Almost everytime when I Drive my WJ it struggles to shift into 3rd. Sometimes the rpms will go all the way to 3000 before it shifts. But sometimes it shifts fine. It's 2wd btw. I tried to get ignition codes bit it only says done. Someone plz help me.

 

When was the last trans oil service?

 

Probably never. I've owned it for nearly 3 years and have never changed it nor the filter.

 

I've added no slip fluid it before buts it.

 

I would start with having the Transmission serviced, this will give you a good baseline.

 

I serviced the trans today and now it shift wonderfully haha. So far so good.
