Subaru Transmission Cable Linkage, Some Photos with a Rule Options

[DBCooper]

I can't find the thread now, but I promised some photos of my Subaru cable linkage, with a rule for dimensions. Seem to be several projects getting to this point, so hopefully it will be helpful. I wrenched my back so it's been slow, sorry, but here are a few.

General layout. The cable going through the center of the photo is anchored on the left at the sheath to the main bracket, then connects to the shift rod bracket on the right, attached to the shift rod coming out of the transmission. That cable is the shift rod in and out. The rotational cable connects to the bottom of that same shift rod bracket, on the right. The main bracket is the important piece, it locates all the cable sheath anchors. This is the best view of the reinforcing gusset that keeps everything stiff.

Same view from below and a little further back so you an see the cable sheath mount for the rotational cable.

Same direction of view, but a little around the main bracket so you can see the shift rod bracket. That's the important dimension for full throw of the MR2 shifter, 8.5cm from the center of the shift rod to the cable heim center.

Another, that same bracket and dimension. This is the best view of now that bracket attached to the transmission shift rod:

Same components, different view. The main bracket curves out from the transmission mount to put the sheath attachment point out in the same plane as the shift rod. In the photos above you can see the shift rod bracket is bent in toward the rear of the transmission to keep that cable movement in the same plane. You can also see more of the main bracket gusset (that triangular shape). Need that gusset to keep it all stiff, minimize cable shifter "mush".

Different view, same stuff.

Shows the main bracket size. This isn't a critical dimension, but it will give some perspective, maybe help. that 5" measurement is from the point where it attaches to the transmission to the cable sheath anchor tab for the rotational cable.

No, this is NOT Andy's camera, it's my sore back. Not a critical dimension so it's OK. It's 17cm, the distance between the mounting tab for the in-out cable sheath to the middle of the in-out heim joint on the transmission rod bracket.

Layout (during the build) of the modified MR2 shifter inside the car. That verticall piece of flat stock between the cables from the shifter to the sheath mounting tabs makes the whole thing stiffer, eliminating a lot of the movement and making the feel a lot more precise. Note that there are adjustments everywhere in the system, every cable end. There's also a video of the shifter working in my build thread, ink in the sig, below.

And last but really first, your reward for reading this far, my little hot rodder grandaughter. She just wants to have fun.

Sorry things are dirty, but this is how things look with 20K miles of road grime. No maintenance done so far other than regular oil changes and a set of tires. If anyone has any questions or you want to see more or different photos just let me know.

As a community service I'd suggest that when whoever is first up makes their shifter parts they do dimensional sketches at the same time, then once it's sorted make up a dozen sets of brackets. It's just flat stock, simple and cheap. There are that many Subaru transmission projects, and no point in all twelve folks repeating the same work when one could do it for all.

And If anyone feels really entrepreneurial take a look at what it would take to adapt the bracket design to fit 901 transmissions, side and tail shift. These cables work better than the aftermarket shifters I've tried, and are far less expensive. There are more than a few people out there who would love to get their 901's shifting better. It's the perfect solution for those poor tail shifter guys, no need to convert to side shifter. I know that Ian intended to do this, and the good Dr. Evil has mentioned it, but it's still waiting for someone to pick it up and run with it. Anyone who wants to drive my car to verify any of this is purely welcome.

I agree. An 914 world, in house effort, would be nice instead of just counting on an aftermarket supplier to make this for us. And doing the 901 trans as well as the subie is a great idea.
