I have been dealing with these "level" fluid procedures since 2013.
Jettas, Camaro, Mustang, all have the; run the car idle at X temp, till fluid stops coming out...
I have not ONCE, followed the procedure. I drain it, measure, and put in what came out.
You really can't go wrong with measuring and putting in what came out, unless you're
leaking fluid somewhere.
So, If there is a spec, and what I took out is less than what the service manual says it should
be, then I put in what the manual calls for. If, in the end it only takes 4-liters, then that's
all you put in from there on out. Drain it, cap it, pour the 4-liters in and be done with it.
The service manual tells you what it takes, from bone dry, to just a pan drop.
Overfilling? It only becomes an issue when you go too far. A pint, or two, will not hurt
anything. Half to a full quart, can cause those issues, foaming and so forth.
If you added a cooler, then you need to take that into consideration. I plan on adding the
external cooling kit for mine as soon as possible. However, the 4-core front mount Aux
cooler, and hoses can't hold more than a few pints:
The 3rd gen Rogue CVT was changed, the belt does not bathe in the trans oil
anymore. They changed it so that part of the primary pulley is not bathing in the
The picture doesn't do justice. They make it appear that there is just less fluid in the 3rd gen version trans.
All that they really had to do was change the tilt. Here though, they look the same, just the one on the
right, the NEWER one, has less fluid in it, but that is not the case.
I have never had a transmission fail on me, doing it my way. So, it can't be all that prudent, to fill it,
idle it to X degrees, pull the plug and wait for fluid to stop dripping. Never done it that way, ever...
HEAT is the #1 killer of automatic transmissions.
