One of the automatic transmission oil cooling lines to the radiator in my car is corroded.
You can see it in the photo below.




In the picture below it is line no. 3. My mechanic said so.




I would like to replace it, but I can't find such a part for sale, neither new nor used.
Can you please help?

 

I wonder is Mercedes has an equivalent for the SLK320?

 

I found these used ones taken out of a Mercedes SLK 320 (R170) car - a complete set.
https://allegro.pl/oferta/mercedes-s...ow-17192138017
In this offer it is written that it fits exactly this car:
SLK (R170) 320 (170.465) (M 112.947) 3199ccm 218KM/160kW 2000/03-2004/04

But they look different than in the picture above...
Maybe because my car was manufactured in 2004/05?
I would gladly buy them if I was sure they would fit.
Has anyone here perhaps replaced these oil lines before and could give some advice?

 

I wonder if a transmission repair shop would be able to make those lines. Like a brake repair shop can.
Perhaps if you take the information to them, they might be able to locate those parts.

 

I was looking for a complete set of oil lines for this car earlier and it's hard to find.

But as for this single corroded section of line, there are offers on eBay, for example this one:
https://www.ebay.com/p/253551847?iid=267236852861

So I bought it.

This section of oil line no. 3 is easy to buy, the other sections are hard to buy. It seems that this section no. 3 wears out the most.

 

I have a manual transmission, so I don't have those lines.

 

Unfortunately, after a few days, the seller informed me that he could not find in his warehouse the oil line no. 3 that I had bought, so he refunded my money.

However, it turned out that this corroded section of the oil line is part no. 2 in the above drawing, not no. 3.
Interestingly, I managed to buy this oil line no. 2 yesterday, new, and to be precise part no. 05099379AA in a Polish store.
It cost me $33 including shipping.
I thought this part was impossible to get...
Today the courier delivered it to me - here it is in the photo below. I hope it will fit.



I also bought these used oil lines pulled from a Mercedes SLK320 (R170), and trying them on by eye, it turned out that they were the same oil lines as in my car.
This offer was missing the final section of the oil line, the one at the radiator itself, but I managed to buy it new in a Polish store, as I mentioned above.

 

Keep us posted,

 

Yesterday my mechanic replaced the corroded oil line no. 2 at the radiator with a new one.

I also decided to buy an original Mercedes oil change kit for the 5G-TRONIC 722.6 automatic gearbox, i.e.:
MB 236.14 oil,
gasket under the pan,
oil filter,
drain plug gasket,
plug.
It turned out that the old gearbox oil filter had the year 2004 written on it, which means that the oil in this gearbox had not been changed since new, i.e. for 21 years...

At the same time, the oil in the rear axle (differential) was also changed: Motul SAE 75W-85.

This car repair cost me $500.
