V70 AWD Transmission: Xc 70 2003 auto transmission fluid change/flush

[Georgeandkira]

If that pump gets you to do exchanges, it is indeed a good thing.

Many will argue that unscrewing the drain plug allows the sump's contents to flow out fast with a higher likelihood carrying dirt out with it.

I'd use that pump to refill as the process is so slow.

It's less than £15 too.
I've used it for a few years now. I don't do the Gibbons method, but remove a few litres at each service and fill up.
Pump the old out of dipstick, then reverse pump and pump the new in.

I couldn't see the pump in my local Lidl - is it still on sale at yours?
is this this same kind of thing?

So, some years later I'm looking at doing this on my 2003 xc90 d5

If i decide to go Gibbons, can i remove the hose that runs from the bottom of the cooler to the gearbox, at the gearbox?

I'm thinking the fluid will then be pumped direct from the box to a bowl where i can measure whats been pumped and refill.

I think this may save finding a suitable hose and be less messy

You will have to deal with the oil coming out of the cooler that way?
Easier and cleaner to use the top one.

For my XC70 D5, I bought a cheap washing machine drain hose off flea bay and it fits perfectly over the cooler top pipe. To ensure no leaks, I put a jubilee clip around the connection to stop it coming off, just to be safe. However, it seemed it would be ok without the clip.

Just a simple case of starting the engine, letting it pump a litre or so into a container and then stopping the engine. Top up with the same amount as measured that came out, via a funnel in the auto box dip stick tube. Repeat as often as is felt necessary.

Always check the level at the end after a quick trip around the block. Very quick and surprisingly easy process. Better than a sump dump in my opinion.

Agree, can all be done from up top.
I used two identical milk containers on the bench, dirty oil in one and top the clean one up next to it to the same level, really easy.
Best to have a spare plastic hose clip as they can break if old and brittle.

Agree with luggsey. Definitely worth getting the green clip and O rings, just in case. Else you could leave yourself stranded.

I bought some, but never used them after removing the top connection carefully. Nothing broke and it didn’t leak when I pushed it gently back in, after lubricating the O rings again with some clean transmission fluid. Car is 15 years old and 114,000 miles, to give you an idea how they hold up.

palwing: You reused the 15 year old O-rings? My green clip didn't break but those pudgy little O-rings hardened and there was no way I'd reuse them.

Honestly, the biggest thing to make this job easier is a source of plastic tubing. Some hardware stores have spools of differing sizes, Some don't.

I found a large roll of clear at a lawn sale. If England wasn't so costly to ship to I'd gladly send you pieces.

Go to Lyndhurst, NJ and you'll find an older fashioned car parts shop which has all manner of fuel line, heater hoses, windscreen washer line, vacuum line etc. on spools.

Hi Georgeandkira

Yes, I tend to agree with you about replacing the O rings. It was my original intention, hence why I purchased some new ones. However, on the day, the clip and O rings looked good so I thought I would just poke it back in. If it leaked, I would have taken the connection out again and replaced the clip and O rings. However, surprisingly it did not and over 1500 miles plus a few months later, it’s still not leaking so I will leave it for now. However, I might put some more oil through the system one day, if I am well enough, as I have only flushed 4 litres through so far and I think a few more litres wouldn’t go amiss after this mileage and age. Looking at the fluid that came out, I don’t think it had ever been done before.

Ref the pipe. Yes, there are many options and your plastic tuning idea is shown on YouTube. Guess it’s what works for you at the time.

Hi all. Just had my 16 yr old grandson do a Gibbons method oil flush of my 2005 D5 XC70 5 speed auto, with 115,000 miles on the clock. I used the Mannol ATF fluid advertised on Ebay. 10 litres for £32 inc p&p. That’s how easy and cheap it is to do.

I had a 3 litre sump dump carried out by my Volvo specialist back in January and I did a 1 litre Gibbons flush soon after. It did improve things but the change was still lumpy at times between 1st and 2nd when hot. However, it was very intermittent depending on how you used the throttle.

My grandson flushed 9 litres through today (took about an hour) and the oil was very brownish and cloudy. Even after 9 litres had been flushed, the oil coming out was still brownish and cloudy, which was disappointing, but there was at least a reddish tinge to it and it seems more fluid like come the end.

After a very quick test run with hot oil, 1st to 2nd can still be randomly lumpy but nowhere near as severe as originally. The other gear changes are silky smooth as always and almost imperceptible. Maybe another 10 litre flush until we get red clear oil coming out might be worth doing?

The question is, I have read how on later models you have to reset something to tell the car it has new transmission oil. However, I have not heard of this on the older models. Some posters have mentioned that some gearboxes do a self learning process after gearbox oil changes. However, I would be surprised if it applied for my car.

Anyone know?
