Hey guys, drove my truck to work this morning (01.5 CTD 2500 6 spd NV5600) and backed it into my normal parking place, put it in neutral let clutch out and set parking brake, a few sec later i felt a bit of a lurch, heard a bang or something and the truck shut itself off.

Come out of work tonight, start truck and let my foot off the clutch, truck bogged down and died in NEUTRAL! Restarted it and put it in 1st, didnt move and bogged down like i was against a brick wall trying to drive through it. Every gear including Neutral will not move truck, only bogs down until it dies or i put the clutch back in. Truck WILL roll when in neutral with foot brake off. when it rolls and i let clutch out it stops itself then begins to bog down until i depress clutch.

what in the H#LL is going on here, its obviously either the clutch or the trans, but beyond that in completely clueless and we have a very limited amount of places here to look at it.



Any more questions i can answer about this let me know and i will answer. Also, if you have an idea whats going on let me know!

You can rule out clutch. I would lean to somehow it has locked itself into 2 gears at once.

Never heard of such a thing happening on it's own ( no stick input ), but that's the best I have right now.

sounds like something came loose in the 6spd and has jammed the gears. bad part is there is no top to remove to see only the shifter. I would pull the PTO cover and fish with a magnet and see if you come up with something.I have seen gear teeth brake off in the 6spds ,that might be whats doing it. let us know what you find.

If it is running normally with the clutch depressed I would rule that out for now.

It is something in the trans or with the parking brakes.

it cant be the parking brake because it killed itself in neutral and the truck rolls. it also would allow clutch o be engaged with truck running which it does not do

I too am leaning towards something broken in the trans and causing severe binding.

Try draining the fluid and looking in the PTO covers.

My 01 just did the same thing pulled the trans apart and had a syncronizer shreded. Wouldn't think one synchro would do that.

update again........truck is still moving under its power in N but 6th gear will NOT go in. so im thinking its stuck in 5th or 6th, what rail is the 6/R gear on? is it the same rail?
