prolly a really stupid suggestion but is the prop and diff ok? like i presume prop isnt turning, (speedo not going up) worth a look!

Mine a BW65 i think, could be 35, can't remember now....
Gonna investigate later after i've hosed it down a bit!!

Hi Will- it reverses fine so i'm assuming everythin south of the trans is ok

hey paul does it drive in lockup 1 position, if it does the one way clutch in the centre support has flipped out, other than that i would think that frantic use off the shifter between drive and reverse has made the foreward clutch give up, its a while since i done a 35/65 sat tryin to think off any thin else for ya

Ta mate, you're in the right area i think...

Dropped the box out last night, that familiar smell of burnt cork tainting the fluid as it drained.
The final comfirmation that the trans is fried is in powder form, clinging to the little magnet in the sump

Overrunning clutch might have popped out? Burnt clutches wouldn't loose you all forward motion completely would it? It would just slip yes?

Just trying to get the mechanics of it sorted out in my head.

yes you would lose all foreward drive the clutches wear so bad that the piston cannot travel far enough to clamp the clutch on, they will often overtravel and the piston comes out off its bore and cocks over and this useually locks the clutch on and wont release goes foreward in every gear position cept reverse and in that it dont go nowhere

Sounds right- it's pretty much why i had it rebuilt 1st time a coupla years ago but that was due to years of wear, neglect and water contamination. This time it all went wrong in a matter of seconds!!
I've spoken to Steve at Chester Auto Transmissions ( he rebuilt it last time ) and he said same as you Cannonball.
Seems to be a common problem with these boxes cos so many of the 4x4 boys use 'em and abuse 'em!

Interesting point that last bit, as these boxes were considered marginal on higher peerformance Rover 3500s and Jag XJs, so lord knows what they suffer in a powerful 4x4.

Thanks for explaining that Dunc!
