Has anyone gave this idea some thought? Taking out your 04-06 tranny and swapping in the 09 tranny. Since that tranny gearing is much shorter and is the ideal gear set. From looking at the tranny gear ratios chart. Would like to hear some thoughts about this because I plan to get a TSX and do that along with adding a wavetrac lsd in a 06.

 

this has been discussed. and from what I remember, the 09 tranny should be a direct swap.

now finding an 09 transmission could be fun.

 

why would you?

 

because the 1-2 shift is a PITA
