30rh, A lock-up torque converter?

Can anyone tell me if this trans has a lock-up torque converter?

30rh - 1997-2002
* 3 speed automatic
* Used with 4 cyl models
* 23 spline output
* Ratios:

1st - 2.74
2nd - 1.54
3rd - 1.00
Rev - 2.20

I ask because this is what I have in the wife's '00 TJ.

In my '06 LJ, the trans (42rle) makes a slight scraping sound when the torque converter locks up. The '00 does not do this. The '06 is still under warranty and the dealer is telling me that the noise is normal. If the 30rh has a lock-up torque converter, than the "it's a Jeep thing" explanation does not really hold water, because they would both make the same sounds, right?

While the 30RH used with older 4-banger 2.5L engines does have a lockup torque converter, it's a totally different design from the 42RLE used in 2003 and newer TJs with six cylinder engines. I wouldn't count on them to make similar noises though I can't imagine a scraping noise at lockup being normal on a 42RLE.

Is your email address up to date in your JF Profile?
