I have installed the Treco 1/10 Onroad TA04 conversion kit on my car, but I can't get the 3 speed to shift reliably. I can hear it kick in to 2 speed and the car gets a major speed boost, but the 3rd gear never comes. I am running a 14x2 motor, the rear is using the Treco locked straight axel, and the front is Treco's lightweight one way diff. Checked all the parts against the manual I think they are installed right; appreciate any thoughts.
Happy 1st April!
