clutch. You may have smoked your clutch but not sure how that would prevent your vehicle from starting. Bad transmission will smell very strongly of burned oil. A burnt clutch smells horrible, not sure how to describe that smell. Don't reset the codes either. If you take it into a dealer those codes will help the technician diagnose the problem.

On my 05' I turn the key - on - off - on - off - on and it always pops up in the odometer display. I know it is different with older Jeeps.

It sounds like your computer went into limp mode which will kill all your power. When the MIL lamp is flashing it means severe engine and or cat damage has already or is in severe danger of happening. Don't attempt to drive the jeep for any ammount of distance as this can cost you major headaches and money. Have the computer scanned to get the code or do the odmeter trick to find the code. Your probably gonna get at least one misfire code and possibly some others. Check to make sure all your injector plugs are secured and check your plugs for fouling. I had this problem with my 97 with the 2.5 and it turned out that the number 1 and 3 injector plugs went bad and needed replaced which was only about 30 bucks for parts. Hopefully your problem is only something minor like this. Best of luck.

I THINK holding the trip reset checks the gauges, and not pulls codes?

Thanks everyone on the code advice.
Before I received all your replies I talked to Advanced Auto Parts and they told me that the way my CEL was flashing I'd have to take it into the dealer and have it put on their readers. Not good I thought. So I had it sent to the dealers last night and am awaiting the dreaded phone call and $$$ issue. Or maybe I meant to say, $$$$$$$. We'll see I guess. I think the clutch is one issue and that's about $150 to put in myself I think. Anything else major then I'll probably have let the dealer take care of it. I'll post back when I hear more about what is really wrong. Thanks for all the replies. Nice forum.

Dealer just called me and said the Cam Shaft Sensor and the Throttle Position Sensor were bad. He said that is what would have caused the "bucking" and the loss of power when in gear. $318 to replace both and includes labor. Maybe that's something I could have done myself a lot cheaper, but I have to say I'm glad something major didn't go wrong. I was thinking 3-5 times the cost.

He also said I didn't ruin anything by driving it while the CEL was flashing. Nothing mechanical, just malfunctioned sensors. I'm glad about that too.

Doesn't fix the "smell" issue, but if it is the clutch and it ends up going, then I will give that one a whirl myself.

Hopefully after they put the sensors in something else doesn't come to light.

Thanks for your help everyone.

I have a 2007 jeep wrangle 6 spd, I tow a small pop-up camper once and only once a year. For the 5th time since I bought it, everytime I back in up into my driveway my transmissions gets this horrible smell like rotted meat. It last for about 3 hours and is so bad that Flies are attracted to my Jeep. This is not a joke, I have to warn my neighbors everytime I come home. Has anyone else had this problem? Other than that I love the vehicle.
