About a year ago I purchased a 96 f150 with a e4od transmission. From the beginning the gear selector was a little loose and the detents were off by about a half of a letter, but wasn't a big deal. However, a few weeks ago the selector got even looser, so i decided to fix it. I noticed that there were some bolts loose under the dash where the cable was connected to. I tighted them up and the detents were perfect. However, now the drive detent doesn't work, the transmission just slips. 2 and 1 work fine. I recently loosened the bolts back up and drive works again, however the detents are loose and I am back to the original problem. What is going on?
