A little background here.

At approximately 200,000 miles, I did a full clutch replacement, replacing throw out bearing and flywheel as well at that time.

At 219,00, the original engine was burning approximately two quarts of oil every few weeks and was misfiring. The car was parked for about a year until I was able to source a new engine. A few weeks ago, I finished replacing the engine with a 3.5 from a Maxima that had 65,000 miles.

The car ran fine for about two weeks off/on while I was in the process of getting it inspected and chasing some power steering leaks. However, beginning last week, I began to notice a squealing sound when the car was in neutral with the clutch pedal fully released. When the pedal is pressed down even slightly, the noise goes away. This did not happen at any point before the engine replacement and did not happen even immediately after the engine replacement.
I can also slightly hear this noise at times when shifting as soon as the pedal is released for about a second, but it goes away as rpm's increase.

Here is a video of the sound: https://www.youtube.com/watch?v=PlrXfbFgm7E

Now, I have also noticed that it is occasionally difficult to shift out of gear, but I have only noticed this when downshifting. No issue shifting up, but if I am engine braking and trying to shift down from let's say fifth to fourth, the shifter becomes much harder to push out of gear. If I release the clutch pedal and push it down again, most of the time it comes out of gear just fine. If I force it when there is some resistance, I can feel like a slight "pop" in the pedal. Otherwise, the car shifts and drives just fine.

Any ideas here? I am not a transmission/clutch guy. I had help when the clutch was replaced and do not have a ton of experience with either, so I do not really know what exactly the issue would be. if the transmission needs to come back out, other than obvious signs, I am not really sure what I need to be looking for so I would like to get some ideas before getting to that point if I can.

When the engine was swapped, I did drain and refill the transmission with Redline 75w-85. I checked to make sure it was still full and there are no leaks. I am not abusive to the clutch ether the original lasted to about 200,000. I have a long drive back and forth to work everyday that is mostly highway so I take it pretty easy.

Please help!

Thanks
Justin

From your description it sounds like a release bearing or throw out bearing as well as needing a clutch adjustment. But because of this it may have worn the pressure plate as well not giving you good clutch when you shift down. If you got a cheap bearing or one from china then I would kind of think that is your problem. But it will have to come apart again. Chart shows what Nissan recommends for better shift quality after transmission repair/replacement but if you put a pint of synthetic oil in it makes them shift better as well.

The video really helps so thanks for that :)

Thanks. So you think it sounds like a throw out bearing/clutch issue and not transmission issue? The video link I posted is from my actual car if that helps.

The replacement bearing was a part of an LuK Replacement Clutch kit. I thought LuK was supposed to be decent stuff. I was able to get a really good deal on another clutch kit online today actually, so I have new parts on the way. The deal was too good to pass up so I figured I'd buy it even if I didn't need the parts.

Redline 75w-85 is full synthetic and is what is recommended by most of the Altima guys. What kind of synthetic oil are you referring to?

Was just saying the adding synthetic but if you already have it in then use it it really makes a transmission shift smooth I made a mistake on this sorry. It may be the pilot bearing /bushing that goes into the end of crankshaft. As the noise is when it is released. Does it make it in other gears as well or just in neutral? I kind of doubt it is a transmission bearing, as those would make a constant noise through all gears and it would not be a squeal it would be more of a grumble/whine type noise.
