i got the new tranny from courtesy nissan and it was shipped crappy as hell. the plastic cap plugging the speed sensor broke (among a few other things) and it all leaked out. i couldnt really tell what the fluid was since it was all soaked up by the box. there was some residue on the bag, but it was clear and didnt seem like tranny fluid to me since it didnt smell like crap. its had mt-90 in it since i first swapped it in about a year back. is it that important?
