I bought a used Mishimoto Radiator from someone on Facebook for cheap. I messed up and didn't realize the difference between the AT radiator and MT radiator, and I now have an MT Mishimoto radiator. At this point, I like the price I paid for it because it's pretty new, but I need to get a transmission cooler.

I wondered what the best option for a transmission cooler would be if I mostly DD it and plan to track it twice per month on average when the weather is warmer.

I was looking on Mishimoto's website, and they have one that is universal and is only ~$100

But I also noticed other options which were confusing me.

There's the burger tuning one which is $400.


There's also this Amazon/eBay brand


Should I just get the Mishimoto one(purely because of the brand), the Amazon/eBay one, or should I buy the Burgertuning one that is 4x the price?

I just want to understand how much of a concern Transmission fluid temps are in the N54 AT and whether I need top of the line or not.

Also, if anyone knows another way of using the Mishimoto radiator without getting a separate transmission cooler unit or has different options for a transmission cooler, that would be nice.

Any opinions? I ordered the Mishimoto one so I can just start installing this thing.
