G3R - What trans ?????

Hello

First off let me say that I have enjoyed soaking up all kinds of advice and knowledge since I've been on this forum.

My Q's are

I bought a new E-Revo and a new Gorilla Maxx G3R kit, assembly went fine, now I need a transmission.

1st - What was the trans that Gorilla Maxx designed this thing for, from what i have read you need to modify the stock e-revo trans??

2nd - The Trans from Fast Lane is for the E-Maxx which is fine but then I read that you must use a "mod output shaft" not sure what this is and there is nothing on there website called mod output

And then what about drive shafts sounds like those need to be swapped out as well


Just want a solid trans, price doesn't matter but cant seem to find the clear solution with part #'s and manufacture names of each peace.

Sorry for the long post just getting anxious to get this thing moving.
