Alright ladies, as promised here's an update on the tranny work.
Last night I replaced the throttle valve cable with the new one I ordered up. Quite a job as I had to drain the fluid and drop the pan to get to the connection inside the transmission case. Took about 5.5 hours from start to finish. I could probably do it in three or four now that I know what to do. A lot of time was spent figuring out how to get at things and how to remove the existing one. The TSm gives you like a paragraph explaining it with no pictures, lol.
-First step, jack the car up!
- Next I pulled the filler tube off the pan to drain it. Cleaned the outside of the pan as best I could. When it comes to work on transmissions I've always heard clean is king. You don't want to get any grime or grit up in there or you'll score parts and ruin it when you start the car up and run it for the first time. So I took my time and worked slowly to ensure I didn't get crud into the internals of the transmission.
- Once it drained, dropped the pan and removed the filter. It's a fiber type filter and I had bought a replacement for it however the replacement is the wrong one. Turns out it was for the other automatic transmission they used that year. I found the right one online today now that I knew what it was supposed to look like. It's actually a filter kit for a Ford FMX transmission which after some research I found out Ford sourced from Borg Warner and the case and extension housing, except for the internals, are the same as the Flash-o-matic in my car.
- I cleaned the pan throughly once it was off the car. The fluid in the transmission was clean since I changed it when I did the motor swap. There was some nice grey black residue in the bottom of the pan though. Dropped the new gasket on there to make sure it lined up.
- Now for the hard part.
Getting the throttle cable disconnected from the cam inside the transmission case. The manual wasn't too clear on this part and after visually inspecting, it looked like I might have to drop the take the control valve assembly and pumps out to get to where the snap ring on the cable end attached to the linkage connected to the cam. After puzzling over this for a while, I saw there was a bolt right next to where the cable enters the transmission case and had an "aha!" moment. That bolt presses the flange on the cable against the case holding it in. So working in a hole with about 4inches of space, I got that bolt out and had the cable flange loose from the casing.
Here's the opening between the frame rail and the transmission where the cable comes in, TIGHT!

- So now I was fairly certain that I should be able to disconnect the linkage on the end of the cable from the pressure valve cam inside the transmission. I just couldn't figure out how to do it. The linkage for the shifter arm comes right through the side of the case next to it and it holds that linkage in the hole on the cam. Went back to the TSM and had another "aha!" moment. It said "depress the pressure cylinder and rotate the cam past it". I hadto push down on the little cylinder that the cam presses against, to push it in further and out of the way of the cam to rotate fully past it exposing the linkage in it's slot. Here's some pics showing it:

- Once I had the linkage disconnected I was able to remove the cable. This all took about 3.5 hours. Whew. Putting it back together was easier. Here are some pics of the cables so you can see what I was talking about, having broken the threaded end.

-At this point I just needed to put the new cable back in, re-attach it to the cam, ensure everything was moving freely and button the transmission back up. I got it all back together without further snags and finished cleaning up around 1:30am. Long night.

I'm going to drop the pan again to put the new filter in when it comes so I didn't put the filler tube back on yet or refill it with fluid. I wanted to get it all covered back up though so nothing would get into the internals of transmission.
Mission accomplished! Next is finishing my jury rigged connection between the throttle arm on the carb and the new throttle cable.
