Is there any real need for a tranny cooler on a G56? I just replaced tranny and am debating on putting on coolers for the PTO covers.....thoughts? I was jsut thinking this is already an aluminum case so how much can they really help?

 

I've never seen mine get over 225°...and that was after 40 hours of straight driving pulling 10k+ in summer weather at 80 mph.

I'd say there are more important items to spend the money on...

That was exactly the kind of info I was hoping to find out. anyone else?

 

Coolers don't add much extra anyways....use a top quality synthetic you should be fine.
