Purchasing 2002 double cab

looking into a couple different 02 double cabs and have some questions.

The one I'm looking into my buddy is selling its in good shape I haven't checked the frame yet or a couple other things. But he told me he just put in a new tranny a couple months ago now I know it's a new tranny but for some reason I'm nervous to purchase it. Should I be nervous or will it hold up? Any info would be helpful!!

 

where is the transmission from? rebuilt or just transplanted? is your buddy reliable or shady?

 

He's a good guy not shady. I'm not sure where it's from he just said its a new one.

 

if you trust him, then you should be ok... just stay on top of the maintenance...
