Transmission Coolant Lines
I went to my indie to do the ATF pan flush and he removed the bottom panel, he found there were some oil on the panel. He then found out that the upper and lower coolant lines were "wet, sweating".
He aborted the pan flush and said I should replace the 2 coolant lines. He asked me to get the 2 coolant lines and he would replace them for 2 hours labour. Is this reasonable?
I called the dealership and both parts are back-ordered and they will have to order from Germany.
Part numbers: 209-270-0696 and 209-270-0796.

Funny. I went to the local dealership to order the parts and talked to the mechanics. He told me he never changed the transmission coolant lines for a CLK. Maybe they never serviced a 12 years old CLK!

I did look at it. Both lines were rusted and "sweaty".

NO LONGER ACTIVE
"Sweaty" makes no sense on the transmission cooler makes no sense! Humidity in the air condenses on objects that are cooler than the ambient temperature (the way a cold drink glass sweats), but the transmission lines should be hot, even the return line from the cooler will be warmer than ambient temperatures. Are you sure you aren't looking at the AC refrigerant lines as they enter the condenser?

The indie to.d me they were the transmission coolant lines and showed me that both lines were rusted and sweaty. He specializes in Sprinters which share the same 722.6 transmission. Actually, I see a lot of MB in his garage in the past 1-2 years.

The 2 cooling lines were replaced this afternoon. Together with the pan flush, it took 2.5 hours. 4 litres MB ATF were used. Also checked the 13-pin pilot bushing, it was OK (dry).
Because of the ATF change, the car is now super smooth.

Labour: $240
So, about $600 in Canadian funds. Cost of parts includes 15% discount.
One note is I did pan flush twice and they both took in 3.5L This time it took full 4L, because of the cooling lines.

When I changed ATF myself, I let it drain all night and I had 4.4L in the container pan by the morning.
This was the difference:

The work was performed by an indie. If I get this fixed in the Mb dealership, it would be more than $1,000.
Not sure why, MB parts are so much more expensive in Canada than US. Unfortunately US online stores do not usually ship to Canada.

Yeah I remember that. I was lucky by having my brother work in the US and live in Canada so that's how I used to get all the parts and fluids for cheap.
