Sorry if this seems kind of long...trying to include anything pertinent.
1973 Mach 1
351C
C6 - stock rebuild est around 2000, B&M 2400 converter installed in 2004 as well as a B&M shift improver kit. I estimate no more than 3000 miles on it in that time (most of that time the car was in pieces).
As long as I can remember I've had to manually shift the car. Specifically coming to a stop and then accelerating again the car would not be in the right gear and would stall, especially when cold. So I manually go from D to 2 to 1 when coming to a stop.
I should note that the shifter is "off" in the car. Meaning the selector doesn't actually line up perfectly (ok it's way off) with PRND21. The car only starts in N and not in P. It has a newer NSS circa 2009.
Lately the trans has been acting funky. I had a misfire and some other engine maint stuff going on so I wasn't really concerned until I fixed all the engine stuff. I did plugs, wires, rotor, cap and an oil change. Electronic ignition so no points or condenser to worry about. So I take it for a test drive and it seems to act more unusual than it had been. Specifically if I'm in 1st I'm not necessarily in 1st, I'm actually in 2nd. While accelerating from a stop being in 2nd but 1st selected after about 100ft the trans decides that hey you really wanted me in 1st and it dropped down to 1st and then let me shift into 2nd manually. And then not back down to 1st at the next light. It kept seeming like 1st was just a suggestion and if it felt like it, it would make it available, otherwise 2nd or 3rd only.
So I get home and think gee I haven't check the trans fluid in a long time. Mind you it does not leak (or at least didn't prior to today). So I did the standard practice for checking fluid level and there was nothing on the stick. It ended up taking 2.25 quarts to bring it back up to normal level (added slowly and after re-warming it up). I do have a cooler and a deeper pan if that matters any. Adding the fluid didn't change the behavior at all.
So today I figure I might as well get it over with and drop the pan to see how bad the damage is. First thing I notice is trans fluid on the garage floor, that's unusual as it's never leaked before. So I drain the fluid (pan has a plug) and it comes out looking perfect. Nice color and no contaminants and no burnt smell. Pan is as clean as a whistle. That's good news but not what I was expecting to come out given how it's been driving.
Drivers side of pan and linkage a little wet:

And the filter, other than a couple "grains of sand" looks perfect:

If you look in the linkage pic there appears to be something not even hooked up. Is that the kick down linkage?
I followed what looks like vacuum hose (looks pretty old) off the trans to a hard line that continues into a "T" that goes to the choke (I think) and the front metering block on the carb. I pulled the line and it was dry with no evidence of fluid being sucked in.
So I'm not sure where to go from here. What would cause the leak to suddenly appear now that it was filled? I checked it hot, went through the gears, and with it idling so I don't think it's overfilled. What do I do with that linkage? How do I fix the shifter alignment and can the start only in N problem be fixed?
Thanks!
