    Ok so this is for those 9 speed owners oht there. Does anyone else get a bad vibration when going 30-40 mph and your car is in either 5th or 6th gear?

    I'm takinh it to the dealership whenever i have time but just wanted to see if anyone else has this going on with their rig.

    The trans case should not be in 6th at 40 mph. The engine is small and do not have the low end torque. That is why the engine vibrates because it is already stressed. If you have a 4.0L then it will pull it at ease, but your engine is 2.4L... definitely stressed out engine. That is a mechanical failure about to happen down the road. IMO, you need to get your gearing reprogramed and module system flushed. I drive the 1.4T manual and I use 3rd gear @ 30-40 MPH.

    Lol sadly this is how my car came from the factory. I am looming into getting the gearing redone though.

    Oh and this is a known issue by chrysler/fiat. They currently have no fix for it.

    Hi Allyus,

    Has your dealership addressed the vibration for you yet?

    This is addressed directly to Kori @ JeepCares... my rene' is now at 3,700 miles. I noticed while driving, I smell some kind of "alcohol-ish" scent whenever I squirt "turn-on" the windshield wiper fluid into my windshield while the car is running and the AC fan is "on" and all the windows are shut close. Is that a concern that I should take care asap? I feel like some kind of toxic chemical that I am inhaling will effect my health in the long run.

    Technically no. I brought it to one dealership that blamed the vibration on my new tires being out of alignment so i redid that for the third time and it still vibrates. The second dealership i brought it to told me it's a known issue that automatic transmissions do this due to the fluids moving around and shit...it made sense when he explained it to me and also smelled like bull shit.

    If you're asking if someone has physically looked at the transmission then no. The dealerships keep touching shit on my car that i don't ask them to and then blame it on what they touched rather than fix the issue i explained.

    I work on aircraft for the united states navy. So when it comes to quality assurance, that's high on my list and so far chrysler/fiat have done nothing but waste my time and gas.

    I would say yes, if you're experiencing a toxic smell, and it's happening regularly, take it in to the dealership and demonstrate it for them. Let me know if you need any assistance.

    I do apologize that your time has been wasted and the vibration not addressed satisfactorily--if you are willing to visit a dealership again to have this addressed, I would be more than happy to step in and make sure they are understanding your concerns correctly, and involved our corporate techs if needed.

    Lol ive been to two dealerships in regards to all my problems and they continue to blame whatever problem i have on any aftermarket parts on my car which are unrelated. Sure bigger tires may fuck up the transmission but not in the first week of them being installed and only in low speeds? And the light issue i have (another topic on this forum) was also blamed on the led lights however after putting oem ones back in they still cause the error.

    Go ahead and send me your VIN when you have a chance (in a PM) and I'll connect with you.

    Hi Kori! I was hoping you could give me some insight here since my issue is similar to the person that created this thread. I've noticed that my Renegade ('16 Trailhawk) likes to get into high gears even at low speeds in automatic and seems to favor RPM ranges that seem very low. I've seen it as high as 8th gear between 45-50mph (Checking it by tapping it over into manual shift mode), and I've seen it running in 9th at around 60mph. This is my first experience with the 9 speed automatic transmission, but it definitely strikes me as strange. Similar to the user you were helping in this thread, I've also felt unusual vibrations when accelerating when the engine seems to be in too high of a gear. I've heard around the forums (It was also mentioned in this thread) that this is a "known issue" and that Jeep is working on a fix, and I was wondering if you had any information that could confirm or deny that, and if it is known to be a problem, is there any timeframe on when we might see an update to fix it pushed to the dealerships?

    I'm concerned that this could be putting undue stress on my engine and could cause premature wear. Is that a justified concern, or is it not a big deal? It does seem to have a negative affect on my MPG. I've noticed that it seems to help when I keep it out of 8th/9th gear until my speed and RPM require me to go that high.

    Also, is there any way to be notified of software updates for my vehicle automatically? Or is that only possible by actually going to the dealership occasionally to have them check? I'm always concerned that I'm going to miss an important update.

    That's interesting your petrol TH is completely opposite to my diesel TH that does not like to change up until 3000rpm. Its almost like someone put the petrol calibration in the diesel and the diesel in the petrol. You don't think some engineer issued the wrong suffix to the software.

    I am sure that your vibration concern will add "wear and tear" into your engine. From transmission to your transfer case, up into your camshaft to the pistons.

    All of the sliding metal "spinning" and "rotating" parts and sensitive components of an engine has to be precisely synchronized.. bearings, hydraulic pumps or what not, they are all precisely machined down to thousands of an inch or better. Ask yourself, what do you think is happening inside there with hundreds of moving and sliding components at 3000 revolution per minute (that is 180,000 rotations per hour of use my friend) fatigue occurs when some parts starts to rattle caused by vibrations. Imagine this: metal is just hardened compressed tiny granules of sand-like (under microscope) compacted and bonded together. Some "granules" will give and break down the road when continuous load stress is applied.. If or when there is already a clunking and/or ticking noise, it will be a bit too late then... and what if your warranty is over when that happens?

    Hey Numlok,

    I check with my techs here, and they responded that there could be multiple reasons for the concerns you’re experiencing, and suggested having the dealership go over everything, and then escalating to them if needed. Sorry that’s not as much of an answer as I was hoping for, but let me know if I can help get anything set up for you.

    Additionally, with TSBs, they are listed internally, so there’s not really any way to check for them unless you go to the dealership or ask us.

    From what I have heard from some contacts at ZF. The dealer can clear and reset the adaptions in the box. It's a long process and not all dealers have the techs that can perform this. You also need long straight level roads and steady state throttle so the internal fluid pressure for each gear can be adapted without changes in engine torque effecting it etc. Its about a 2 hour process. They can do a quick learn but most people report no improvement with that.

    TSB 21-012-16 for the diesel. There is similar one for the petrol.
