Ok so it looks like it was low on trans fluid. The shop added some more and it is back to normal. Thanks again everyone!

If they don't know how to fill the transmission, there is at least one thread on this site that tells how to do it without any special equipment from Nissan. There is a procedure in the FSM but it requires CONSULT (or some other way to get trans temp).

Do they know the proper refill procedure? Simply adding cold fluid to a hot or cold trans isn't always going to do the trick. The fluid need to be at the correct temperature when determining fill level. I can almost guarantee you that was the problem when they did it the first time.

I did find a few threads on here on how to do it but didn't trust myself to actually perform it. That is partly the reason why I had a shop do it.

The shop is regarded as one of the best (Z shops) here in Southern California. The reviews online were mainly positive. But I am disappointed that they botched this job. Not gonna lie. They installed a Quaife diff on my car last year and haven't had problems with it, so I'm a little undecided on what to do for future service(s).

Ok so I am at a loss now. I feel I should have never messed with this a this point. The car is doing the same thing now but only when cold. After I got it from the shop yesterday it sat in the garage for about 4 hours and then my Dad and I went for a drive. No issues then. I got in the car just now after it had been off for about 24hrs and it did it. Once it got up to temp it did not do it. What should I do?

Sounds like the tranny fluid is draining out of the valve body over a period of time. Then takes a while for the valve body to refill.

Thanks Rusty, will more fluid fix this then?

Sometimes yes. Sometimes no.

It is still a little low. When the tranny fluid is cold it will contract. When it warms up it expands. You are still just a touch low.

Were there any issues with the car before transmission fluid was replaced?

The shop will look at the car again tomorrow. Hopefully 3rd time is the charm. I’ll update you guys. Thanks again everyone.

No not at all. I only did it to try and prolong the life of my transmission as I didn’t think the fluid was “immune” to degrading.

Maybe just add another litre and see what happens.
But I heard that overfilling auto transmissions can cause issues as well.

You should only add cold fluid to a cold transmission. Then you have to start the car and idle it for a few minutes to bring the fluid up to temp. The transmission fluid should be 104F in order to verify the proper fill level. Note that you may have to back flush the AT cooler to remove any debris that might have built-up.

Just a quick update guys, the shop saw the car Saturday and let the car cool for about 30 min. They then proceeded to filling it some more and I can confirm the issue is no longer there after I tested it cold. Thank you all.
