42LE..Rebuild,or not?
 

Hi guys, Just bought a 2000 300M with a "Transmission leak". Got it cheap enough,but the transmission has engine coolant in it.I suspect Radiator cooling line rupture.
I can have a local friend rebuild it,or my other option is put a "used" one in the car.The used one is from another friend that pulled it from an 02 300M.He said it worked fine,and had around 90,000 miles on it.I can get it for 300.00...Need some advice here please:D
