Radiator and transmission cooler question

I just acquired a 2007 z4 3.0si and I’m in the process of doing a cooling system refresh. Replaced the water pump, thermostat, and expansion tank including hoses. I want to replace the radiator but not sure which brand to get. Anybody has suggestions and first hand experience with the brand you like? Also, my transmission oil cooler is leaking so I want to replace that too. Anybody use the mishimoto oil transmission cooler for the n52? Thanks for your response
 
I’d stick to a brand like Nissens for the rad. Been around for years and are well made.
Gearbox cooler I’d imagine it’s OEM only. Never looked for one so they may be made by different suppliers
