Good But not Best.
I dropped a star. The lower connection was for the ATF cooling line was corroded and o ring would not seal. Not time to return so added an after market ATF cooler. Price was good shipping one day behind due to weather. Recommend checking items before shipment. The way the lines connect are a pain with small clip to bad GM did not use the old screw in flair fittings. The radiator was just like the original.
