SOURCE: can i use a transmition from 1998 grand cherokee laredo 4wd to a jeep laredo 1998 4.0 4wd. will work same trnsmition?

Hi Jose, I've never tried but if you go visit a breakers yard and compare the physical dimensions of both boxes and they match up, there is no reason why they should not. Most manufactures use the same units in a variety of models and if you've found a similar vehicle with identical uses the parts are most likely interchangeable. Regards John

If you're saying that you already had the troublesome crank sensor replaced then maybe your electrical connections to the sensor is bad, somewhere, along the way to the ecu.
