Assorted CC Recalls
I figured the 10W30 Amsoil would be better here for summer time, as the temps here today hit 100F. The 5W30 suggested from GM is a gas mileage "gimmick" they have going, and nothing else. They even told me at the dealership to run the 10W30 in it to give it more hot weather protection. And with it being full synthetic, it will work just fine in what bit of cold weather we have here in winter. They also checked my electric power steering assist on the recall and found nothing wrong with my particular truck. They mentioned that some of them were getting "rubbed" on and caused the wiring to chafe somewhat, but not on all of them. Of all the recalls on mine, they have yet to find anything wrong for what it was recalled for in the first place. Seat hooks, power steering, receiver hitch, and the block heater cord so far to date. As for keeping the transmission oil cool, I guess you know these trucks with the HD towing package come from the factory with a great transmission and engine oil coolers built in to them. Trace your transmission oil and engine oil lines up to the front of the truck and you'll see the AC condenser coils. The top 10 rows are for transmission oil cooling and the bottom 10 are for engine oil. The rest of those rows in the middle are for AC freon cooling. Just press the INFO button on the DIC and you'll see the transmission oil temp pop up. Even on hot days mine does not go over 150 degrees. That is COOL for transmission fluid, and only an external transmission cooler can keep fluid that cool this time of year. In winter it rarely goes above 120F. You cannot run trans fluid to cool. Smart move on Chevrolets part too, with a 7,000 pound tow capacity, they'd better keep the trans fluid and engine oil cool. OK, I'll just have to wait and see what they do with what ever it is they ordered the part for it last week. I'll be sure to let you all know here, in an effort to pass along some helpful info to someone else. This is a great forum , with great people contributing everyday. Good job everyone!
