New transmission, now a rattle! (SOLVED)

Something not working right?

Ok so most already know that yesterday I put a new tranny in. Today I finished up my exhaust with a dynomax superturbo (by the way it sounds awsome).
Well while sitting at a stoplight with the music off I heard a rattle from what seemed to be the center console area. I started by removing all the change and stuff from the console and the noise was still there. So I climbed under there and it originally sounded like it was coming from the exhaust hangers, lubed those up and kept listening. Then I noticed it was coming from the transmount/transfercase area. I checked the fluid in the case and it is a little low, but dealership is closed today. Does anyone have any reccomendations, I know I havent got to try everything yet, but im about to leave the wife with the truck for a month, and dont want it breaking on her while im away. I would hate for it to break and her go pay to get it fixed, thinking she broke it and not wanting me to find out!

That really leaves it pretty open. What are the circumstances when it rattles? Only at a certain speed, certain gear, certain trans case setting? Too many potential things to list them all here. Hopefully it's just a trans mount or something. Didn't you just replace the entire transmission?

Yes, last night to be exact! It only does it while sitting still, Park, Drive, or Neutral. Once it starts rolling it goes away. I have yet to try putting it in anything other than 2HI as my disconnect is broken anyways.

If it only happens while sitting still, then it probably isn't your TC. Anything past the torque converter won't be spinning. If it's a bearing or connection somewhere, it could be there. Otherwise it's probably a rattle in a linkage somewhere, etc.

I agree, its more of a vibration rattle, than a spinning rattle, if that makes any sense. I dont believe its anything internal. Ill have to wait to get back on a lift and try to figure it out. I checked all the bolts, they are all torqued. All this trouble just keeps pushing my lift more and more out of reach! But for now I'm happy to have 4 gears again!

FOUND IT!!!! I had a little bracket on top of my transfer-case that the wire plug hooks on to bent up a little to much and it was just rubbing the underside of the body! :wallbash: Man am I embarrassed!

Its so relieving, and not that it was just annoying the crap out of me, I was actually nervous that something may have been messed up! Therefore I was afraid to drive further than the 4 miles to work. All other trips were in the 95 Saturn! I hate driving that thing, I just feel so cramped up in it!
