Overfill Transmission

[mfas12]

Hi everyone,

I just did a drain and refill on my 99.5 QX4. The atf fluid seemed to be slightly overfilled from the factory (a bit above the max line on the dipstick) as that's how I found it and it's been in the family since new so I know no one did a atf fluid change before. I measured exactly how much came out and replenished exactly the same amount and was wondering if I should siphon out a little to get it to the correct level on the dipstick or stick to exactly the same amount I took out?

mac,if when just warmed up & like 3 mi drive your even 1/4 " above the high hot mark - no problem. Now when , from there you "push it" driving hard on hot afternoon the level MAY come up another 1/8-1/4" -that happens when run'in HOT. No more than this scnario or you may consider purging some - especially if you think there is odd shifting behavior afterwards.

Transmission fluid should be checked while the car is running and is warm - just thought I'd mention that since it will look fuller if the fluid is in the sump, not swirling around the unit.

I think if it had been running overfilled since 99, the transmission police would have come knocking already. I wouldn't worry if what you drained and what you filled was equal (at the same temp*)

I must also declare that although I consider myself a little handy, I find it hard to read Nissan trans dipsticks and defer to the dealer to monitor the trans temperature with their Consult tool and have the fluid at the correct level.

As mac alluded to in the post above, transmission fluid is very temperature-sensitive.
Since they don't even bother to give us a dipstick anymore, here's a quick read if you're bored
