Would only let me vote once, but I've had a couple 4xes and no on all of them.

 

2023 JLU Rubicon 4xe. First time pan gasket was replaced. Now a hundred miles or so later, it's leaking again. About to set up a second appointment. Rear of transmission pan - unsure of it if's coming from higher, but appears to be pan gasket and pan bolt area from what I can tell.
So put me down for twice on the same Jeep, second time not yet fixed.

I feel like this has to be due to a batch of warped transmission cases or something

 

Which would be freaky if not almost impossible because, at least before this specific model, they were cast then machined. The casting was machined flat on the bottom to include pan mounting rail, valve body mounting and more.

Plenty of warping can happen post machining, depending on how stress relieving was handled, etc.

 

Just heard on mine - they said it fits the STAR case that everyone else has mentioned. Said they expect the case to be active by Monday.
one other note
Has anyone noticed a slight vibration every now and then while on the freeway going between 55 and 65 in high gear. This could be related. Perhaps causing the failure????

 

I started a thread on this a while ago as well. Just got my Jeep back after getting the transmission replaced and… it’s already leaking again. My best hope is that this is just some excess fluid from the installation or something, but if not, it will be the third time I’ll be bringing it into the shop for the transmission.

 

Is it all over the skid plate cross member, like the photos I sent of mine?

How long did it sit waiting for the transmission?

 

UPDATE - Was suppose to hear something today - Nada - no word......

 

Still no word since 6/28 - just that they are trying to open a STAR case.

 

Updating this string

Recap....

Our 2023 Overland 4Xe went in for the steering shaft recall on 6/5. No issue with the shaft.
At that time it was serviced and it was discovered that the transmission was leaking.
On 6/5 I opened a Jeep Cares Case.
Work was completed and It was returned to us on 6/15.

On 6/28 it was leaking again and was towed to the dealer.
Called Jeep Cares on 6/28 - The case # was extended on 6/28.

I've heard nothing from Jeep Cares so I called them today (7/10).
Now they are telling me my case is in dispute - whatever that means.
Then they said there is nothing they can do as the Jeep is in the BuyBack department.
I never asked for a buyback - I just want the car fixed, in a timely manner.

As far as Stellantis - the left hand does not know what the right hand is doing.

Called the dealer and they told me they are working on getting the transmission leak reported to engineering so that a replacement can be ordered.
They know nothing regarding a buyback.

FYI - If you have an intermittent burning smell you most likely have the 4Xe transmission issue....

 

Day 21 - still no word -

 

I called to make an appointment for our JLU today - can't get it in until August 23rd so won't know a thing for over a month. Takes that long to get in to even have it looked at. I put a piece of cardboard under it today to keep the fluid off the garage floor.

 

I would open a case with Jeep Cares. This transmission leak stuff is out of control.

 

Ah, but Jeep says it's as simple as a pan gasket - not the pan, not a warped transmission housing either I assume.
We'll find out, ours is leaking AGAIN and going back on the 22nd (of August, the fastest they could even look at it)

 

For how many people have had thd gasket replaced and not had it fix the issue, it sure seems like it's more than a gasket problem.

 

I agree. I posted that with a bit of sarcasm in mind, if that's the correct word for it. I was thinking - "yeah, right, sure...."
It does make me believe Jeep is a bit unaware.

 

Does anyone have a specific case number, a STAR case reference or number? I have a feeling I'm going to need to compile all of this info in another month. Here's the current story -

Dropped off our JLU Rubicon 4xe at the dealership yesterday, August 22nd.
Today, the 23rd, they called and said they washed it all off, a thoroughly cleaning job yesterday and drove it - and drove it - and drove it and finally after a long drive getting it hot (not hard when it's 100 degrees outside) they got it to leak again. I noticed the same -
short drives = no leak;
long drive = leak.

They said this time they were going to order a PAN and gasket and replace both pan and gasket.
Last time they replaced only the gasket. They originally said pan but I think he meant to say "pan gasket" not "pan AND gasket".

I told them that either this fixes it - or next time they contact STAR and talk about a new transmission.

They did use every method they could think of to look for cracks, porous casting, obvious issues, and said it's definitely not coming from anything above - the fluid is isolated to the joint between pan and transmission housing.

I tend to agree as when I took my fingers, and even a white paper towel to areas above the pan mounting flange on the case, it came came back dry. Fluid is always only at the flange or below.
So hopefully tomorrow we get it back - fixed. But - not hopeful.

So if it leaks again, I'll be looking for any numbers, examples, STAR cases or whatever, so I can go in armed and get them to not try simple stuff many times hoping like a fisherman that this time, with the same bait in the same lake, they get a fish.

 

They replaced the pan on ours. It still leaked. It has to be some sort of machining issue. They are putting you thru the same process we went thru.
Now 10 weeks later they are planning to finish the transmission replacement this week.

You should open a case with Jeep Cares and demand to be referred to the customer retention department. They should be compensating you for all of this. We are at the point of either accepting compensation or they buy it back.

I'm going to let them do the pan thing and go from there. If it leaks again, I'll contact Jeep customer service (or JeepCares) and start something with them BEFORE contacting the dealership.
If this fixes it, great (but bet it doesn't)
If it leaks again - I'll be contacting Jeep, looking for STAR cases, numbers, specifics and then go into the dealership fore-armed with a bunch of facts and figures.

 

Aug 30th - they are still working on ours...... no word on when we get it back. Not a word from the dealer.

 

Did you ever get it fixed? I dropped mine off before thanksgiving for leak. They said they ordered a new transmission pan and gasket but no ETA of delivery of parts. I looked online and see them available from multiple parts suppliers.

 

When ours was in back in August, they got the pan and gasket literally overnight.
Still didn't fix it so it went back in this month/November and is in the process of having a new transmission installed at this time. That took about a week to get.

 

Ours is getting another transmission. I hate to use the word "new" since often it's a remanufactured unit and not fresh off the boat from Germany. I really wonder how many got "new" vs. what the industry norm often is - remanufactured.
Went in on November 7th for the same leak (after gasket, then pan and gasket) and they said "it's residual from the last time" and I blew a gasket myself.
Took it home late on the 7th and after "discussions" they came and got it on the 8th and it's been there since. They finally contacted STAR (who was hard to get to respond to them) and the regional tech rep and got approval to "release" a transmission for it. Transmission arrived this past Monday and they are currently "working on it".

 

You should be good

 

Thank you for these updates, I’ll come back and check in to give updates on my side

 

Just took our 2021 4xe in for the same transmission leak. Was told they ordered a new transmission pan as the original had a manufacturers defect. Supposed to be in tomorrow and fixed. Will keep this post informed of the results. Only has 6,200 miles on it…

 

what ended up happening with yours?

 

For anyone who has these leaks they all need the transmission replaced. The trans case is defective and is porous allowing fluid to leak directly through the metal.

replacing the gasket does not fix it, and we’ve been getting replacement transmissions in that were literally leaking during storage and transport for the same defect. They’re hit or miss.

Yes, but Jeep insists on other things first. You can't just go in with a leak and say "I want my transmission replaced". Doesn't work that way. They will insist on a gasket, then pan and gasket, and go from there. Some may skip the gasket bit and go right to pan and gasket. They don't want to replace a transmissions worth thousands when there's still a chance of a gasket leak.

 

just found out my 2024 with 10k miles is leaking

 

My 2024 with 320 miles is now leaking. Took back to dealer and they have ordered gasket and pan. Waiting for the parts to come in sometime next week. I was fortunate to get a loaner until then.
