First a disclaimer, I know very little about transfer cases. Last week the weather here was pretty bad so I had my '80 fj40 in 4hi to get to and from work (about 2 miles round trip). Everything was running great with the exception of a minor short in the ignition harness plug that's fixed with a little wiggling when it's acting up. I left town for the weekend and my wife was driving the truck and when I get back, it's no longer accelerating. Top speed is about 20 mph and it takes about 1/4 mile to get there. It feels like the transfer case is out of gear, but I know it's "in" according to the shifter. I've got it back in 2 and unlocked and it's ridiculously sluggish. Any ideas?
