Put in the correct amount only.
On the first service at the Land Rover main dealer they charged me for topping up the gearbox oil ![]() |

This is going to start the same debate again, but here goes.
On a gearbox oil change the manual states 2.4 Litres for a 2.2L engined Defender and 2.2 Litres for a 2.4L engined Defender. So why the extra 200ml for the 2.2 compared to the 2.4 , after all it’s the same gearbox at the same angle ! Well it could be due to a typo in the 2.2 manual, or a typo in the 2.4 manual, or JLR may have decided that the gearbox would operate better with the extra 200ml . Nonetheless, when I drained the gearbox oil from my 2.2, and it had not been touched since it left the factory, I measured exactly 2.4 Litres, so I have followed the manual and filled with 2.4litres and had absolutely no issues. One thing to note, it should not have more than 2.4 Litres in it, 3.5 Litres is too much, however unless your gearbox is exhibiting issues then it’s likely to be ok. One thing you may notice is gear changes are a little slicker with less oil. Last edited by Ianh on 12th Aug 2025 5:02pm. Edited 1 time in total |

Probably better to the feel with correct amount over the 3.5 that came out.
I wouldn't worry about what you can't change. Cheers James 110 2010 XS Utility 130 2011 M57 bespoke Camper 90 2010 Hardtop 90 M57 1988 Hardtop |

Just refill with the correct quantity. It should be fine.

One thing you may notice is gear changes are a little slicker with less oil.[/quote] Back Ground Last year, the original engine self-detonated at 41,000 miles. The previous owner had a tuned the engine, but I’m not sure who did it. I had a brand-new crate engine installed, Last month, I had the transfer box and intermediate shaft replaced. The bolt in the transfer box sheared off, I can’t find any mention of gearbox oil on the invoices, but I assume they replaced or topped it up. The reason I changed the oil was because the shift from 3rd to 2nd was very stiff. Before draining noticed the gearbox was covered in oil. After reading some forum responses, I decided not to add more oil and went for a drive yesterday evening. Guess what? The issue with the shifting is gone, and everything feels smoother. I checked the gearbox this morning and there are no leaks. I’m a bit concerned that the garage I spent about £15,000 (including the suspension replacement) with last year may have overfilled the gearbox but not 100% sure so will put in down to the joys of Land Rover ownership 😀 Thanks so much for your advice!

They used the filler plug as a level plug I expect which is how previous boxes were filled. Too much oil doesn't help changes. Cheers

No idea, that's what they told me was the issue. I had braked suddenly in town after that I noticed banging noise which I was told was coming from the transfer box and needs replacing. Matt
