Have you checked both ends of the cables - under the shifter boot too?

Are you sure the symposer pigtail and anything else is clear of the linkage on top of the trans?

 

Haven't checked under the boot, anything under there I should be looking at in particular? I've checked the linkage multiple times and there's nothing in the way

 

What shift mods do you have?

 

Previous owner put in solid cable bushings but the whole shifter assembly is stock other than that.

 

Have a helper shift through gears, or put your phone out in the engine bay and go through them all while recording. See if the side to side lever is moving at all (the cable with the lock clip for the neutral reset). If it is, make sure the lock clip for the neutral reset isn't allowing slop in the cable

 

Are you sure you don't have an aftermarket shift rod in the car?
I think JBR and maybe another had that issue and tweaked the cable reset procedure to make it work. Usually.

If you have a shift knob that is lowered, especially by threading the shift arm more, the stock lockout link won't work but can be replaced by a cable tie to shorten the distance.

If the lockout link is broken or missing, it could still be functionally replaced with a cable tie.

The lockout link pulls the plastic piece up.

 

Definitely move it manually a tooth or 2. I forget which direction it has to go in, though

 

This ended up fixing it, thank you so much! Don't know what the regular reset wouldn't do it but it shifts through all of the gears now.!
