Titan2087

Hello all, I am new to the forum and have recently purchased a new 2010 Silverado regular cab 2wd automatic with the 4.3l v-6 with out a tranny cooler. My first question is what temperature ranges should the automatic transmission run my truck runs between 180 to 215 once warmed up according to the dash read out that comes with the truck are these normal ranges? I live in Az where the weather is 95-110 depending on the day. Im not very farmilar on automatic tranny operation as this is the first automatic iv ever owned and only because Chevy doesn't put a Manuel in there full sizes anymore.
2nd question is there any where i can download a service Manuel for these trucks?
3rd question are there any lube points on the truck or are they all self contained such as ball joints
Thank you for your time
