First Gear Rattle Around 2,600 rpm (auto trans)

[JKCutler3]

So this is annoying... I'm driving the other day and start to hear a fairly consistent rattle right around the time the car shifts into second gear. It is very intermittent, and does not occur if I'm accelerating aggressively. This only occurs when accelerating moderately and it only happens in first gear.

Trying to replicate the noise is pretty difficult, but I figured out if I put my trans into Sport mode and hold her steady in first gear holding around 1,200 RPM then moderately accelerate the noise occurs between 2,200 and 2,800 RPMs. Once I hear it, I let off before shifting into second, bring the RPMs back down and can accelerate moderately to hear the noise again. I do not hear it outside of first gear and I mostly hear it after accepting from stop lights.

If I get on it aggressively, I hear no noise.

Its worth mentioning, the tranny is shifting great, car runs and idles great as well. I did just have a new snub mount put in about 1,000 miles ago and did not replace the worn motor mounts.

I'm stumped....

I get a distinct rattle around 2200 RPM.. I've replaced and checked a lot of parts and cannot seem to track down what's causing the rattle.

This thread has a solid discussion within it and it should get your hunt started in the right direction:

I have the same rattle on my auto 1.8T. Im going to check the dp/cat area a little better and check for any loose bolts.

Let me know what you find. Going to get under there and see if I can find a bolt or something loose.

Just weird, it happens in 1st/2nd around 2k. I feel like if it was the cat it would happen more often.

No solutions. Sound now comes and goes.
