Jolting at 25mph immediately conjured up an image of an inexperienced driver whom has selected a gear that is too high for the speed they are doing.

I know my Jeep 4x4 Longitude (manual, diesel) can do 25mph in 4th gear extremely comfortably. 5th gear and it will get a little tempremental and start to ever so slightly judder but if I merely accelerate a little to 30mph I can alleviate the juddering and at 35mph to 40mph I can drop into 6th gear.

Now this is important I have my Jeep chipped however any modern car, never mind a Jeep should be able to sit at 30mph in 4th gear without jolting.

Are you therefore driving in the appropriate gear at the appropriate moment depending upon the terrain you on whilst taking into consideration the incline or decline that you are traversing?

I have noticed on my 2022 Renegade 1.3t is while accelerating from 4th gear into 5th gear is that when release the throttle right before its shift point the transmission jolts into the next gear which is accompanied by an audible thump. It seems like normal operation to me, so far its been a sporty and exciting car.. I just have questions on oil viscosity. My 1.3 does sound noisy sometimes, but it is not so much ticking as it is the clicking sound of the components within the engine functioning normally. Could this be a result of OW-30? I have only used regular fuel (87). Could this also be a result of using low grade fuel?

I had problem, dealer didn't know what to do in 2020 for my 2017 trahawk so he changed my engine without initial approval as I have a lifetime warranty, my mileage still not same and the violent kicking is starting again (soft kicking around March, april). Not again. : (

Seems like it could be a lack luster attempt on FCA's coding of these transmissions, but, I think when you involve the 4x4 mode along with all the different ride modes on the Renegade it can become very hard, nearly impossible, to ensure that no issues will arise--even with proper maintenance and preventative care. This can become a strain on the modules ability to adapt, leading to quirky instances of harsh shifting and jolting.

This is my theory as most fixes are not mechanically related to the transmission, therefore, they are serviced via software flashes.
