oil change auto box ??

Dutchroger · Apr 6, 2013

I have a p reg 300tdi auto.

I have had it for 4 years now from 96k now 115k. I am not sure when if ever the auto box oil has been changed. The question is do I bother changing all and filter which seems like a big job or just drain and refill with new oil.

Whilst I am at it I am going to do the axles and transfer box is standard EP90 ok. I was thinking of putting some liquid grease in the axles as well.

After 4 years I'd change it.

EP90 or EP80w/90

With the auto box does it need the screen changing and full drain or can I get away with changing the oil only.

I seem to remember somewhere reading that you can just drain and replace half the oil 4.5 l or there about.

How easy is either process as the Haynes manual just says take to a landy dealer

Hi,

You can only change 1/2 of it at a time without doing the filter. 4 years sounds like a long time between changes.

Even with changing the filter only 1/2 of the fluid can be drained.

To replace all the fluid at once can be done via the cooler pipes, which are hooked up to a machine designed to to that, The main dealer and indi I use has such a machine.

Some say the only other way is to replace what you can and later after a run replace the fluid again, not a 100% fluid change but near enough.

My fluid & filter (which is just a screen) was changed in 2000 and again in 2010 so ten years apart without any probs in between or after.

The next question then.

I am going to change the auto oil or half of it anyway this year next half next year. So do I replace 5-% with dexron 3 or 2. Does it matter ?

Cost is not the issue

Over the years It was Dexron 2 then 2D then 3, an improvement on 2D so 3 the one to use. It may say on the can Dexron 2D & 3 compatable or meets that spec.
