I just took an E revo 2.0 trans and fitted it into my Maxx based basher (T maxx chassis/mono block/FLM bulks with 1/8 diffs). The trans fit my RC so it should fit any E maxx. You have to remove the revo top shaft from the trans and replace it with a brushless E maxx top shaft. You will need to cut the back half off the E maxx top shaft to match the E revo top shaft. Once you have the two in your hand you will see what needs to be done. This needs to be done so you can reuse your existing E maxx slipper/spur what ever your running. Motor plate...The holes in the motor plate will also need some tweaking. Looking at the front of the trans the bottom left mounting screw is fine, the top one will need to be slotted, the next one is fine and the bottom right will need an entirely new hole drilled.
