I can't seem to locate the trans drain plug on this vehicle. Do you think any harm would be done if I disconnect the return line, let it pump at idle until I see bubbles, then refill? I really don't want to drop the pan,as if I have a warranty claim, Nissan my use that as a reason to deny a claim.

Why would they deny your warranty claim? Honestly, the dealer is not even going to know if you dropped the pan.

If you're that worried, just have the dealer change the fluid.

How many miles do you have on that '09? I wouldn't worry too much about it unless you had 60k+. I have the same car and I am saving up for the Dealer to do it. That is a picky Transmission and that is about the ONLY thing I'd have the Stealership do the service for on that engine. JMHO.

Just did a transmission service on my sisters 09 altima. 90 worth in eneos cvt fluid 13qts. Dealership will charge around 160(drain and fill) to 250(machine). I called them becuz I was skeptical at doing it first. I think a pan drop would be your best bet.

See if you can find a torque spec for EVERY thing you have to tighten back up. And be sure to use a good method to measure the torque you apply. These modern parts are built with so little excess material that is is real easy to strip them. Rockwell makes a special tool to tighten all bolts on transmissions including the pan. This machine even takes into account if there is anything fouling the thread such as dirt or shavings left over from manufacturing. Before this tool was used there was a high rate of rejects during manufacturing because threads would get stripped from over-torquing them.

If you strip a thread you are opening up a who new can of problems. You will have to go up to a larger size or healy-coil it.

I think your right, Is the Enos the same color as the NS2?

BTW the car has 30k on it. It was a rental that I bought for my daughter. That's why I am changing it now.

A single drain/refill every ~15k is good maintenance for a CVT.

And, since its a rental, I'd definitely consider it soon.

Is a pan drop necessary? My understanding is that there IS a drain plug.

My 2008 will hit 30K in December and I was planning to do a single drain/fill at that time and continue to do so every 30K from there on out.

I had a 07 Altima. I traded it in before it needed a CVT service. Here is a DIY CVT change from my old forum I use to hang out on.

I changed the CVT fluid on my friend's 2008 Altima 2.5 SL. It was very easy, and there was definitely a drain plug at the bottom of the CVT pan. There is no need to remove the pan.

Basically, we drained the fluid, refilled with the appropriate Redline CVT fluid, and then disconnected the fluid line leading to the radiator to help push the old fluid out of the torque converter. We idled the car for 30 seconds until the fluid started to sputter slightly, and then refilled with the proper amount of fluid. After a good drive, we checked the level according to the FSM procedure, and all was good.

Honestly, the colour of the Nissan NS2 fluid that came out of the CVT was pitch black. Nissan would never know the difference if you used a different fluid. My friend only had 40,000 miles, and it was completely black. The Redline fluid feels silky smooth. Way better than the stock fluid.

They most definitely would know.

The NS-2 fluid has a green-ish tint to it. It also, most likely, has a chemical identifier. In the event of a CVT failure, Nissan will pull a fluid sample and analyze it to ensure that the NS-2 fluid was used. So if your friend experiences a failure under the newly extended 10/120,000 mile warranty, he's screwed.

Really, have you seen Nissan analyzing fluid?

I wonder if all of that is necessary? I've read elsewhere that Nissan's standard procedure on the CVTs is to simply drain and fill twice. I have the service instructions for a 2007 Sentra and that's what it instructs.

On the topic of fluid, this sounds like the Honda Z1 debate. Personally, I'm not going to take any chances with the 10-year / 120,000-mile warranty and am going to stick with NS-2.
