Question about 2002 Jeep Liberty

02 Jeep Liberty check engine light and trans. revving

The check engine light came on and then all the sudden the transmission started revving instead of kicking into gear. Only does it when I am in alot of stop and start traffic. Auto Zone said it was a Oxygen senor problem. Any comments. Please help as I am on a new base and not sure of where to take the Jeep.

The switch is on the outside of the transmission case. See a photo of it below. It may have a short lead on it or the harness plugs directly in.

I want to change a 3.7 motor off of 2004 jeep Liberty 2wd in order to fit my 2002 jeep liberty 4wd?


engine swaps are complex as is mixing engines to wrong transmissions.
so both are 3.7L, is that it?
you never said what exacty didnt fit.
the flex plate to TC
or TC to A/T pump side mismatch.
????????
if its the flex then get the correct flex plate.
or call jeep parts? ask them for the right parts
the side of the trans has the trans part number
my guess is all you need is the correct flex plate for engine to TC.

How do I check Transmission Fluid on my 2007 Jeep Liberty


Jeep decided that there is no need to check the trans fluid, the trans is is sealed unit. You have a tube for the trans fluid, but it has a factory cap and no dip stick. A special tool is needed to check the fluid level.

Have a 2005 liberty 3.7 trying to install into a 2002 liberty but motor will not bolt up to trans. due to somthing on end of crank hitting converter? fixable problem?


If the engine was for a manual,there will be a pilot shaft bushing there.Not sure if removing it will help or not,the crank maybe different,if this is a used engine,you may have to get the converter from the other vehicle,if it was a automatic also.

2002 Jeep Liberty Radiator/trans cooler


If you want to install another cooler, you will have to put it in-line either bofre or after the radiator. I have a liberty as well, and have done much towing, and have never had the need for an additional trans cooler.
