Thanks for the advice. After rebuilding the tranny once, four intake manifold gasket coolant leaks, three water pumps, along with the two fuel pumps and four alternators on my former '93 K-Blazer's 230K milesstill with original exhaust system and shocks.....I wanted to give this one every chance for a long & healthy run. So far so good. Thanks again ZX.

 

Would this cooler work on my 07 LS?

 

I don't see why it wouldn't. Ask your Chevy dealer. I believe the Chev accessory part number is 19171483 Transmission Cooler.
