Transmission Fluid Questions
 
Hey Ya'll,

I just had a quick question that may be considered a noobie question but just wanna be sure.
So this is the deal i want to change the transmission fluid myself in my 2003 chevrolet silverado 1500 4x4 and was curious on a few points.

1) how much fluid should i purchase to replace and are there any additives i need to purchase or should purchase in your best opinions.

2) Do i need to remove the oil pan or can that drain plug on the bottom of the pan suffice. doesent matter either way i can manage it but still are curious on the better choice between the 2

and 3) do i need to buy any gasket kits or filters for it to do a complete good job and any thing i should do to get most of the fluid out of my transmission. or would i be better off doing a tranny flush i have heard many bad things about it but i want to hear what you guys have to say.

thanks guys and again i am sorry if this seems like a noob question not worth your time but any help would be appreciated. :)

#1 I would buy 5-6 qts (a quick call to a jiffy lube(or the likes) will answer your question about how much) additives are a matter of opinion...I use Lucas.

#2 PULL THE PAN........This will tell you TONS about the condition of your tranny

#3 Buy a filter kit this will have a filter and a gasket in it (if yours is not reusable)

Hope this helps

Thank you that really did help.
now that we come to that, do you guys know what the pan bolts should be torqued up too?
