    2011 KK Liberty - Cold Weather - not upshifting error TCM P0882

    Today, one day later, two test drives yielded no limp mode, no P0882 code. Which makes diagnosing the problem problematical.

    2011 KK Liberty - Cold Weather - not upshifting error TCM P0882

    Update: as I said, the TIPM's plug-in relay on top tested ok (and I also swapped it with another relay). There is no internal micro-relay driving the on-top relay, the driver is solid state. The on-top fuse is also good. I removed and disassembled the TIPM - found nothing obvious. After...

    Lift struts for the hood

    Well - the kit includes brackets - the KK hood has no attachment points for hood struts.

    2011 KK Liberty - Cold Weather - not upshifting error TCM P0882

    The saga continues. Most recently it did the same thing, put itslef into Limp Mode first thing in the morning after being fine prior and 60+ deg F overnight (i.e., toasty) - without turning oit off I dorve it to the dealer at less than 60 mph I had an appointment) and turned it off in their...

    Lift struts for the hood

    The hood on my 2011 Libby is too heavy, so I just ordered this: https://warriorproducts.com/jeep-liberty-hoodlift-kit.html Wish me luck with it.

    Need help with traction control light

    Just ignore it if the car is driving ok. IF in doubt, go out to an empty area and try a panic stop. If it stops in a straight line- you are ok

    Half ass maintainance

    I have never had an AC evaporator car fail in my auto, since 1970s. Cost me about $1300 to get heater core replaced in my 2008 Liberty.

    MP1522 Transfer Case Fill Volume

    6/27/2023: I emptied almost 2 qts out of the 2011 Jeep’s MP1522 transfer case at around 89k miles – likely the original amount filled was 2 qt. So, for a refill use 2 Qts, no NOT fill until the fill port is overflowing.

    KK Liberty Lift - Shock preference

    I used Rough Country, it worked fine on my 2011 Libby. Loaded front coil-overs, and easy rear springs and shocks. 2.5" lift kit part #68731 from 4WP.com FYI - I did the Jeepin By AL kit on my 2008 Libby. The loaded coil overs from Rough Country were so much easier to install.

    Transmission Skid Plate DIY

    The OEM skid plates were not expensive, as best I can remember. I bought a MOPAR skid plate for the transfer case on my 2008 Liberty. The price was no big deal.

    2011 KK Liberty - Cold Weather - not upshifting error TCM P0882

    According to the Youtube reviews, its only good for about 30 MHz (not the claimed 100 MHz). Quality seems fine - there is not much to it, a case, a display, a mainboard, battery, and three probes, and a decent Users Manual. I paid $169 on Amazon, I could have got it for less on ebay. Its user...

    2011 KK Liberty - Cold Weather - not upshifting error TCM P0882

    well, I bought a cheap 2-channel FNIRSI 1013D oscilloscope from Amazon, I bought this solely to diagnose code P0882: low voltage between TIPM and PCM on my Jeep Liberty. Being able to see the request voltage and the output voltage on the same screen at the same time will be most enlightening...

    2011 KK Liberty - Cold Weather - not upshifting error TCM P0882

    So we did another camping trip a week later - out to Utah and back, towing our camper. The problem occurred twice, only after the first start of the day, typically after sitting overnight leading to a cold morning. But not always very cold. The same fix worked in both cases. It sometimes sets...

    What did you do to your jeep today?

    2011 KK Liberty - Cold Weather - not upshifting error TCM P0882

    The problem is electrical - not related to ****** fluid level. Else the battery disconnect trick would not have worked on those cold cold mornings. Now back in warm California, the problem is not occurring (but still needs finding and fixing).

    2011 KK Liberty - Cold Weather - not upshifting error TCM P0882

    On our recent trip to Idaho towing a small camper, everything was fine, including crossing the Sierra Nevadas, until the 3rd morning. It was cooold – a bit above freezing. The ****** would not shift above 2nd gear. The temporary fix was to disconnect the battery – this fix lasted all day. Next...

    Rear Height - OEM Lift with Tow Package

    well, its a moot point, the 2011 now has a Rough Country lift on it, installed by me, and the final heights at wheel wells are similar to the 2008 lifted Jeep (front locations are higher on the 2011). The Rough Country front coil-over struts just barely fit.
