I just had the recall software update done yesterday. The Jeep drives the same. The 2 main things that I have noticed are that the gear is now displayed and the ESS no longer seems to do anything. I even tested it by idling in a parking space after driving to work today. I am happy about it, I never liked the ESS. Has anyone else noticed this change with the update?
Well if it took away your ESS then that's a piss poor excuse for a fix. It shouldn't take away a feature of the vehicle.
It's ridiculous the way jeep is handling this situation. The clutch is just made crappy. They should just put in better parts.

Ok, I was hoping that it was part of the update. I feel like the ESS never worked well with the manual trans. For example, If quickly shifting into first at a light, it would have trouble and flash a warning light. Plus the extra wear on. The starter, etc...

my ess has never done that as soon as you touch the clutch the engine should start. You need to take it in

Are you all confident that this software fix will indeed fix the problem? I guess time will tell right?
I've had no issues with my clutch slipping. Honestly i don't think i would know what slipping feels like.
I haven't had any issues thus far.

I'm having mine 'flashed' Tuesday. I'll reply afterwards. I hope mine shows the gear and the ESS doesn't do anythings!

Mine doesn't do it either. Agree, something is wrong.
Mine has done this. It was a freak circumstance where I let the clutch out in neutral as I was stopping at a red light when the light changed. I moved quick into first since I was still rolling at 1mph and I let up before the engine had fully caught, leading to a stall while still rolling at 2-6 mph. I don’t think there is anything wrong, its just a circumstance that the system isn’t designed to handle and can’t anticipate with existing technology.

I am still confused that anyone thinks they can fix this problem (if it is indeed an everyday regular use issue) with a software change. From what I've read on this forum, the rumor is that these software geniuses will do some kind of reverse calculation from what the traction control software does and deduce that if things are not rotating as they should, then s/w cuts back on power/torque. To get that kind of resolution from sensor and have it reliable for 10 years sounds a bit unreasonable. And then, the V&V (verification and validation) must be really complicated to make sure that and traction-control don't do battle in the software domain. I guess that's perhaps why the s/w is not available yet.

Would you not feel that much slippage (if you are not causing it)? And if you are causing that much slippage, perhaps an automatic is in your future?

Would seem to me that using non-explosive parts in their drivetrains is the 'right' solution. Until the s/w is available I will keep driving my IED (the proper way so it doesn't explode :):)).
the calculation is pretty damn straight forward the computer knows the engine speed (same sensor that gives you your tact), it knows the the output speed of the transfer case (same sensor that give your vehicle speed), and knows the the transfer case range (same sensor that lights up your dash in 4lo). So knowing those 3 items you can do tcase speed/(engine speed x t case gear) = transmission gear, and knowing that you have 7 fixed transmission gears if the calculated number does not equal a known gear you have spillage between the engine and tranny. There are a few edge cases you would need to rule out like neutral coasting and clutch depression, clutch position is easy and i am pretty sure they know transmission position according to the wiring diagram so you know if its in neutral or not

I really hope nobody blows up and dies. Then will FCA be required to replace the clutches?
I'm still considering a trade in.

Lisa, life is too short and no car is worth the kind of anxiety that you seem to be having. Sell/trade the thing and move on with your life.

ESS not working could just be a low battery situation (or maybe something that happens after a PCM flash?). The very same thing happened to me after a service appointment.. at first I was like "sweet! it's gone"... then after about 50 miles or so it activated again :(.

I wonder why they just don't replace the pressure plate and be done with it.
Why a software fix?
Yes, I have found that money is usually the answer to most questions. In this case I think they are bouncing risk and cost with the repair. I did talk to the folks at FCA. and I am convinced that the software will have a little impact for most in most conditions. I do not anticipate driving my two door manual any different.

no question. I am sure it is all doable, but then they still got the cold weather temperature sensor on the outside of the vehicle rather than on the inside :) o!!!!!!!-
