I have a 97 Expedition 5.4 Xlt 4X4. E40D Trany / 4406 Borg Transfer Case. A Couple months back i replaced my tranny with a junkyard certified working unit. Everything has been working great until a couple days ago i was on the highway and lost all gears. I coasted off the ramp and pulled over with no drive. I turned the car off then back on and went through all the gears including awd & 4 high & 4 low and reverse. It felt like it was shifting but no motion. When i went to shift back to park there was a grinding noise. (No dash light warnings or computer fault codes from the obd 2.) I then turned the truck off for little while and then started it again. Still no drive until i activated 4 wheel low, then i felt motion. I was able to move the truck slowly off the highway. I then put the truck into 2 wheel high and it would not go above 20 mph. I had the truck towed home. Today i checked it out more. Tested all the fuses and made sure that nothing came unplugged on the tranny. Changed the transfer case motor just because. That's about all that i have tested. Only other thing i did was disconnected the battery for a couple hours and still not going above 20 mph and won't shift from there? Any suggestions would be a blessing. I did notice also that sometimes when i go to start the truck that i have to move the shifter into park more to get it to start and only 1 or 2 times the truck would not shift out of park.
