The kick down switch on a TH 400 transmission serves to downshift the transmission to a lower gear when the driver accelerates quickly. It engages when the throttle is pressed beyond a certain point, allowing for increased power and responsiveness, especially during overtaking or merging. This feature helps improve performance by providing quicker acceleration while maintaining optimal engine RPMs.

It can be done, but takes a little work. The crossmember will also have to change location which may require drilling a few holes in the frame.
