Ok so before I changed my gearbox over I got a friend mechanic to plug the diagnosis machine he has, but he only had a 200zx code reader which did read all the gearbox info and the other engine codes what I'm wondering here is will this be a reliable source of data? As in can it give me incorrect readings if I were to run other diagnostic in the future?

Hi Leeroy quick responce is in search box type self diagnostic autobox.

 

Jeff at Zworld i think put it up.

 

its a start, hope it gives u some idea.
