7 Speed Auto Trans Fluid Change
What is the trans fluid change interval for the Auto 7 speed transmission?
I read that the A7 requires special tool to change the fluid. I have also read some posts that the fluid is lifetime and that's the reason Nissan didn't specify the change interval. Also read that some dealers don't know about the special procedures. Thoughts? Thanks. |
They claim you never need to change it but I don't get it. My car has 27,000 and I've changed it twice.

There is no interval for the 7AT fluid. According to Nissan, that fluid is maintenance-free.
A few people on the forum have had it done by their dealer. Sounds like you read about the dealer that messed up cause they didn't know what they were doing. Unless you're having trouble with your transmission, its probably not worth messing with it. |

Unless you are tracking it or are coming up on 100K, I wouldn't bother just yet.
If you decide you should change it, there is a fairly specific procedure -- I believe it is detailed in the FSM, which can be downloaded from here --> http://www.the370z.com/nissan-370z-o...-download.html |

you could probably get away with an IR thermometer pointed at the sump, just account for a few degrees difference and you should be sweet. that's what i'd do but what you do is up to you :)

I don't track the car and I don't mind paying the $200 to change it, but I am worry that they might screw it up in the process such as introducing contaminants into the trans. I am sorry, but I don't have much faith with the dealer mechanics as they all try to rush through as many jobs as possible so they'd get paid for 20 hours in a 8 hour day. Thank you all your responses. |
My AT was giving me some serious issues. I got it changed and all the problems went away. YMMV
|
OP, I think you're smart not to trust the dealer mechanics with that job. If you don't track the car, I would worry about it unless it starts giving you problems or you hit 100K miles and just really want to change it.

You may also get an occasional "clunky" downshift for similar reasons -- Nissan may have further "refined" the tune on the newer MY's. Additionally, the ECU has a sort of "trim" table for shift points based on your driving patterns when in M mode which can make the car shift a bit oddly in regular auto for a bit. I think if it seems ok when warmed up, you are probably fine, and if you ever get a tune, you can have the torque tables adjusted for much faster, firmer shifts :D If it continues to act clunky, it might be worth seeing if there's a new-ish OEM reflash to adjust the shift characteristics -- there very well may be. |
I've had two tranny flush and refills at my dealer, cost 189$ each time. Roughly 30k between flush and fill.
