I would like to do some general maintenance on my 2012 Jeep Liberty KK and I am wondering if there is an easy way to determine the drivetrain codes, recommenced fluids and capacities. I have a Suburban that has a placard showing all the original equipment from the factory, so there is no gray area as to what transmission, transfer cases and axles it has. I don't think Jeep has such a placard on the vehicle. I found the following: 2012 Jeep Liberty Sport 4-Spd. Automatic Transmission 3.7L V6 Engine Automatic VLP 42RLE Trans Four Wheel Drive (4WD) / (4X4) Auxiliary Transmission Oil Cooler Command Trac II - Part Time 4WD Dana 30/186MM Front Axle 3.73 Rear Axle Ratio Corporate 8.25 Rear Axle For example, when I go to AllData, it lists TRANSFER CASE FLUID MP1522 1.8 L (1.9 quarts) MP3022 1.9 L (2.0 quarts) How do I know which is applicable? I'd like to change out the transmission fluid and filter (if applicable), transfer case, front and rear axle, etc. Thank you very much for any information that points me in the right direction.
