Common problem. The solution is the completely bypass the stock cooler and setup a separate external cooler.

how would that be done? Is there a kit or something like that or would I have to fabricate something

I used a Hayden transmission cooler on my Mercedes. Here's some pics from my C320. My E320 is very similar.
​​​​​very happy with the results.

so would i just leave the 2 slots in the radiator open

yup that's exactly what I did. The c320 used the exact same type of clip connector in the radiator and the upper line kept popping out. Something had to be done and later I did the same thing to the E320. Here's the E320 with the Hayden 679 trans cooler. You can feel the heat pouring off that thing after a drive.
