Sport/economy mode gearbox switch.
I have a problem with my '88 560sec. The sport/economy mode switch on the gearbox moves but doesn't change modes. It is stuck in sport mode, which is fine for those quick starts from traffic lights, but doesn't help the smooth starts or fuel consumption - (at $4.50 a gallon in the UK it's bit of an issue).
I'm not sure where to start looking.
Any help would be greatly appreciated.
Also, does the sport mode only do the first gear start, or does it also delay changing gear untill you hit higher revs??
