First thing I did was check the schematic. U832 pin 11 comes from the microprocessor and goes high when it wants to pass RX audio through the station. This would feed the transmitter and control line output.
TP9 is the local mike PTT input. Your PTT Priority has "L" in it so this would allow the local mike audio to go through the station as well. I'm not sure, but I think that the MSF will only let one audio signal pass through it at a time. This is why there's a PTT Priority field. You've got "LW" so the local mike has priority followed by the wire line. If this does operate as I think, once the mike PTT line (TP9) gets grounded, this shuts off any other audio source and routes mike audio through the station. You didn't specify the pin number on U834 where you're feeding TX audio into. I think you're mixing and matching several incompatible signals here, while also trying to interface the CAT controller to the station. I'd connect a scope to U832 pin 11, feed a signal into the receiver with a valid PL, then ground TP9 and see what happens. If the COR signal goes away, that's one problem. If not, then many of my assumptions above are incorrect. Also check the summed audio output at TP1 and make sure receive audio stays there with TP9 grounded. You might consider connecting the COR and CTCSS inputs on the CAT together. I don't recall if switch or zone settings deal with whether you are using or not using CTCSS. You'll have to check and set the polarity properly. You probably don't want ANY timeouts set if you'll be using an external controller, as the CAT has its own timeouts in it. Full-Duplex should only pertain to the wireline remote control, but I'd set it to FULL just to be safe. I've never played with any CLBs or the R180x programmer, but it sounds like you're right on top of things. There are a couple of articles on the web that deal with interfacing and programming CLB stations. I haven't checked them recently but perhaps these will give you some additional choices.
