I think mine makes the same noise you are referring to. I've never thought anything of it. I did 2 full pan drops and a new ZF filter/pan yesterday. No change in noise. Shifting is better, though.

I might be driving myself nuts with this noise. It actually seems louder inside the truck. |

i know there was a recall for something to do with the driveshaft on mine which is a 2011 n55.

This noise (or not) is also when stationary. It changes pitch along with the engine revs.

It's over-priced. No technical specifications. For all I know it's re-branded Pentosin or something of lesser quality.

If the noise is also when stationary then it may not be from the transmission. Does it changes in any way whether you're stationary in neutral or drive? |

It changes up and down along with engine rpms. Neutral or drive.

I was unable to find much info when searching for drive line noises, but I searched for N55 noises and came across a few people referencing the steering pump. I noticed my noise got louder the closer the rack was to a full lock, left or right, and much louder at full lock. I flushed out the old fluid with CHF 11S and the truck is considerably quieter. The fluid was filthy black, it was probably never changed.

Good to know! I plan on doing the same to my 4.8 with the adaptive drive. It's a BIG reservoir though. Probably holds 2 quarts alone. CHF 11S is spendy stuff.
How did you flush yours? |
