Noob question 727 really low shift points

TrailBeast said
If I remember correctly I had about an inch of cable or more (the inner cable) once it was all hooked up.
I put the return spring for the throttle pressure on the trans (actually from the lever to the front cooler line) because the lever has some spring to it in it's travel but it doesn't pull the lever all the way forward without an external spring on it.
I really do think you might have yours too tight and that's why it won't shift.

The cable is made to mount under one of the extension housing bolts and pulls the lever to the rear of the car when the throttle opens.
Is this the way yours is?

So I pushed the run closer to the middle of the firewall and now I’ve got a crap ton of room. See photo. Now I just have to figure how much needs to be adjusted up top.

I also cut the front part off of the stock throttle cable and am going to see if I can just use the ends of the Lokar cable and attach to the existing cable. If not I’ll have to crawl under the dash and deal with it. I’ve tried once and am too big to be under there without pulling the steering wheel which just adds more time to getting this done.
