91 explorer tranny problem

Hi everyone I have a problem with my 91 explorer tranny, I replaced the front seal added fluid went though the gears everthing went fine felt gears gone in reverse and forward drove it out the garage onto the street parked it. I went back to test drive it,no go no gears whats so ever like its stuck in neutral I took shift cable off and put tranny in gear by hand and still nothing. So if any suggestion I would appreciate any response. :confused:

When I have that problem with my 97, I found a bolt on the floor, I came from the under the dash it held the link to the shifter. Unfortunately it happened while I was driving so it was stuck in drive really sucked to park.
