The transfer box is generally drained - it will drain anyhow once the lower bolt that fixes it to the adaptor housing is removed.
The transfer box is fill to spill, so open the filler plug (1/2" square drive), located at the back side next to the handbrake drum, and check that is filled with gear oil. You can use a cable tie (ty wrap) as a make shift dip stick. 1988 90 Hard Top, 19J Diesel Turbo, Shire Blue - Restoration ongoing 2012 90 CSW, 2.2TDCI, Santorini Black |

Yes I've changed it before- that fill plug is tricky
I'll check the level with a cable tie like you say - cheers ! I'll make sure there is oil in there for now & do another change soon if there is oil in there Assuming if there was no oil refilled it would be red hot or even failed on the way down the motorway |

Family member had his TC melt after driving from Manchester to just south of Naples in Italy with very minimal stops. I suspect it was either never refilled or was so low on oil. First to fail was the intermediate bearings that welded to the intermediate shaft. Intermediate shaft started spinning on the aluminium and they did not drive too far until everything seized up. In Neutral it could still drive on low gear as the Low gear seized to the shaft. So the TC can take a lot of punishment. But I hope the best for you.
Mind you, my TC does get a little hot, but not enough to 'smell' it. 1988 90 Hard Top, 19J Diesel Turbo, Shire Blue - Restoration ongoing 2012 90 CSW, 2.2TDCI, Santorini Black |

Level good & used cable tie to check oil level is somewhere where I'd expect it to be - it's not a fill to level box on these im told and is only slightly below so assume it's near the recommended 2.3litres - oil looks clean and feels somewhere what you'd expect for the right oil in there
I've realised the smell is likely the exhaust joining compound they had used to re assemble the exhaust join A breif drive this morning and no smells |

There has been some discussion on the LT230 fitted to Puma oil levels on this forum.
AFAIK, all previous Defender models with the LT230 transfer box was fill until it spills. The Puma engine/gearbox assembly is nose up, so that means that even if it is filled until it spills, it will have less oil than the transfer boxes pre Puma. I think I read (possibly a hypothesis), that Landrover specified less oil in Puma TC to reduce chances of oil leaks from the rear output shaft, given the nose up installation of the engine/hearbox assembly. But I am sure there is a tolerance on capacity, so a bit less or a bit more will not hurt. But surely, having less oil to start with will get it critically low sooner if there is a leak. 1988 90 Hard Top, 19J Diesel Turbo, Shire Blue - Restoration ongoing 2012 90 CSW, 2.2TDCI, Santorini Black |

After much research and deliberation I filled the transfer box on my Puma exactly the same as I have on previous TD5's and 300TDi's.

Thanks guys!
Think I'll top it up until it dribbles from the fill hole when I'm next under there! It's not too far under the line so likely the specified 2.3litre I'm the sort of chap that'll check it 6monthly or yearly so not a bit issue aslong as I know they refilled I'm less worried |

I'll add a little to this as I did have a quick check of transfare box temp after a run out in mine ..
A couple of shots with the thermal camera.. it may have been 5 or 10 min after I stopped but the transfare box looks to be about 60 degrees C.. Just for fun I'll add another looking towards the sump👍  Click image to enlarge Click image to enlarge |

Use the stick on thermometer strip you can get from RS to monitor your transfer box and gearbox temps.

The transfer box doesn't need to be removed to change the output shaft so the oil doesn't have to be drained or lost. Obviously you would expect the level to be checked as a matter of course on completion of the job. |
