Thread: Roamerdrive into 130 converted to 4bd1/t running an r380

Sent the manufacturer an email. As I'm running a disco transfer case I cant fit one. I need to revert back to a defender one or a Disco 2 transfer case. Baz

Hi Barry

If the transfer case is from a Discovery II we can provide an
overdrive. If the transfer case is from a discovery1 you are out of
luck. Ray

So asking for pardon in advance, and at the risk of a significant highjack, anyone able to explain the fundamental differences between D1 and D2 transfer cases?

I have a vested interest in the answer for my RRC which has a Borge Warner Viscous Coupling that I want to change to a Transfer Case, but will be mating to a 4HP24 and D2 TD5, not a LR V8!

Hi Gavin, for fear of perpetuating the hijack - and providing useless information - I replaced my Viscous Coupling with a D1 transfer case in the LSE. Mated up to the existing ZF. It was from a 1998 D1 I think. Had the V8 in the LSE at the time, but a few years later on fitted the TC to another ZF (from a D1 diesel) to mate up to the HS2.8 (300Tdi). I recall having to change over a shaft in the V8 ZF but I just can't recall whether it was for the ZF to accommodate the D1 TC or the HS2.8.
No idea about D1 and D2 TC differences, except that early D2's had a centre diff but not the levers to operate it.

I probably would have fit a gearbox that you could tow in top gear with without any issues

I can tow all day quite comfortably in 4th and within reason 5th without issue. I'm happy with my r380 behind my 4bd1/t. Saying that I'm always searching for a possible better option. I happen to have a d2 transfer case just have to remove it from a d2 I have for parts. I'm also happy for people to jump /hijack my posts as we all learn/ Baz

Perhaps look at the Tremec tr4050 conversions available for the 4bd1/lt230.

Do you know of an adapter for the 4BD1T/Tremec TR4050. I heard Advance Adapters are going to make one but have stalled on the research.
