We recently bought a 1995 4runner 4x4 with a blown 3.0 engine. After rebuilding, our 4runner ran great, and for 2 weeks it was our daily driver. 2 days ago we drove it to work, and then again to grab lunch. It ran perfect. Went to leave work and I didn't have any gears in 2H or 4H, only was able to move it in 4L. Pulled it in our shop, tranny fluid looks good and was full. Husband tore apart the transfer case and doesn't see anything bad, except just a small amount of scaring on direct drum. Any help appreciated!
