Radiator Replacement

I'm new here and I believe that I have a w209 body but I'm not really sure. It's a 2006 CLK 500 cabriolet....?

I have a very slow coolant leak that I believe is coming from the radiator.
I purchased a replacement as it doesn't seem like that bad of a DIY job.
One thing that concerns me though it the fact that the transmission line is hooked into the radiator and I will lose fluid once I take the old radiator out.
I don't see any way to replace the lost fluid or even check it....any help with this. It's a 7 speed automatic transmission.
Thanks,
Peter B

Its not difficult, just annoying. Not a lot of space to work in the front of the engine.

yes you'll loose some tranny fluid. I'm not sure how to 'push' the fluid into the 7 speed. My 5 speed can be filled from the top. I think I lost maybe 1/2 qt or less.

yes, I watched a couple YouTube videos and I'm pretty sure I can handle it. With the 7 Speed tranny there is no fill on top of the engine to top off the transmission fluid and I'm not even sure how to check it.
I just may take it in somewhere afterwards to get the transmission serviced as it's coming up on 95,00 miles and it's probably a good idea to get it serviced anyway at this point so I know it was done unless I find a way to check the level and fill it from the bottom??

I would go with what you said. Fill it from the bottom if possible. You can try and collect the oil that spills once you remove the lines in a container big enough, then you can see how much you lost and need to replenish the system with.

Update:

Well it was as I suspected, a radiator leak. What bothers me is that the seller lied about it.
From my initial diagnosis, I went ahead and purchased a replacement radiator for $105.00 and was going to do the job myself.
However, I found a really good mechanic who installed it very reasonably....Labor, radiator fluid and tax came out to $371....so materials & labor only ended up to be $475.00 Total.
He did a great job and I'm happy that the car is fixed now and I didn't get ripped off on the repair.
