Default Tranny Problem

My a4 is clunking every few seconds when I put it into Drive or Reverse.
Neutral is fine. I just installed some Long Tube Headers.

Would it be the 02 sensors adjusting. I am planning a tune up. I'm just confused.
Any help would be great

Try pulling your codes and see if anything shows up there. You need to figure out if the tranny is causing this or the engine. When you installed the headers, were you careful of the tranny wires not getting onto anything hot? O2 wires same thing?

Clunking if its coming for the transmission its loose torque converter bolts. I dont think it has nothing to do with your headers. Pull the rubber access panel off and check all three bolts, or have a shop check it out for you.

Pulled codes. Nothing came up. I also made absolutely sure no wires were near exhaust, even covered 02 wires in heat tape.

Looks like I have a tranny seal leak. Will check the torque bolts.

Thanks for advice

How did you arrive at this determination? There are numerous drive line components that could exhibit these symptoms.

Could also be the torque tube couplers.

Your absolutely right, but if it was another component other than the torque converter bolts he would be complaining about a lot of vibration, or really weird squeaky noises. We'll see when he figures it out.

Hopefully he can diagnose if the noise is coming from the rear, midsection, or front of the drive train.

Its just going to be hard for him to diagnose at home because putting the car in gear and going under it itsn't the brightest thing to do.

Your absolutely right. That's why I'm sending it to a tranny shop next week. I did notice a oil leak on side of transaxle.

Just curious how many miles do you have on it? I had 120,000 on my c5 before the first tranny rebuild and I had no leaks. I hope the people you take it to are trustworthy and didn't purposely overfill your tranny causing a leak. Down here in Miami shops do all sorts of things to keep you coming back.

Just clocked 12,000. Had to pull transaxle out 3 years ago to replace fuel tank leak. Did an oil fill then and haven't had a problem since now.

Dropping the fuel tanks does not require pulling the transmission or rear axle.

Only the newer 2003 -2004's I think you have to drop drive line, but not on the earlier one's

Bummer that really sucks. Looks like Gm really wanted to score the extra work when they came up with that one.

If it started immediately after the Header Install I would suspect something with the header install bumping somewhere.

What did they change in the '03s and 04's? Isn't there still a piece of rad hose with hose clamps connecting the two tanks?

I belive they moved some sensors to the top of the tank. No personal experience with them myself, only what I have read.

Yes, there is a cross-over up there and they have had some leakage problems. Not sure if it was self induced or an actual part failure.
