Hey guys maybe you all can help me out, I have a inconsitant rattle the comes out i think from my tranny(auto) at 2100 and 25-2600 rpms and its geting on my nerves. It sarted when i decided to change my transmition fluid and filter. I took all the screws out in one order and put them back in the same order but the last screw wouldnt go in and stay it would just fall out and upon looking at the screw inoticed that it had a smooth shaft and it wasnt threaded all the way up like the others were, it was the same length as a few but when i removed some of the other long ones it wouldnt catch at all so i put it in and it went all the way in so it looked like it was suposed to so i sealed it up put the fluid in and started driving. and imediately the rattle happend . i knew it was the screw hitting the pan so i let it go untill recently i decided to just take the thing out or try to get it tightend down but it wouldnt go in and stay so i just took it out and sealed it up again and the dang sound came back . just after i said to myself i fixed it . funny right well i want to know what you guys think i should do. I really want to fix this it seemed so simple. How do i make it stop rattling, or could it be something else and just a coinceidence that i was putting my new filter in the day it started to rattle. Oh and everything is pretty much stock exhaust and everyting stock. Help Please.

Ok, I think everyone with an auto transmission has done this at one time or another (me included).
The transmission filter is kind of a pain to change out because you must remove the valve body to do so.
The problem is one bolt goes all the way through the filter and the valve body and connects with a nut on the opposite side. When you removed the filter this tiny nut falls off and you really don’t notice it until its time to bolt the new filter on and you’re left with one bolt that don’t screw in.
We all agree it was dumb of Nissan to put this one nut on the wrong side of the valve body. I’ve heard some guys simply weld the nut to the VB for a permanent fix.
My real beef is with the parts stores who sell these filters w/out instructions or proper advice. I’ve had many a heated argument about this particular subject. Seems nobody believes me when I tell them they have to remove the VB in order to change the damn filter.
Anyway, I’d recommend you check the magnets on the bottom of your transmission pan for the nut. Then remove the valve body and finish the job you started to begin with.
As for the rattle… it could be the nut rattling around in your transmission or it could be something else.
thought about taking the valve body out then looked at it and decided screw it, took the bolt out and put somewhere in case i ever did take out the valve body.
been running the car about 6-7 months without a problem and if you search a few others did the same thing, i have no leaks or any problems that i know of, to me i felt it wasn't worth taking out the part, and possibly causing more problems since i don't know crap about the trans
Well guys i found the rattle after diging deeper and i decided to remove the heat shield on the exhaust pipe both of them and that fixed it. and as for the trany info thanks alot for your replys, I did not know about the nut. ill look for it nextime i open it up and yes it was dumb for them to put that nut where we cant hold it and put the screw in . i wonder if a trnsmission shop knew about the nut and didnt tell me cause i did stop and ask someone about it and he wanted to charge me the same amount as a heart transplant. THANKS GUYS.

How difficult it is to take the valve body off? Any advice on doing so?
Also, if I leave the bolt out, won't the nut get into / under some moving part and destroy the whole tranny?
Thanks,
Leon

I did the same thing today - removed all the bolts and can put one back. From your experience, is that safe to drive the car with that nut wandering inside of the tranny?

Fortunate for me, magnets inside the bottom of my transmission pan caught the loose nut. I suppose it could have cause a problem but I also noticed most the valve inlets on our VB seem to be smaller than the nut. I estimate the probability of this nut actually causing any damage is quite low, but there is always a chance.
Best case scenario just locate the nut and bolt and remove them from the transmission case.
Oh, and keep an eye out for a small washer too (at least I think there was a washer).
thank you for the post and the message you sent to me privetly. So, there is no 100% guarantee that the nut won't get into the tranny or the valve body and cause thouble.
I am seriosly thinking of taking the valve body off and putting the bolt where it belongs to. Do I get it right that all I have to do is to unscrew 15 boltsand I'm done? Nothing to worry about? No catch?
Thanks,
Leon

Simply take your time (make a day of it) just work slowly and efficiently. It's easer then you may think.
Before taking on this procedure you should...
- print out all pages and pictures from the service manual
- take a piece of cardboard and sketch a picture of the VB. Then make holes for each bolt you will remove.
- unplug any electrical connections to the VB.
- have a clean table standing by where once the VB is removed you can attach your filter properly.
- Avoid dirt at all costs. Keep the Valve Body as clean as possible.
Follow these steps and this job should only take about an hour or two.
