I'm new to the forum and recently purchased a 2006 Infiniti G35. It has 64,500m and in excellent condition. My question is, should I have the tranny fluid changed? I've heard if you haven't changed it or had it serviced and it's not giving you any problems, then leave it alone. On the other hand, I've also heard to have it changed. What are your thoughts? Any advice would be greatly appreciated.

 

Change all the fluids. For trans, just a drain and fill, there's been debate on a "flush" causing problems. Also, safest bet is to take to a Nissan or Infiniti dealership, these require the use of "Genuine NISSAN Matic J ATF" fluid.

 

I think they suggest changing it at 30k. It really depends on how well the car was maintained.
Did the car come with a service history any documentation?
Here's a link to Infiniti's schedule & maintenance guide.
