Thunk when it shifts from second to first gear when slowing down and shifting down by itself. Almost feels like a stall. There is also a clunk... I want to say at the driver side rear.
When i took it to the dealer for an oil change and there free 128 (or 126?) multi point inspection; they said everything was good!
I know alot of cars run without ever touching there transmission fluid, im also curious how many miles should i push before a flush?

The trans coolers are for 7at users. That downshift I have experienced once or twice myself, does it happen when you have like a very light throttle while just barely cruising down a residential street (like if you were looking for an address)? I have only had it happen maybe once or twice and it seems that your right at a load range where the trans isn't quiet sure what gear it wants. After I had a tune done I have not had this happen since as the trans seems to hold gear longer.

Is a cooler necessary? Maybe not but a Stillen at cooler is like 300.00 and a 7at trans is like 9k. So I do track my car so I give it every bit of protection I can, flushed trans at 35k with amsoil and installed cooler when I bought it and will probably to regular drain and fills every 30k after.
