Land Rover Transfer Case Sump Upgrade

When in extreme boggings or doing lots of low range work, the Land Rover transfer case oil can overheat, which could lead to premature failure of the transfer box. I decided to install a Global Roamer finned extended capacity cooling sump for my LT230 transfer case. This unit extends the oil capacity by 500ml and adds cooling fins onto the base to increase air cooling.

The old versus the new.

Installation complete. The sump is still located high enough to avoid damage. The chassis and handbrake drum are located lower so are more likely to be damaged first then the upgraded sump.

  1. Hi,
    I am thinking to install a similar transfer case but the it seems too close to the exhaust after installation.
    So, basically, instead of cooling the oil, the fins absorb the heath.
    Is there any way to evaluate Before VS. After (with VS. w/out)?
    Can you confirm oil temp has been lower after installing the new sump cover?

    Many thanks in advance,
