L322 transmission oil

[harlie]

Hi Guys

I would like to hear thoughts on the Range Rover L322 Transmission being a "Sealed for Life" unit. Land Rover states that the Transmission oil change is not on the service schedule at any point, I also see people stating that it is a good idea to change it - so what’s peoples thoughts with a 100k transmission that feels smooth but we know hasn’t to this point had an trans oil change?

I'd be doing a filter & oil change.

Have you checked the oil condition at all?

Yep, i'd recommend having one done too. The gearbox is not exactly cheap if they do go BANG! so for the cost of a fluid & filter change it'd be well worth doing. There have been enough posts about L322 gearbox niggles that if yours is working flawlessly at the moment it'd be money well spent to help keep it that way.

Take it to somewhere that has the proper kit to fully flush the ZF box (presuming yours is a v8), if you just drain the fluid and replace in the gearbox itself you only get about 1/2 of it out so it's best done connected up to the proper machine for the job.

thanks guys - it is a car (diesel) I'm looking at so no I have not checked it. Is there an easy way or is it something that should go to a LR specialist

I rang ZF and found thier local repairer and mines booked in for a flush/service early Jan next year.Sealed for life is like long life coolant,waste of time. Pat

Hi Guys – sorry to bump this. Is it possible to check the condition with out draining? Is there a top level bung, how had is it to get to?

There's a level plug on the N/S just above the pan.
According to the manual, the level is checked with the engine running. Oil should dribble out when at the correct level so you should be able to see the colour.

The diesel uses a different gearbox if memory serves, GM 5L40-E as opposed to the ZF one in the petrol models.
