Manual transmission not transmitting!

Please send me some rust, I can't remember what it looks like.

If the clutch is bad you would hear grinding of gears when you try to put it in gear and likely notice the distinct smell of a burning clutch.

Just wondering--why did you put it in neutral when descending rather than just push the clutch in ?

Bahaha.

OK seriously, given the economics I might consider putting an np203 in this hulk if I get my other car running for daily duty. I think I could do better than 1500, and have less failure. They are very heavy though.

I have to slow down and cone to a stop right out of the parking structure. There at speed bumps right before. Its a big decline so I just coast all the way down. People walk all over there so you have to go slow for a while. Gravity does all the work.

The driver's side rear axle shaft had come so far out of the differential that the transfer case was putting all output to that wheel. This is how it is supposed to work.

Hi lo_jack,

Was the drive shaft and transfer case the problem? I ask because your symptoms are exactly what I experienced the other day. I have an 05 X5 and the thing will not move forward or reverse. I drove to work one morning and everything was fine. I got into my X5 later in the afternoon to go to lunch and the damn thing would barley move. It would rock forward sometimes when I manipulated the clutch, but then would feel like it was in neutral with the engine rpm's going up but the car not moving. My X5 has 160,000 miles on it, and I replaced the clutch and flywheel in April of this year. There were no warning signs that a failure of any sort was imminent. Not popping, grinding or anything. It has only about 2000 miles on it since the clutch job.

No, the transfer case was not my problem.

The way this AWD transfer case is designed (without a locakble differential inside it) AND open (not limited slip or locked) final drive units, power from the transmission will be applied to the axle that spins the easiest, or has the least perceived traction. That is exactly not the axle you actually want to spin, as it happens.

That means when my driver rear axle shaft popped out of the differential, the driveline only wanted to spin that axle, making the vehicle have zero forward velocity.

I would check to make sure all of your axles are in all the way in the differentials, then start to see if the transfer case output has failed.

My mechanic put it on the lift with me in the drivers seat this weekend, and we did some tests. Miraculously the X5 started working fine again when we set it back on the ground. He told me to drive it to see if it would do it again, and sure enough it stopped working. I drove it to work this morning and it was fine. Got in to go to lunch and it was not working. It worked fine all day Sunday and half of Saturday.

No idea. Was it a body lift or a a wheel lift (that you drive on)? If the former, you unloaded and reloaded the suspension, and that might have changed something.

It was a body lift.
