Steering and Transmission issues

[ShadowsPapa]

- They state our 3-4 gear slipping and park to reverse noise are due to not having the transmission programmed for 35's. I am calling BS on this and we are in disagreement on this right now and they mentioned they will address it once the truck is back up and running.

I'm with you on this, not them. Shift points would be off, yes, that's a given because what it believes is road speed vs. engine speed vs. load isn't adding up, but it won't cause slipping or noises. I'm not just saying it as a random person on the internet with a Jeep and one who has joined the forum - I've done enough transmission work - yes, not THESE transmissions, but it's still about the balance of three things - engine load, engine RPM, road speed. Even the older transmissions had input on those things. Especially road speed and engine load.
Nothing you have mentioned will cause slipping "between gears" or any noise. Seriously - a noise park to reverse? How? No way.

I agree.

Received another call yesterday, the dealer states the regional tech/engineer is stating that the slippage from 3-4 and park-to-reverse noise are caused by me running 35's and the "programming" as well.

Though Regina at Stellantis has said they will reprogram it for me and I would only be responsible for the fuse/aux battery the dealer asked me to pay ~$380 to reprogram it or they can't move forward with diagnosing the problems.

I advised them to get on the same page (Stellantis and JT CDJR) before following up with me.

At this point, it almost seems like they are just squeezing me for cash outside of the warranty.

So you could prove them wrong by using JSCAN, TAZER or AlfaOBD to set the tire size and see if that fixes it (it won't fix anything like park to reverse while it's not running because you could be running 40s and it wouldn't matter shifting out of park into reverse)

They ended up updating the software at no charge after speaking to Stellantis.

However, they now have confirmed they found the park to reverse noise but still cannot figure out where the noise is coming from. They originally removed the new driveshaft and found nothing out of spec. Yesterday they called and stated that the Mopar engineer states that greasing the yoke could fix the P-R issue which sounds more like a bandaid..

Unfortunately, no response after the test drive so I am assuming that didn't fix the problem.. will keep everyone updated so anyone else who has these issues.

Update:
Steering - they state TSB for the steel box is complete and it fixed the steering wandering
3-4th slip - they state they cant find it
P-R noise - they state its the transfer case and it should be delivered tomorrow and completed Friday

Just for another reference point -
my 2020 worked itself into the loose steering, wander. Not a pull, but loose.
On a trip back home from Indiana, my wife drove and as we were leaving the Fort Wayne area, my wife was driving and made a comment I'll never forget "I hope there's no cops back there, they'll think I'm drunk".
that was it, that prompted me to take it to the dealership!
I took it in, and even the service advisor said "yeah, these definitely shouldn't drive like that" after he drove it around their lot. They didn't hesitate and swapped out the original steering gear for the later steel gear.
It seemed ok through the winter, but then got worse as spring approached - in fact, I thought it was a bit worse.
I took it back and let them drive it - and they told me the steering gear was bad and ordered a replacement.
The 2nd replacement resolved it totally.
My 2022 has been fine.

Well to fill everyone in, Joshua Tree CDJR has now had my truck since 3/1 (minus 1 week that we got it back)


They replaced the transfer case on 4/26 and told me the truck is within spec and ready to be picked up after replacing the transfer case, I asked if it is still making the noise, he states they will speak the Mopar Engineer Monday to see if it is within Mopar spec... After talking to the Mopar they agreed it is actually not ready to be picked up and said it was the rear end.

5/8 They called to tell us the rear end did not fix the problem

5/17 they stated they will be replacing the transmission and had to get approved from Mopar Powertrain

5/31 they state the transmission arrived and it would be done on 6/3

6/7 we are told the truck is done and ready to be picked up

6/10 - We requested the invoice before picking up the truck to ensure everything was completed and we weren't being billed for something crazy since the dealer has been playing games since we first started. We received the invoice and no TSB on the steering box was done, dealer states they spoke about it but it didn't need to be replaced (after being approved on 4/10 and being told it was completed 4/18)

We now are waiting for Mopar to follow up to figure out what is going on now..

I honestly don't see anything wrong with those shifts ..I got 94000+and mine has done that for 50,000 miles rev to 3000 drops in 4th and rpms drop and then 5th follows shortly afterwards. They have to Rev up before dropping in next gear . I didn't see rpms pop up back up after it shifted into 4th

The problem wasn’t just that it was jumping up a few hundred RPM when shifting but the fact that every few times it did it you could feel the transmission knockinto gear.

we did get the truck back today and everything transmission wise has been resolved as far as we can tell but we’ve only driven it 40 miles.

The wandering/loose steering is still present but today is day 100 of it being in the shop so we’re just stoked to get it back and will address the steering tsb at a different time..

All in all the noise and shift issues were caused by the transmission but we ended up getting a new transfer case, rear end and driveshaft in addition since the trans was the last thing they replaced.

Sounds to me like you got a new truck practically. Mine has done some funny stuff ever since it was in early 40 thousands. I put the 35's on at 79 thousand I almost got 95,000 on it now. When mine locks in each gear it's rock solid no slip. But the clunk in reverse shoot its done that for 70,000 at least .
Maybe I should have taken mine in long ago. But now I am just thinking with being way way out of warranty that my best bet is just get a used transmission. Or have this one rebuilt. I drive it anywhere from 150-200 miles a day and just keep raking up the miles. Ran like a scalded dog coming home from work not a single hitch . Even floored it once and passed a pilot truck that pulled to the side of the road and ot went from 4th or 5th into 2nd and hunkered down and shot right past .
