yes it will work I had one in my comp G for a little while till it got the built trans from Triple Edge performance.
I gave Dave the GXP trans for a core when I picked it up
I am buying the trans on Saturday, so if you can share specifics on what I need to modify, I would really be in your debt. Thanks!!
