Hello, I need some help with troubleshooting. I have a 99 3.0 4x4 162,xxx miles, replaced clutch and slave about a year ago. Only about 2k miles since. While driving, I went to shift from 1st to 2nd coming away from a stop light, shortly after that it locked up,(almost like 4x4 engaged and then let go) it kicked out of gear and has not been able to drive since. No fwd gears or reverse, engine runs just fine, it will go into gear with out clutch peddle, while "in 1st" I can rev engine but it then wants to die around 3k RPM. No fluid loss, good color, res in engine bay is full and clean. No CEL. I need a direction to go in and what to look for. Thanks for any help

 

Sounds to me it's your clutch or tranny thats done. How, I can't tell you, but it sounds like that you've got no clutch system left or that your tranny is NFG, or even both. There are many issues possible. Either way, your tranny has to come out. I doubt it is the master cylinder because then you would be able to move the vehicle because the clutch would always be engaged. Look for issues once the trans is out. Even if you can diagnose the issue without taking the tranny out, its got to come out anyway so may as well start there.

Once you've got it out, I would start with a visual. If everything looks O.K with the clutch and tranny, I would test the slave. Simply connect it to the hydraulic line and pump the clutch, see if it moves in and out. If it does, I would then test the tranny. Try to turn the input shaft when it's in first, second, reverse, whatever, and see if the output spins. If it spins, it may be O.K. If not, there's your problem. I say "may" because it still could have issues which impede it's function.

Needless to say, in summary, this is probably not going to be a cheap repair. I can't say what the issue is, only guess, and my guess is that you'll find the problem upon removal of the tranny.

Hopefully I gave you an idea. This is what I would do, but others may have a better idea. Good luck.
