Hey everyone...

Planning on installing a DC5R LSD (oem) into my 06 TSX this weekend. The friend that I bought the LSD from had mentioned swapping the speed gear (not the final drive, I already know to swap that) that's inbetween the diff. and the diff. bearing. Are they all the same? There is no part number for that piece that I can find.

Can I just use the one on the LSD already? Or do I need to use the TSX one? Thanks!

As far as I know, they should be the same. But do not quote me on that.

You can put it in and see if the gear rotates the speed sensor.

That makes sense. I think it will be a bit more obvious when the case is open, but the friend I bought the LSD from needs that gear for his setup apparently.

You don't need the speedo gear. The TSX uses a speed sensor that reads off the mainshaft.

So I should remove it? Doesn't the bearing press against it? Safer to leave in as a spacer for proper fitment?

Thanks for the help.

Hey Jay, your TSX doesnt use that gear to read speed. TSX uses the mainshaft. ;) Get that sucker installed already!

You can see in this picture where the ring would be installed.

Thanks all. LSD is installed and speed gear is en route.

And on that note, the TSX should have one of these from the factory.

The TSX speed sensor is picked up off the side of the 3ed gear.

Running 2 weeks now with a 06 civic Si gear set (PNN4) in my TSX case with the Honda LSD. Using dakota SGI-5 box to fix the speed signal.
