I am constantly working in my garage on my cars and such. Anyway I have a friend who's sister knows a couple that needs some help with their suv. (its a chevy) hahaha. Anyway this chevy needs a transmission. I told them I would put a junk yard one in for half price and they like that option. How do I make sure I dont get screwed? Ask for half up front? do you guys do anything like that? I would like to get some money to at least buy the transmission from the junk yard. The junk yard offers 60 day warranty on the trans.
