Thanks. I wasn't able to release the catch on my cvt dipstick so i couldn't verify the coor but other research indicates, as you stated, green - not red. Not sure where the red is coming from. Chalk it up to PFM.

Use a small flat head, push it in while pulling up and the dipstick should come out. I'm guessing that the green and oil mixture might give alittle red, who knows have you checked your coolant to see if that is not red?

The only way transmission fluid could ever get "into" an engine is if the trans had a vacuum modulator that failed and trans fluid was sucked into the intake manifold. Even in those cases, the ATF would not contaminate the engine oil but would create a large amount of smoke out of the exhaust as it was burned. Vacuum modulators have not been used on Nissan trannies for well over a decade and are not used on CVT trannies. While it's possible for coolant and transmission fluid to get cross-contaminated (if the radiator's integral cooler tube failed), there is no possible mechanical failure that would allow engine oil and ATF to cross-contaminate. If a torque converter or front seal leaked on an auto trans, the ATF would leak out the bottom of the trans bellhouse. It would be impossible for the ATF to push itself through the rear crank seal of the engine or through the oil pan gasket. If diff seals failed, it would cause an external ATF leak that would get sprayed around by the rotation of the axle or just leak to the ground.

If it is a certainty that no one has put ATF, red P/S fluid or another additive or dye into the engine oil, then I would suspect that perhaps the reddish appearance is just that the oil is slightly dirty and appears to be a reddish color on the dipstick or rag? As mentioned, the CVT fluid is green, so it's not that.

As far as the grinding noise, is this just a one time noise when you first start out or a constant thing? If it's a one time noise, it could be the ABS system self-check. If it's a constant thing, I would have the dealer check it out.

Thanks for the reply. I think you may be right about the red being from getting a bit dirty.
The noise happens during acceleration and never when braking. It never happens when the transmission is not engaged.

I guess i'll have to wait till i get some more definitive, trackable attributes to continue the search.

I changed my NS-2 CVT fluid on my 2009 Altima at 50,000 miles. I used a cheap vacuum hand pump from autozone to suck the fluid out of the transmission. The fluid was still very green at first but quickly turned a dark brown color as I evacuated more out.
Could it be your fluid was just dirty from normal use? By the way, I ended up changing all of the fluid myself by replacing the 5 quarts of old fluid with newNS-2 then disconnecting the return line from the CVT transmission cooler and running the car then stopping the engine in one quart increments. This is a two person job as the return line will evacuate a quart of fluid in about 7-8 seconds. Afterwards, the transmission was much smoother. I plan to do it again at 100,000 miles. currently, I'm at 87,000.

CVT FLUID

Changing

1.Warm up CVT fluid by driving the vehicle for 10 minutes.





-arrow indicates: Vehicle front
- Radiator (2)
- CVT fluid cooler hose (inlet side) (3)
- Transaxle assembly (4)
2.Drain CVT fluid from CVT fluid cooler hose (outlet side) (1) and refill with new CVT fluid at CVT fluid charging pipe with the engine running at idle speed.
3.Refill until new CVT fluid comes out from CVT fluid cooler hose (outlet side) (1).
About 30 to 50% extra fluid will be required for this procedure.

CVT fluid: CV2
Fluid capacity: 7-3/4 qts. (7.3L)

CAUTION:
- Use only Genuine NISSAN CVT Fluid NS-2. Do not mix with other fluid.
- Using CVT fluid other than Genuine NISSAN CVT Fluid NS-2 will deteriorate in driveability and
CVT durability, and may damage the CVT, which is not covered by the warranty.
- When filling CVT fluid, take care not to scatter heat generating parts such as exhaust.
- Delete CVT fluid deterioration date with CONSULT after changing CVT fluid.

4.Check fluid level and condition

Gary100,

What is the outcome of your delimma? Is your motor oil still red?

NissanAltima01,

Are you still of the opinion "That service manager sounds like he needs a new job"?

Inquiring minds want to know.
