TRIUMPH TRIVIA

One nice thing about retirement is that I have a bit more time to attend to detail and minutiae. This morning, I was watching a video produced by the TR register of Belgium. This was dated 2003 and pertained to the 50th anniversary of the Jabbeke Speed Trials run by the late Ken Richardson in a TR2. Several sidescreen TR's formed a procession to the spot where Ken made history. I noticed something unusual about one of the TR3's driven by a pretty Belgian lady. In one of the cockpit close-ups I saw this unusual lever at the base of the normal gearbox remote control. What was this unusual gizmo? Here is a still frame from the video. I apologize for the poor quality of the screen capture.

Does anyone know the answer? What is this thing? :smile:

Overdrive selector. What do I win?
 
Dang it, Andy beat me again.
 
Andy - that isn't fair. I do know where you got the answer.

Randy - you get a big grin and a cold Victory brew next time you visit.

Yes, you are both correct. I think this is just too cool! No blinkin' solenoid to worry about. :yesnod:

Of course it's always possible that Andy knew before the other thread ... I did, although I had never seen those pictures. Thanks to both of you for posting them.

Personally, I'll stick with the switch.
 
I have one of those lever setups down in my basement somewhere. I always wondered what it would look like on the transmission.
 
Do these manual actuation levers have a provision to prevent engagement in reverse? Maybe there is a mechanical tie-in to the position of the 4-speed shifter that drops the O/D out?
 
There appears to be something sticking out & forward on the right side of the unit. If pulling the dingus down disengages (hard to be sure with that Rube Goldberg linkage) then perhaps shifting into reverse causes the stick to push that thing and disengage the overdrive.

Does not address 1st of course, but reverse is the true third rail for ODs.
 
Looks like the "dingus" to the right acts as a lockout, preventing the gear lever from being moved to reverse when the OD is engaged.

It doesn't address first, but the OD likely just won't engage in first. The oil pressure is determined by the speed of the gearbox output shaft. The lower the road speed, the slower the pump is operating. On my rig, engagement time for OD in 2nd is pretty long. I don't think it would ever make it in first.

That indicates a problem of some sort. Yes, the pump output is pretty low at low speeds, but that is why the A-type has that accumulator. The accumulator should be full by the time you get to a reasonable speed in 2nd gear (since it has been accumulating since standstill), which should give an instantaneous shift.

I forget who it was, but there was someone at the VTR hill climb a few years back running an A-type that was modified to allow OD in 1st. I assume he had also turned the pressure way up, so it could handle the torque.
