I am not sure I know whats wrong with it. What did they determine was the noise? You know it may just be that one of the torque convertor bolts backed aut and is hiting something in the bellhousing area, have seen that a few times ,especially after work was done involving removing the bolts.
On a difficulty level of 1 to 10 on nissan transmissions, the D21 series 4x4 trans is probably a 9. Alot of stuff needs to be removed including the torsion barsmake sure you measure the length of the threaded section of the adjusters to reset it back to its original ride height when going back together.Before you undue any part of the torsion bar you need to release the tension on the rods by loosening the adjuster you measure. [DO NOT dissasemble the torsion bars], be sure to leave the bars in thier holders, on the front undue the 2 14mm nuts and one larger nut to releast the torsion bar from the lower control arm.On th back remove the 4 17mm bolts holding the torsion bar cross memeber to the frame. The starter comes out from the front of the crossmember, you need to unbolt the idler arm from the frame and let the steering linkage hang inorder to pull the starter all the way out at that point you can remove the golt bracket that was around the starter and gain access to the torque convertor bolts. Before even going under the car there is a loom of wires coming up by your transmission dipstick on the passenger side. release the loom from the dipstick tube and anywhere else up top and disconnect the 4 or 5 connectors on the loom along the passenger fender well in the engien compartment, then push the whole group of connectors down under the car.
Thise are a couple of the more important things I can think of at the moment ,if I can remember anything else I will let you know. Also DONT do this alone you have to have a second person help you. As you now that trans is very very heavy.
