2013 Torque Converter issues?

Well my jeep has been shifting weird for a while now. I finally took it to the dealer to see what is up. They told me they could not reproduce the issue.

let me try and explain this. When I am going from 1st to second, second to third the rpms hit about 3k and fall back or sway to about 2500 ( not shifting ) then climbs again back to 3k then shifts gears. Or it will seems to freeze at around 2800 rpms for a second or two while the MPH climbs then the RPM's will climb again.

Theres no consitant climbing of rpms and shift points. I have a stock jeep with Rubi take offs that were calibrated for. I cleared all calibrations prior to taking it to the dealer and still noticed the issues. Dealer says there were no error codes in my system. Any ideas?

Other than the tranny, this is my third Jeep ( two TJ's prior ) I enjoy it.

Does the engine SOUND like the revs are wandering around? It may be a problem with the tach.

My '13 attempts to shift to 2nd but just revs up. After a few seconds 2nd will 'catch' and the rpms will drop because it's finally in gear.

Other gears shift fine.

2nd shift fine when accelerating around a sharp corner oddly enough.

Mine does it, only when I'm going up an incline I get the feeling it is shifting funny. It's almost like the passing gear downshifts but does not want to go to the next gear and winds out more then I'm used to. I get it when I'm slowing down, mostly on an incline, it wants to stay in its lowest gear and wanders through the shifting points. I usually manually shift when it does that.

The engine rpms sway along with the engine. Almost like it wants to shift but sways back 400 rpms then increases back to its original rpms prior and then finally shifts. It does this with a constant throttle. I even tried it with a heavier foot into it and if it didnt sway in rpms it froze around 3000 rpms for a second then increased to 3500 and shifted. It is extremely annoying.

If i am giving the engine constant increasing throttle I dont want it forgetting what its suppose to be achieving. I am new to drive by wire in a wrangler. If that is what is causing my problem then after 5 months its got to go.

Im going to head in next week and drive an exact model off the lotand see how it runs. If i dont notice the same problems i am encountering, I will take the service tech with me on a drive in mine.

Its easy for them to say they could not reproduce the problem with me not in the passenger seat. Starting to feel like six degrees of seperation with the links that were posted above.

I wish these three common posts could at least all be in the same section. I hope this 'shift' of posts doesn't take long or hamper us from finding helpful posts.

Yea, I agree. Not sure how to get the other two links wrapped into mine or vise versa. Sounds like were kinda related in some way.

The engine speed,sound seems to match the sways and freezes in rpms. Happened again on the way to work this morning. I was giving it constant throttle and around 2800 rpms it froze for about 2 seconds then continued to climb to 3k and shift. If i let my foot off the gas or let up on pressing the pedal i could understand the lull. Could this be the drive by wire system??

Kinda makes driving the jeep not enjoyable. Always feel like I am doing damage to it or something.

So are you guys stock? I've described my transmission issue already, but I must point out I'm running 285/70/17 with an adjustment made with a flashcal.

So are you guys stock?

Sounds like the TC is locking up (rpm's drop by 400) then unlocks again (rpm's increase) before the trans upshifts. Shouldn't be happening with constant throttle input.

I have the exact same issue. Took it in and they said it's normal. I have never experienced this on any other auto trans. I think I'll take it back again until they do something about it.

I have a feeling it is the how the TC is programmed to lock and unlock and is probably normal. A Shipmate of mine has a 12 JK Sahara and I was driving it the other day and noticed what I'll call a weird shifting pattern. It would shift into the next highest gear, and then the rpms would slowly "slide" down, and gradually rise again as I slowly accelerated, and then shift to the next gear. This was driving it like an old lady to get it to do this. OD was weird as the TC would unlock to increase speed and then lock up again and the rpms would "slide" back down. I know it wasn't downshifting because I wasn't mashing the pedal.

Still, I got all sorts of answers on here that it's normal, torque lock-up, etc...well, my new transmission (in at ~2500mi) has been fine ever since, without the "stutter". Now at ~8500 miles. I'd say keep pressuring them.

Ok, well sounds like some more situations have come about. If you had your tranny replaced and it no longer stutters, freezes or sways in rpms then theres definately a problem. The mention of possible TC locking up sounds exactly what I am experiencing.

Our 2013 JKU Torque converter was replaced around 7k miles.

It had been shifting weird and while punching it going up a hill, it kind of stalled a bit and then the check engine light came on.

The dealer ended up replacing the torque converter.

The code was P0741.

Mine does the same thing (2012 With 12000 miles). I had the P0741 cel come on 4 times now. Last time they replaced the valve body, next week they are replacing the torque converter.

Funny thing is I havent thrown any codes. Let me know if the problem is resolved with the new converter. Ive been holding out on mods until I can get a definitive answer if this issue is normal per factory programming.

My 2013 JKU with 24k miles is being worked on as of last Friday for this issue. I was having issues accelerating and it went into limp home mode. I turned the engine on and off and it cleared limp home mode for a few seconds... until the check engine light came on and it started again. I never got the number of the code from the service center, but it is for some solenoid.

They replaced the valve body first, and now I am waiting on the torque converter to come in. As far as it looks, this is an issue that exists with these transmissions. I'm trying to get more information from them about what may have been the cause. I worry that it will happen again with the replacement parts when it is no longer covered under warranty.

Prior to this happening, I will say that there were times where I experienced a "lag" when accelerating. It would make me nervous to change lanes during rush hour because sometimes I would speed up just fine, and other times I half expected people coming up the faster moving lanes to slam into me. I don't know if this is a result of issue with the torque converter, or if this is "as expected" for the Jeep.

I'm posting here mostly so that when I get my vehicle back (fingers-crossed for tomorrow) I remember this thread and I can update with any differences I might experience.
