W211 E270 gearbox oil change

[motocod]

Hi Folks,

My 2005 E270 is currently on just under 150,000 miles, and to my knowledge has never had the gearbox oil changed. My understanding is this should be done every 70k or so.

I've spoken to Coverdale in Newton Abbot about getting it done. They tell me that aside from main dealers they are the only place in Devon that have the equipment to remove the old oil. I'm not familiar with how it's done, or whether it requires specialist equipment, but they told me it would be about £350+VAT. Does that sound about right?

Thanks in advance!

E270 has the 722.6 box and TC without a drain plug, £350 plus VAT seems high to me, you can get 7l of oil, filter, gasket and tube clip for about £130 from the dealer including VAT.
Ask them for a breakdown of those costs.

Give Steve at Avantgarde Mercedes (MB Indy) a ring . Clevedon near Bristol . The price you have been quoted is MB main dealer prices ...ouch

Thanks for your reply.

A bit of googling seems to suggest that no specialist tools are required - seems like it's just a case of pumping in the fluid until it runs out of the overflow.

I was led to believe it's something only a specialist can do, because the old oil needs to be sucked out, and if you merely drain it out quite a bit remains in the system, and that ends up contaminating the new stuff.

Can anyone confirm this?

That's all totally wrong buddy . If you have the 5g gearbox you don't need a pump and there isn't a hole that you keep filling it up to . Have a read in the DIY section for this job , it is quite strait forward.
There is also a lot on YouTube , search Mercedes 722.6 gearbox oil change .
If you have the 5g box (rather than the 7g box) you will also have a dipstick tube in the engine bay with a black cap on it

Thanks Wighty.

Presumably by 5g and 7g you mean 5 speed or 7 speed? Mine is a 5 speed.

I'll take a look at the DIY section - apologies, I didn't realise there was such a useful resource!

Looks like this might be the "how to" here - sadly the pictures have disappeared. I'll take a look at youtube later...

That's right 5g is "5 speed " buddy . Plenty in the DIY section and YouTube , have a good research and then come back to fine tune the advice , sourcing of parts , type of oil etc .
By the way in my picture in the post above , if your black cap has a red tab like mine does you "may" have had a gearbox oil change (it may just have had the oil level checked and the black factory tab replaced with the red one .
You are lucky if you are considering DIY on the 5g box , it's easier and cheaper than the 7g box

I think forum member Umblecumbuz has done a good DIY write up on the 5g

 

[motocod]

Great, thank you very much!

Does anyone have any thoughts on there allegedly being lots of oil left in the torque converter if it's not pumped out?

Yes , half the oil is in the TC . Forum member Jim2 did a good write up last year on one of his threads . He disconnected one of the oil cooler pipes I believe and waited until the fresh oil pumped through .
I haven't done this , you could empty the sump oil , then refill with 3.5L of oil , run the engine to circulate it and through the gears . Then drain the sump again , change the sump oil filter and refill again , this would be 75% change .
I use a Pela 6000 pump every year or so , to just pump out 3.5L via the dipstick tube and refill with fresh oil (cost £25-30) , but I changed the filter a couple of years ago anyway .

Moderators , I must have pressed "post reply" 15 times before the above post actually posted .

Thanks Wighty. I'm not looking to do it myself - I don't have a means of getting the car in the air, so I'll have a chat with my local garage and see if he feels up to the job.

Before you do , get a quote from Steve at Avantgarde Mercedes , Clevedon . He will do a 100% change and do it correctly

 

[motocod]

That's very tempting, but for me it's the issue of having the time to get the car up to him - it's about an hour and a quarter from where I live on the edge of Dartmoor.

MBS Southampton, Colin like Steve has an excellent reputation for any work MB related, both have STAR so can fill to the exact amount.
If you go to the local guy he can do the job (my village mechanic did mine once,) just refilled the exact amount that came out, not the best solution but gives a 65% change right off the bat.

Thanks Matty.

My local independent specialist have just quoted me the following:

• Gearbox oil and filter £245+Vat
  
• Engine oil and filter £80+Vat
  
• Fuel filter £48+Vat
  
• Air filter £46+Vat

I'll do the air filter myself, as it's basically a ten minute job.

 

[V6Matty]

I’d say that’s a reasonable price all in, maybe a little high but not over the top actually.
IIRC my E270 was a similar price and that was 3 years ago

 

[motocod]

Thanks Matty, that's just what I needed to know. Fuel filter looks like a simple job too, so I'll do that, and let them do the rest.
