tranny slipping in gear

umm...not a good rebuild.

by the way..don't rebuild these transmissions...they don't like it too much. Put in a remanufactured

To be honest with you and I work for a dealership and I also have a 2000 Jeep Grand Cherokee Laredo 4.0 L When they rebuild a tranny a lot of Mechanics put the Wrong Tranny Fluid in and that causes problems not always dire problems but unless they filled that with Mopar Tranny fluid get it drained and put the right stuff in cause if not the tranny fluid is gonna be to thin and the Galley ways in a trans needs a certain pressure and it can’t build proper pressure if it’s to thin the lifter balls don’t react well to anything else . Also adjust your Kickdown Cable cause that also is a HUGE deal in how your jeep shifts look up Cherokee Ronnie on YouTube he has a great video on how to do it and it’s easy as hell to do you either have a button or a grey clip pop off the clip carefully and press the cable all the way in Go inside your Jeep and press the throttle all the way to the floor then put that little grey clip back in and it should recalibrate the whole thing and if not and needs to shift earlier I think you press in on the cable and put in clip and later you pull it out do this also in small increments to find the perfect sweet spot it could take a few times but adjust it take it for a spin adjust it again if need be but try the first method first of all the way in press gas peddle all the way in inside the Jeep then put clip back in
