Quick question, my son has the Telluride and we started stripping out spur gears lately. I finally decided to pull out the motor as I could not get the mesh set properly. It looks like the motor shaft is moving just enough to not allow a proper mesh to be set. I see alot of post about the 12t motor as not being a good fit for this car and most seem to recommend the emax motor. Can I use the same mount, spur gear, pinion gear and batteries. Or does all of this need to be changed. If so, what are the recommendations?
