[W126 Coupe] Passing Gear

[Steve Nervig]

Ernie, here are a couple of pages from the Service Manual that may help you. 

Also, have you lubricated all of your accelerator linkages?

I had never noticed them before but as you can see in the photo, I should be able to down shift up to speeds of approximately 110 mph.  I only know that the switch seems to move in and out freely with moderate pressure from my hand.  Trying to see with my old eyes  where the switch connects to is not that easy; any idea where the other end of the switch connects to?

>> Ernie, if your speedometer is anything like mine (W124), it should show the maximum shift point of all gears on it. There are little tick marks for each gear. See <http://web.mac.com/dakota/Trips/Day9.html#14>. See the tick marks between the MPH scale and the KPH scale? If you are somewhat below the 3rd gear tick mark in 4th gear (say 10-15mph below), and you floor it, it should downshift to 3rd.
