Transmission oil and fiter change
 

I going to change the transmission oil and filter in my 05 Silverado, 4door
pickup with auto transmission, 2 wheel drive 5.3, p/s, p/b, and air.
Mileage is 140.000 miles it had oil and filter change at 60.000 miles by a chevy.
dealer, is there anything I should do or look for when I have the pan down?
How much transmission oil will I need? and should I use synthetic oil?
I think it is a M30 transmission. CHUCK41

Just check for metal shavings in the pan really. There's a great write up on gmfullsize about changin it out usin the flush method.
