Hi I just swaped my transmission for the later R380 and transfer. Was really worthwhile the annoying "clunk" when chaning gear has now gone, and the gearbox shifts way better. I allways suspected the clunk was the output shaft, so to check I jsut seperated the gearbox and transfer. Regards this I have a few questions I just seperated the two by un doing the mating bolts, it then came apart with reletive ease. I noticed however that the input splines had thread on the end. Is this suposed to have a nut on it (mine did not). Could definately see 50% wear on GB splines, can I expect equal wear on the input splines on the transfer? Wondering wheather its worth using as a spare as it shifted very well. Cheers Jim
 
only lt77s have threads ,and it doesnt have nut its used in stripping and rebuilding gear box if main shaft splines are worn input gear will be equally worn too ,a worn spline will wear a good spline out quite quickly

I got rid of my "clunk" the cheap-skate way on my R380.
Having an early 300 the input gear in the TB had less spline than the later gears and no oil drilling.
I had the gear swapped for a new later version one so that its extra spline length contacted the un-used portion of the GB out-put shaft splines.
Clunk fixed for the last 20k.

some people may be lucky ,but i have seen a lot of recon boxes which have had new main shafts ,worn out in less than a year because new input gear wasnt fitted with the gear box
