I might come to a stop sign and it will go back in to 4 high but then later I look down and I can feel that I'm only in Front wheel drive. I am getting much better MPG because I'm only using the front however I actually need 4x4. My local mechanic is lost, and no one seems to know. IS there a sensor or wire that may be loose or bad?
1. It's a 5.2L V8
2. Your T-Case is most likely a 249
The 249 is a Full-Time 4WD Transfer Case. It operates in 2WD (Rear Wheel) until it senses slipping in the tires and then transfers power to the slipping wheels (Front Wheels) And that's the simplified explanation.
I don't believe it would have the ability to operate in Front Wheel Drive. I can't fathom how that would work -.-
You need to take this thing to a Shop that works on Transmissions, Transfer Cases, and Drivetrain if you really think it's using Front Wheel Drive....Like DaemonForce said, that will most likely turn into No Wheel Drive. Lol. But I doubt it's actually in FWD.
