It is in the bottom of the transmission. You will have to remove transmission pan and you will see it.
No, You must remove the transmission pan to drain the fluid.
just about any Chevy trans, a TH350 or a TH400 are the most common and will both fit. as far as engines and transmissions with Chevy's there just about all interchangeable without to much messing around. only difference with a TH350 to a TH400 is that a 400 will take higher horsepower/torque. but for most stock applications a TH350 will be fine , oh and the TH400's are slightly longer to.
if the tranny is completely empty of fluid about 12-13 quarts
NO. You must drain it out to the correct level. To much fluid will damage the transmission before it pushes the fluid out of the vent tube.
Assuming this is an automatic transmission, pull the dipstick out and read it, it will tell you the proper ATF to use.
Assuming it is automatic, read the dipstick, probably Dextron III.
Automatic? Read the information on the transmission dip stick, it will tell you what type of fluid to use. Standard? Use Mercon.
any run of the mill PS fluid can be used in a Chevy truck/SUV. in a pinch u may sub in ATF (Automatic Transmission Fluid.)
While the truck is running in idle pull out the dip stick and read it.
under the truck, on the side passenger side of the transmission case is a screw-in bolt for check/fill
