do you still have to engage it manually?
remember reading about having to push a button, and you could split gears.



A control box and all electrical harnesses come with the GV. It’s, plug and play. You can select to auto engage overdrive (it engages at 45mph and disengages when you stop) or you can select manual and manually engage the overdrive. I installed a foot switch (a head light dimmer switch supplied with the GV) on the floor to manually select overdrive. It works great.
