My local dealer has an 08 Cherokee Laredo 4WD I am interested in. 47,600 miles 3.7L Gasoline engine full time 4wd Can anyone tell me their experiences with these? I'm most interested in learning about the engine and transmission. Tell me the good, bad,&/or ugly about them please. How hard is it to change the trans fluid myself?? I saw the oil filter right up front and easy to get to thank goodness. Thanks for any help you can offer.
