I REALLY NEED SOME HELP

[Bptchris01]

I have a manual 2018 JLU Sport. It's all stock minus the 4" lift and 35s. When I hit the clutch to down shift or go into neutral 9 times out of 10 my rpms will almost bottom out then just about 1000 and then settle down. When I start it it will idle about 17000 ish. It will settle down if I give it time or I can pop the throttle and immediately drop to the normal 700. 1st to 2nd is ok. 2-3 can be a little weak(in my opinion). 3-4 is really weak and when I'm in 5th it will actually slow down even though I can have it floored. I've been told that it might have to do with the clutch recall. Before I beg and borrow to get a centerforce can anyone tell me if it's the clutch or not? I'm poor as hell and I can't spend $1500 just for hopes. This is my daily driver and I dont have anything else.

Do the RPMs climb after you upshift, as the jeep is slowing down? If this is the case, the clutch is slipping against the flywheel.

What engine, 3.6L? What gearing? Did this just start, or immediately after the lift and tires. I can't imagine driving a Sport, with 3.45 gearing (or whatever they have) with a 4" lift and 35" tires. That sounds like the worst combination you can have, so I'm hoping, sort of, that you've regeared to 4.56 or something already. If not, you f*cked up putting those tires and lift on without addressing the related drivetrain components.

Disregard if you've regeared. The tires are a large gear, at the end of the drivetrain. So, you have your engine torque, the transmission multiplying it, the t-case multiplying it when in 4-low, then the differentials with gears in there. The tire is a HUGE gear at the end of the axle. If you change tire size (the largest gear) without addressing the rest of the drivetrain to turn that HUGE gear, well, you're just doing something dumb, and it'll cause additional wear on your clutch and other drivetrain components. If you've already regeared, none of what I said applies. If you haven't, you need to address it. The lift just makes it worse.

It was this way when I bought it. I'm new to jeeping. Really new. It had the lift and 35s on it. It doesn't look like the pumpkins have ever been open. The paint is still on the bolts up top

I think the person that had it before you wanted it to look cool, but didn't address the performance. It may be something else, but I think you're starting with a bad configuration.

First - welcome to the forum!

Sorry you're having problems, but yelling in all caps "I NEED SOME HELP" is pretty rude anywhere. Instead, please use a few words to describe what your thread will be about. LIke "Help with manual shifting RPMs" or something.

More than 90% of the people here will have no experience driving a manual JL, so this will help you concentrate on those that do!

I hate to say this, but you bought the wrong vehicle for being poor. You need a new, upgraded clutch and new differential gears at a minimum. Hopefully it has a quality lift that was well installed and quality wheels and tires.

Honestly, if you really want a Wrangler, sell it and buy a completely stock, unmodified one with low miles. Do nothing to it until you have a better job. Returning yours to stock will still cost you more money than you can spend right now. Your used lift and 35s aren't worth much used, then you still have to buy stock components and a clutch.

Just forget about fifth until you do a gear change.

Yes I need help. But if you think I'm rude because I typed in all caps then you need to rethink life in general. Sorry if i offended you

It’ll be all good.
You’re going to have to drive it differently than you normally would with that gear/tire combo, and you’ll get shitty mileage. Let it wind up into the power band. Don’t try to race anyone.

I just bought all new Ridge Grapplers about a week ago. It's has a mopar lift and fox shocks. I'm about to buy a centerforce clutch. I just want to make sure that's the right move to make is all. If it's not then I need to put that $2200 for the part and install somewhere else.

Can I email you a video of what it's doing? I just don't want a small problem to turn into a big one

Just post it here.

OK

When I hit the clutch to down shift or go into neutral 9 times out of 10 my rpms will almost bottom out then just about 1000 and then settle down. When I start it it will idle about 17000 ish. It will settle down if I give it time or I can pop the throttle and immediately drop to the normal 700.

This is normal behavior on the V6 with manual, and is the result of the ECU keeping engine RPMs higher to prevent unspent fuel from escaping the combustion chambers through the exhaust valves. If you ever hear a "tuned" vehicle that's backfiring on rapid deceleration - that is what's being avoided. Nothing to worry about.

1st to 2nd is ok. 2-3 can be a little weak(in my opinion). 3-4 is really weak and when I'm in 5th it will actually slow down even though I can have it floored. I've been told that it might have to do with the clutch recall.

Here's your real question - and the answer is NO this has nothing to do with the clutch recall. It's due to Jeep fitting the default sport with 3.45 axle ratios, even on the manual transmission, and then someone adding 35" tires on top of that, which makes the final ratio even taller.

I'm poor as hell and I can't spend $1500 just for hopes. This is my daily driver and I dont have anything else.

Ah yes, well advice is free, and I've got plenty of that, as does everyone else on the forum.

My best advice is to return the jeep to stock ride height and stock tire size. That'll get the Jeep driving better, with tires that are better suited to that factory tall axle ratio. If the tires are in good shape, you can probably find someone who's willing to do an even swap with you.

You don't even need to change the suspension, but you'll probably find that you think that the jeep "looks funny" if you put factory size tires back on a Jeep that has a 4" lift. So you'll probably *want* to undo that part also.

Watch for someone selling their "take off" stock springs and shocks. Folks who just spent a lot of money on a lift have a tendency to try and get more than these are worth - which is near zero. A teke-off set of springs and shocks is often simply scrapped. Don't offer more than 100 to take those off someone's hands. Also, don't use springs or shocks from a 4xe, 392, or diesel - those vehicles have radically different weight and their suspension will end up making your jeep sit and ride bad.

Better yet - if the previous before you retained factory wheels with "spacers" - all you need is to remove the spacers and get yourself some factory size tires.

Similarly - if they installed a spacer suspension kit - those spacers can simply be removed to return the vehicle to stock height.

You'll have to do some of your own wrenching on your Jeep here, but that's OK. If you're gonna be poor, it's time you learned some basics.

Yep sounds like gearing not clutch. Sport standard 3.45 gear.
