2002 2.7crd grand cherokee wont change gear. « on: November 19, 2006, 13:45:30 ». Hi all, my Jeep has just stopped changing gear, it will go into reverse and forward gear but will not change upwards; max speed of 40mph. The fault light that looks like a gearbox has also come on. There is no dipstick to check the oil for some reason.
The black plug pushes / pulls out 1 or 2 mm but ive pulled, twisted, squeezed for an hour - but I cant get it off / open - and I dont want to break it.. Ive searched for vids / info but no one seems to specifically say how it comes off. The FSM just says "Press locking ring at bleeder valve in direction of arrow and pull off seal."
