Hi,
I bought a tan 2004 Bonneville SE last month with 65k on it and this site has been a great help with maintenance. So far I have replaced the gauge stepper motors and all the backlights in the dash. Yesterday I added a transmission cooler and when the weathers warms up a little I plan to flush the coolant. We replaced and older van and my wife liked the Sunfire she had, so it wasn't too hard to convince her to buy a larger Pontiac. I love all the room to work around the engine

Welcome to the forum! Looks like your keeping up on the maintenance which will ensure reliability for years to come! I have been very pleased with my trans cooler, reduced trans temps about 40-50 degrees when its about 95-100 degrees out.

Welcome to the club!

Do you have any pictures?

I need to get around to installing a trans cooler soon too.

Welcome to the club! Glad to hear you're keeping your new Bonne up to speed.

I want in on this endeavor as well!

Thanks
FYI the Derale brand plate & fin cooler does not come with the right size adapter for the radiator. I spliced it in at the rubber portion of the line and ran the hoses under the radiator. I put the cooler as low as I could on the driver side of the ac condenser and I had just enough hose.
