Trans fluid looks like strawberry shake.

Don't post on here very much, usually just browse but looking to see what your input would be on this.

Just installed a new trans, along with new trans cooler. Got roughly 300 miles on it and truck left me stranded. I drained the trans fluid and it looks like a strawberry shake. I attached a picture. This obviously happens from either water or anti freeze, but how can I test it? Would pressurizing the cooling system help me confirm my radiator is bad? Everyone I've talked to says its the radiator, but I don't want to replace the radiator without verifying and then still have the same issue. When I think about it the only place they do intersect is the radiator, so makes sense. Just looking for other input.

Let me know your thoughts.
Thanks

Should be able to disconnect the trans lines at the radiator, and pressurize the cooling system. If the cooler inside is bad you will get coolant coming out the trans line bungs.
