What you guys can tell me about that... any recomendations?

If you're going to track with the 7 speed auto, you should get the transmission oil cooler first. I would hate for you to have to go through the pains i went through. Usually the torque convertor seizes and or the flex plate breaks. Once that happens the transmission basically becomes inoperable and needs to be replaced.
There have been a few others who have experienced the same thing,
wstar and
megan370z also had to replace their transmissions. Even after adding the cooler, there is no gaurantee that the trans will last for a long time. I was able to get mine to last for 2 years and 10 track days after doing so.
Once i got my transmission fixed the last time (lol...i destroyed 4 transmissions) i decided that was enough and sold it, then bought a six speed 370z. Swapping the transmissions is harder than it looks and requires a lot of work to replace harnesses, the ecu and some other things to make the manual work in an automatic chassis. It was much easier and possibly cheaper to buy a used 370z and swap all my parts over.
