Hmm, if Reverse is up to the right it is possible that1st gear is up to the right, next to Reverse, and 5th is the up to the left (F in your diagram). That means the tower lever is acting backwards from what should be happening.

Check that when the shifter is moved laterally to the left, the tower lever cable is pulling to move the gear actuator upward (the top most position should be Reverse). Check the other direction too for the cable pushing the tower lever to move the gear actuator downward.

100%, just like your picture Ross. I just rechecked the pattern. It easily goes backwards, if I ever so slightly easy out of Reverse and go left and up it goes forward easily, but I have to reverse and feather the clutch to get it to pull forward when in the current 5th gear according to your picture.
This explains why it kept stalling

Is it the way that the F35 vs the F40 shift mechanism works on top of the transmission?
- or I messed something up rebuilding the trans?
- or I messed up building the shifter somehow, I'm not sure that this is possible.

Does anyone see a way to reverse the direction of the cable on the right side of the shifter? Like changing it to the front of that arm? Would putting it on the other side of the pivot allow for reversal of the shift pattern?

You'll get it, it only goes together two ways and one is wrong. The wang thang cable goes to the shifter lever and the plunger cable goes to the L shaped doo-hickey.
PS: If you swap both cables on both ends you will be back to square one. I know, I tried that once(that I will admit to), D'OH!o_O

Ok, I looked at my custom RSX position it appears to be working correctly. Let me explain the function in the pictures of the lateral lever. In this first picture is the fixed pivot for the lateral lever (has the black spring around it). In the second picture is the movement pin attached to the bottom of the shifter and connectedto the 'L' of the lateral lever (has the black ring around it). Moving the shifter left raises this pin, to the right lowers this pin.

The hex head bolt is where the shifter cable connects. Moving the shifter left (pin moves up) and the bolt moves forward which pulls on the cable.

Moving the shifter right (pin moves down) and the bolt moves rearward and pushes on the cable.

The lateral motion lever is connected to the tower on the transmission, via the shift cable. Here is a picture with shifter in the middle position.

This is the motion needed by the DF shifter to achieve the correct gear pattern to have Reverse furthest left and forward, next to 1st gear. Tie this information to the explanation of how the transmission levers move to select gears for the pull and push motion on the cables (a pull at the shifter is a pull at the transmission).

Compare this with the motion on the DF shifter.

OR you could just have a built-in anti-theft device with a mirror image shift pattern like in the photo from Ross. It would take a bit to get used to, but no one will driving your Goblin away! :p

Looks like I'm driving a righthand drive pattern for a while. I'll work on getting that rsx setup ready.

Never too early to start searching parts. I like the black. This looks like yours, DS, no?

Yep, that's the one. Know that I had to modify the base to better fit the tunnel cover and reduce intrusion into the footwell area. Also, the mechanical 'well' where the shifter lever ball resides is open to the elements, so made a mini shifter boot to enclose this area. The overview for this is in my build log. We can IM for the finer details.

It really doesn't look like there is room to put the cable that controls left and right movement on the shifter anywhere else on the trans shifting mechanism. The mechanism on the transmission is pretty compact as it sits, but Im no engineer.

What is that counterweights job? The big axe looking portion where the left cable snaps onto. Does that get cut off on an F35 during installation in a goblin?

Well if you can't flip the transmission attach points on the F40, you might want to try to flip the direction that the cables come from.
I chose to do that in this video.

That weight gives the 1-2, 3-4, 5-6 gear changes 'feel' so you get some feedback through the shift cable. It's a personal thing if you like it or not. Some people remove the weight (part or all) and some people add more weight to tune the 'feel' to their liking.

Ok. Ok. I see you Ross. That is not a way I had thought of. So you're saying create a mount somehow, and come from the front of the car going towards the rear.

Poor angles, but at a straight shot I'm sent right into the ECU/Fuse Box assembly. I see in you're video how far you had to go out to get yours to work. I'm going to investigate this further.

My right hand drive mini truck (Subaru sambar) had a regular 5 speed shift pattern. Took a little getting used to but it worked.
