I have a 99 LX 470 with 117,000 miles. Last week when going down the highway, the car stopped engaging the wheels. When I would push the gas the engine would just rev like it was in neutral. When I put the car in park then back to drive it did it again and would not engage. I changed the setting on the AWD from 4H to 4L and the car engaged and drove fine (obviously at low speeds). I put it back into 4H and it wouldn't engage unless I put the center differential wheel locks on. I am going to take it into the dealership next week. What do you think the problem could be? Bad Transfer Case? Bad Tranny? I wanted to get you guys opinion so I can prepare myself for the diagnosis I don't want to be totally shocked when I take it into the dealership if they slap me with a 5k bill for a new transmission. Thanks for any advice you can give.
