[Webby the Bear]

My auto box is shifting absolutely fine. Cars on 112,000 miles but never had an ATF change. I went to top the box up at around 100,000 miles and even though there's signs of a leak (at the tail of the GB where it meets the prop) it was virtually full and took hardly any to fill.

I have read that on high mileage vehicles (I'm sure in omega terms mines still a baby) that changing the fluid can actually cause the gearbox to fail shortly after.

Has anyone experience of this happening?

Cos if not I'm going to siphon the fluid sometime after Xmas and put new in

I have no experience of this but i fail to see how a ' oil ' gearbox or otherwise is sealed for life .... we change engine oil so why not gearbox oil ?

[biggriffin]

O young bear.
 buy a set of sump gaskets from jpat, drop sumps, remove filter and clean, blow cooler thro, then refil with 8 litres of dex2/3. I use shell spirex(donax).

The main reason why you change engine oil regularly is because it gets dirty from the combustion process. Gearboxes don't suffer from this, and so oil changes aren't required anywhere near as often. But I do agree that considering them to be sealed is a bad idea.

I think that rumour about people having box failures soon after is down to using the wrong oil, or, let's be honest, the main reason for most people to change their gearbox oil is because the thing isn't working properly. When people say 'I did that gearbox oil change thing, and the thing still broke. moan. grumble.' perhaps fail to mention the thing was on its last legs in the first place.  Not many people practice the 'preventative maintenance' that many do on here.

The dealer I purchased  My Merc from believes in preventative maintenance, the auto box oil was changed along with fuel air & pollen filters also sixteen new plugs engine oil & filter . I will keep this maintenance up to date, my old 2.6 never missed a beat in 65,000 miles, serviced as per schedule.

ATF is a Mercedes Service item and is scheduled as such. It's details like this that makes Main dealer servicing SEEM expensive. And why going diy/back street on a previous fmbsh car is a bad idea... little bits get overlooked.

Believe as long as it's Dex 3 then it's good to go.Filter[if wanted/needed]and gaskets for both sumps available through ABS at reasonable cost.

[Shackeng]

But if you're going to change it Webby, just syphoning will only get a limited amount out, and will not clean the filter or identify any other issues which may show up in the detritus in the sump. It is not a difficult job to drop the 2 sumps and clean the filter.

[Webby the Bear]

Thanks guys. To be totally honest I just wanted to get away with a siphon. I know your right of course. I'm just a bit lazy lol

Having said that it would be nice to see what's on the magnet

Replace the filter if u already in there

[biggriffin]

Replace the filter if u already in there

Filters can be cleaned, if looking to save,money.
