    GU Transfer case

    Are all GU transfer cases the same from 4.2's through to the last of the 3.0's? With the same ratios & mounting patterns? What might one in good condition (low mileage or rebuilt) be worth?

    I will need to decide to keep the NP205 case.or switch to a Patrol one on the OKA. Not yet sure of the pros/cons of going either way, just that both types are used.

    Go the Patrol one, at least you'll have a small Nissan bit of reliability in threre. . TBH wouldn't have a clue about the other one so don't take my advice . . .

    Please don’t take this as gospel Cuppa Mate but seem to recall the exact same transfer case code throughout my entire GU Gregory’s old manual which covered 2.8/3.0/4.2/4.5/4.8 I believe but wasn’t searching properly for your answer, just possibly recall noticing a trend.
    Think it’s the GU 1998 -2014 Gregory’s manual somewhere deep in the shed sorry

    Its only the adapter housing that changes for the 2.8/3.0 gearbox and the 4.2. the ratios and tc is the same.

    My god, thats a bitter pill to swallow, I guess the demand is low, production run low and R&D high. I had a Mercedes Benz Galendenwagen which runs a separate transfer case connected with a drive shaft. I would not recommend this configuration to anyone. The torque reactions are different from gearbox and transfer cases, and vibration was a huge issue. Also, there was a need for a torsion arm between the two to try and even things out. was a constant PIA as the vibration could start at anytime and Mecedes Benz didn't have a fix. Best to run a connected system so the mounts take care of the accumulated reaction as a system.

    Interesting to read that Phil, the earlier OKA's (XT) had a mated (married) Transfer case (NP205), the later LT's had a remote (divorced) Transfer case (Rockwell) which was renowned, apart from being incredibly heavy & 'sucking a *lot* of the Perkins motor's meagre power output & running very hot ..... to create an awful lot of vibration through the chassis. The one I'm buying has the earlier NP205 TC 'divorce mounted'. A relatively common (if there is such a thing among OKAs) modification to the later LT models. I didn't detect any vibration when I drove it, but I must admit that on the basis of keeping things simple & for the reasons you describe, I am leaning toward the 'married' Patrol TC. In remote rough country the fewer external shafts spinning in seals (which always) have a potential to leak just seems like a good idea to me. And I believe the Patrol TC may possibly give a slightly lower geared drive ratio too. The NP205's are apparently worth good money & selling one may just about pay for a Patrol TC & it's expensive adaptor to fit onto the Allison.

    There is an alternative to fit the NP205 direct on the back of the Allison (with another expensive adaptor) I think, so overall cost would be higher as nothing to sell to recoup cost, plus the Patrol TC has a great reputation & I've never had any concern about ours.

    @Cuppa, its a funny thing, vehicles can have identified issues as a model, yet some specific vehicles don't present with the issue.
