Service and auto box oil change

[05XC90]

Going to get my 05 XC90 D5 serviced shortly.
141K on it. I've been told gearbox is sealed, but that changing it is a wise option!

-What is the best engine oil and gear oil to go for?
-Is there any specific way to change gear oil?

I've a relative who's a mechanic and he'll be doing the work on a proper lift etc.

Cheers

Re the auto box, changing the oil is very worthwhile BUT YOU MUST USE JWS3309 SPEC OIL AND NOTHING ELSE


Couple of videos showing each but the first is on a 5 speed auto and the second on the later 6 speed auto.

5 speed you refill via the dipstick tube on gearbox.


You have 2 options.

1. Sump Dumps which is where you remove the gearbox drainplug and release the sump contents ( only about 3 ltrs will come out and a further 4 will remain in the torque convertor) . Fill back up with fresh fluid to the correct level and then after a couple of hundred miles repeat the process and keep doing it for about another 4 times.
Yes you are mixing new oil with old BUT it is gentle on the gearbox and eventually you end up with fresh fluid.
Think of it this way, if you poured a glass of orange juice and drank half and then topped up with water and then drank half and topped up with water, eventually you would be drinking just water.

Cheers dude, it's a 5speed auto box. Would it be best get the oil from dealer or just regular motor factor do you reckon?

Loads of us on here have used Mannol JWS 3309 from Ebay ( from a German Seller ) and it has been fine. Toyota JWS3309 spec oil is also fine as will Volvo but the Volvo stuff will be expensive.

Comma do the correct spec as well.

Hi,
Had my gearbox oil changed last week by Hutton Bothers Volvo Specialist at York, they advised the sump dump method as it was much simpler/cheaper and I had no Gbox issues, just preventative maintenance. (6 speed box with no dipstick, hence why I entrusted it to them).
Genuine Volvo oil price was £15 per litre inc VAT.
One hours labour included VIDA counter reset.
Diference is noticeable with a more positive change.
Main dealer wanted £350 for the job but that included flushing everything through and re programming the box which did not seem necessary as there were no faults.

I've just done my first sump dump. But don't bother getting under the car. I got a 12v pump from Lidl a few years back. Pipe down dipstick hole, pump out until it stops coming, got 3L out.
Then turn pump round and pump in 3L of fresh. Took about 45 mins all told. This is the longest it's ever taken because the oil was so cold.

Assume this is the correct stuff

Anyone tried carlube?

It says it's JWS 3309 so ought to be OK

BUT

Personally I'd use more of a "Brand" oil - but that's just me.

There's some interesting views expressed here

Maybe think about it from the perspective of risk vs reward.

It's difficult to feel certain about the suitability of another oil spec / manufacturer, other than the one from the dealer is by definition the correct one. The difference in cost is £50-60. Given that it would be a little excessive to change the transmission oil more frequently than every 2-3 years, then it works out between £20 and £30 per year difference to use the genuine Volvo oil. Consider this against the cost of repairing or replacing a prematurely failed / worn gearbox.

This is not because I have money to burn. Only this week I took a punt on an eBay supplied Osram headlamp bulb, as there's over a £100 difference between that and the dealer supplied part. I don't have to have the best, "just because". The difference is, if it turns out to be a cheap knock-off which only lasts 12 months, all I've lost is £35. It won't have caused damage to other components which would cost northward of £2500 to replace.

You can overthink things.

Good reputation on here, genuine branded lamps at good prices.

No gearbox juice though...
