Manual transmission genius needed

So I've run three parts stores including one of mine own,worked just as a counterman at 2 more. My bestvyear I sold 1 million 500 thousand dollars worth of parts. I've seen what people bring back. These people cost everyone money. Example 1 part store I worked at a guy bought a battery,the next day he bought a starter then he came back to warranty his new battery,then he bought an alternator. He returned the starter,no box and greasy we warrantied a battery,and what he needed in the first place was an alternator. Will you pay full price for the returned battery,the starter that's obviously been installed? There's tons more many costumers abuse the good will and customers always right attitude of parts stores. Techs that buy new belts then return their customers old belts under the lifetime warranty.I could go on and on Dennis asked someone a question about their water pump,customer response,they're all the same! No sir I need to know whatever he needed to know.The man answers takes the pump installs it,its the wrong depth because he didn't answer the question correctly. This is employee time, this is extra merchandise cost, think what you want but using the parts store as a test part library socks for everyone except the person doing it. Twice in the last month or 6 weeks on a different forum people giving advice just buy everything it could possibly be and return what you don't need. I told them that's a d!ck move.

Regarding the fill port: I've done them just to preserve my sanity.
I borrowed my wife's ex's Escort for a trip, didn't really know what I was doing, thought I'd help out by changing the fluid in the 5-speed. Drained the fluid, then discovered that I couldn't remove that speed sensor. Ended up paying the ex for a tow to have the dealer remove it.
Four years later, I won the car, now it needs a clutch. got it done, take it out, clutch is good, but randomly I'm locked out of various gears. In reinstalling that speedo gear, I thought I was running into opposition from the sealing o-ring because the plug is such a snug fit. Wrong. The two gears weren't meshed properly, I forced it, and the gear ended up at the bottom of the case, where it was blocking the shift mechanism. Pulled the transaxle, opened the transaxle, retrieved the gear & clip (undamaged), reassembled the transaxle, reinstalled the transaxle, drank heavily.
Another few years, another Escort, another clutch, fill the transaxle, reinstall the speedo thing, car runs great, but no speedo action. I'm not sure exactly what it is (for this one I used some heat shrink tubing to ensure that the clip stays put). I no longer CARE. I don't need a friggin' speedo! I just need to NOT go back in there again. here are photos of my fill/check port, this allows me to drop a dipstick straight down past the inside of the "elbow" of the air inlet. I've seen several times that it'll leave a puddle of ATF at startup, and it's pooling on the top, so I guess I overfilled it, and it's leaving via the vent. This motor/trans was used in the SpecRacer Ford series, and there's some suggestion for purposely leaving the level low, so it doesn't drain out and make a mess when you pull if you change the axles. Sounds crazy.

Here's what I have in mind on post 1 I asked if there was any place to drill a hole for transmission fill. Well I think someone can figure out (I will figure out just not immediately) where we can drill a hole in the sheet metal transmission to check fill level. A hole drilled X.x number of inches from some landmark on the pan.You fill or check from the weep hole just like most manual transmissions,differentials and even holley carburetors.You seal the weep hole with a sheet metal screw and a rubber washer. For filling you pull the factory vent off the Transmission you add a short piece of rubber hose and use a G.M. differential vent they clamp into a 3/8 hose. Anyway someone,maybe me needs to figure out where to drill the weep hole and/or if it's possible to drill a weep hole big enough to act as a fill port also and use an automatic transmission add on drain plug to seal the fill/check hole.
