Manual 5 spd VinW

Hello All: I have a 2002 Silverado 1500 4.3L,, very basic truck, use it for work all the time. 92k miles, manual 5spd transmission, need to look at changing tranny and clutch fluid. Vin W, Is there a drain plug on the tranny, and where is the fill plug, or do you fill it thru the drain plug? I do most of the maint myself,, is changing the clutch fluid doable by myself??

Thanks in advance..

Dale

The drain plug is on the bottem of the tranny and the fill plug is on the passenger side of the tranny.
