You don't need to plug the radiator

What he said ^^^^

I plugged mine, in case I ever wanted to go back or use the stock cooler in series. Just keeps dirt out from driving.

Why go back? To much work to go back

We people who have cold winters. It sucks

Going back and running in series requires about the same amount of work for me. It would need new lines regardless of the route I took.

Gotcha

I just picked up a 08' 2 days ago, of course coming from previous grand prixs the trans was a concern of mine. My question is simply wondering if this one possibly has a trans cooler? I havent spotted the temp go above190*, usually is in the 170* low 180s.. Ive done a lot of driving - have not beat it at all though, not once... ive scene .29G so far, just curious as I would have expected higher temps on the highway drives. Are these normal opperating temps?

Go do the GXP commandments.

boost, who needs boost haha. but yes this thread is stickied in the ls4 section fyi

well I'm assuming your referring to the tranny cooler. it keeps the 4t65E-HD from over heating or getting to how

the shift kit fixes terrible shifting that the same tranny has

the transmission cooler that i did the write up on? if that is the one you are asking about the 4in model should fit no problem. may need to bend the metal brackets some depending on where the holes are in front of the radiator

**** at that mileage I'd wait till it poops the bed
