Range Rover Classic potential buyer question

[HorribleHarry]

Hello all, I have been thinking about buying a RRC the last couple of years, and have had a nagging question. I want to know if there are any disadvantages to the 1989 and later BW 13-61-004 transfer cases? My goal is to do a fair bit of trail type off roading, not rock climbing stuff but more or less hardcore trail driving. Am I correct in assuming the later transfer cases DO have a lock up feature at some time? I know the LT230T has a mechanical lock available to it... does the Borg-Warner 13-61-004 actually lock too?

I guess what I'm asking is, Is the later Borg Warner case as good OFF ROAD as the LT230T?
or is there something offered in the later versions of the classic that outweigh the capability of the t case?
OR... should I get a Discovery 1???

Thank you for looking,
Harry

The BW cases actually work very well and lock up by means of a viscous clutch. Sometimes they fail by the fluid getting burnt up and then remain locked all the time. Get a post ABS truck for parts simplicity, the '89 had 10 spline axles and different CVs.

Ok so it's a viscous clutch, like the one in my syncro... which means it dosen't REALLY lock up! (all the way) I was thinking they put something in there to make it a true locker. Nonetheless they do look like they do a good job.

It is a true lockup. It's actually quite a nice system. Definitely worth having the 3.9 as well!

Of course some people will always like having a manual lock up, but the BW is very, very close, if not equal, to it.
