ok i have a co worker that has an 89 bronco and it wont get out of 4L ok i will tell you what he ws doing one day. Ok so he was hauling a pipe across his lawn so he can out it in his big *** garage, and he has a hole in his yard and he sunk down into it and he was trying to get out of the hole, and he told me that he heard a very slight clink and now it wont come out of 4L. I mean he tryed everything to get it out of 4L, so i am trying to help him out by trying to see why it wont get out of 4L, so any suggestions i can tell him, so he could get it fixed
