Good evening scotty,
Earlier this past week you responded to my question regarding my 2019 Jeep Cherokee latitude plus 2.4 problem with the car forcing to downshift after hitting 75 mph and the battery light turning on.
This is a follow up question. I did as you recommended, I took it to autozone to test the battery and alternator and both were fine according to their machines. However, we did find out the jeep had a engine code for P07D9. Which is defined as "Gear shift 8 incorrect ratio." We took it to a mechanic who did confirm it's a problem with the transmission, a sensor of somesort, when in drive with the automatic function the car will force itself to downshift a gear. I was informed that when in "standard mode" where I can control when to time the gear changes it should bypass that problem.
I honestly am not sure what to do as I don't know which sensor it is and it seemed the mechanic didnt know either. He explained that in order to fix said problem the whole transmission would have to be replaced as there hasn't been enough time to fix such a problem on the jeep. I don't know how true that is, I would love to hear your opinion on the matter and how true it is if the 2019 Cherokee hasn't had that many problems where mechanics don't quite know how to diagnose and fix a problem like this without changing the whole transmission.
Thank you very much!
Your transmission is probably wearing out already. You didn't mention your mileage. Stellantis owns Jeep, now. The platform is based on a joint Fiat-Chrysler design, and neither of their transmissions are good; Fiat Chrysler got bought out by Peugeot, and Scotty often refers to them as the 3 Stooges in auto manufacturing.
If you choose to repair the transmission, order a new one, don't rebuild the transmission you already have.
Stellantis also doesn't make Jeep Cherokees anymore, so that should tell you something.
@justin-shepherd geez well thats heartbreaking for sure, my apologies I forgot to add the mileage in as it directly tied into my last post I made. It's roughly now about 149500 miles now. I knew somehow this was gonna end badly, unfortunately I didn't start watching scotty till after I bought the jeep. At that time we had almost 10k in rebates and the deal was there to be made. Now I know well anything relating to jeep, dodge, Chrysler and fiat are abominations. Would you recommend still driving it in its condition? Given the advice the mechanic gave me regarding using the manual shift instead of letting it be on automatic? Me and the missus are trying to come up with some money to either repair or just buy a cash car with a reputable brand.
If is runs in manual mode, you can probably still drive it. Who knows how long it will last.
Toyotas and Hondas are your best bet, generally.

Unfortunately that model appears to be one of the worst of a bad lot.

It's probably not worth putting big money into the thing for a replacement transmission.
@chucktobias thank you man, after reading both links, yea it sucks now knowing the atrocity that is my jeep. It's a kick in the nether regions as I just finished paying it off. It hasn't even been a year that I finally finished paying my loan off back in February
@mr-e About the only thing I can think of would be to take it to a good independent transmission specialist instead of a general mechanic to see if it's repairable without having to spend a fortune to replace the transmission.
