Clutch overheating warning

[Rahkmalla]

As I've said, I wasn't using my head, just enjoying the lights. It's on me, I know that.

I think what many are calling into question here is why you would abuse your clutch then issue a "warning" to others:

Just a warning to the guys with the 6 speed. Be careful over using the clutch.

I understand you've acknowledged the error was yours and not your Jeep's, but the original post is still a "warning" post, when follow up has revealed you were using your clutch to hold your jeep in place on a hill (there are brakes for this you know?), using the wrong gear for super low speed cruising, and purposefully slipping your clutch the whole time.

The automatic transmission equivalent would be posting a 'word of warning' to the automatic guys out there about not repeatedly neutral-bombing your transmission. Well yes, most people already know that abusing the equipment won't have a positive result.

I guess most of all i take issue with the post title (since most people read headlines and little else). Yes, a clutch will overheat if you engage in a series of behaviors that specifically heat it up.

Well, I learned something from this thread, so it wasnt a complete waste, lmfao!

A similar warning/suggestion: I used to downshift 4-3-2 going into red light stops. Now I just hold 4 until approaching 1200 rpm or so then go right to neutral for the last few car lengths. Why the difference? Syncro wear. I've worn out 3rd gear syncros before. Brakes are cheaper to replace. But on a long mountain downhill I'll gladly downshift for engine braking.

Well, you should be rev matching for your downshifts to help prevent excessive synchro wear.

Somethings going to wear, brakes, clutch, trans, so picking your poison is key, based on the repair cost/time.

Some people go for "fuseable links" as in a mechanical sacrificial part thats easier to replace/repair then beefing up everything to have any failure be a serious one.

Lots of different trains of thought on these subjects.

I downshift rev match, lil throttle blips, and am kinda excited to eventually put a heavier clutch in the truck. Oem has poo poo feel for engagement.

Rev matching prevents synchro wear as already noted, but the real reason for not excessive downshifting is gas savings. Coasting to a stop, your engine cuts fuel. The connection to the wheels is what keeps it turning. When you shift your engine has to supply fuel again for a period until its been coasting enough again. My normal coast to a stop gear is 3rd which i take down to 20mph or even a touch lower. Watch your current economy number while coasting and downshifting, you'll see what I mean.

First time tonight. Was at High Point University christmas lights drive thru. Cruising through the campus in 2nd gear, up and down hills. There was alot of stop and go traffic and I was riding the clutch (probably shouldn't have). About half way thru, I got the clutch overheating warning. Stated for me to let out clutch and use sparingly. Was able to get it to clear after babying it for about 5 minutes or so. Did smell the clutch so to speak. Lost my sense of smell last year.
Didn't think I'd ever see that warning but there it was. I did have the pcm flash last year on this. Drove fine after I got out of there. Just a warning to the guys with the 6 speed. Be careful over using the clutch. Have a great night.

Did or didn't smell the clutch? Typically the "overheat sensor" exists in the olfactory receptors and a warning indicator would be down right silly. Unless this was added by Jeep due to covid ; )

Yes! I've taken note of the mpg clutch in and downshifting.

This same question entered my mind. A burnt clutch is very smelly, and lingers a long time.

Ugh, I have smelt mine a bit when I first got it. Smell of shame. Im too used to heavy performance clutches with actual feedback, and an engine you can actually hear lmao! Its all sorted now though. A littke learning curve

Lost my sense of smell last year because of covid. Go figure.

How's your JT clutch holding up now after the incident? How many miles on the odometer?
The reason I am asking is to determine the durability of the stock clutch. Whether I should wait for the Centerforce Clutch till the stock one shows signs of slippage or to do it now.

I have had no other issues since the night this happened. My mileage is at 19,356. The clutch is holding up well. Feel and operation have not changed in any way. If and when the clutch begins giving real problems, I'll opt for the centerforce replacement. Until then, I'm happy with the stock clutch.
