Sounds like the torque converter is packing up...worth checking fluid levels though and cleaning the gear selector switch and see if that helps...

I'd say the AR25 is kanckered, and its not surprising.  TC's rarely fail, and when they do, you'll know!

Try to replace with a AR35 if possible, though you'll have to use the TC and bellhousing from your box (TD TC and bellhousing is unique)
