apparently it's also shared with the fwd xtrail from at least 2006, according to the service manual i found for the 2006 xtrail

Alot of that info is wrong.

The RE4F04B is not in the 97 altima, the RE4F04A is, which is the same tranny in the QG Sentra. The RE4F04B was in the 02+ altima. The RE4F04B Is in the sentra, but only up to the 04 maxima, after 04 it (maxima) got the RE4F04C, Which is the same tranny in the 04+ Quest, Maxima, Altima....... The difference is that it has 5 gears and the altima/maxima got the autostick.

^ I wasnt able to test it. I wasnt even able to run. But when i get tuned, ill be making a trip to the track.
