Well I haven't posted in a while because I've been taking a break after being frustrated with this seemingly simple process of adjusting the TV cable.
Let me start by saying that I am a confident fabricator, and Industrial Designer by trade, so I have a good understanding of how to build things in general and make them work. I have built two different custom brackets to mount the TV cable/Throttle cable, with the same results even with two different geometries. I have followed all the posts and write ups I've read online about TV cable geometry with no success. The symptoms that I had as a result were stacked shifting, shifting too soon, or too late.
I finally decided that since there are companies out there with more experience that have done the 'math' on these systems that I would just order up a bracket and cable system complete. I picked one up from Bowtie Overdrives (link below) and installed a new spring into the plunger in the transmission, which meant dropping the pan again and re-installing, installing a new TV cable, modifying the Throttle linkage on the TBI to accept the TV bracket and cam that comes with it, and also sandwiching the plate in between the TBI unit and manifold (which cannot be done without bending the return fuel line coming out of the back of the TBI because it will hit the 90° flange on the plate, picture below).

I also ditched the OEM throttle cable in favor of a universal unit from Lokar, which has also proven to be more of a PITA than it seems to be worth with this setup. The issues that I'm having now are that in order to get full WOT on the TBI through the pedal (thus properly adjusting the TV cable), I have to tighten the throttle cable up so much that it doesn't allow the butterflies to fully seat back down into the TBI causing a fast idle.
In addition, despite the fast idle which I'm sure I can fix with a spring on the other side of the linkage or maybe playing with the throttle cable a little more, I'm getting a very violent shutter between overdrive and third gear under partial throttle just trying to cruise on the freeway. I'm afraid at this point that I'm going to severely harm the transmission if I continue to adjust/test without a clear direction going forward.
I know that everything installed on the transmission is correct, does this still sound like a TV cable problem or could it possibly be a TCC lockup issue? I'm confident that I have the lockup installed correctly and getting proper vacuum as well. Any suggestions? I know there are a couple others out there with TBI and 700R4, anything I'm missing here?
