Factory trans cooler upgrade

Just replaced my factory trans cooler on my 2004 2500 HD with gm part number 89022577 . It’s twice the size and twice as thick. This replacement cooler was factory on 98 Chevy 3500 with 454 I just cut brackets off a old cooler and made them fit new cooler. I had about 45 mins into it the factory lines plug right in!
