In spite of using stock Spitfire offerings, the shifter was shoved rearwards about a full inch. This caused problems with the shifter throw when going in to 2nd gear and especially 4th gear. The fix was to elongate the hole in the console, easy enough! Shifting from 3rd to 3rd overdrive and from 4th to
4th overdrive is just a flick of a switch away! The switch is located dead-center on top of the shift knob. It does not require the clutch to be depressed when shifting into, or out of, overdrive. It's pathetically easy - the ultimate in lazy!
