Overdrive cutting off during normal driving

Yes. The vacuum line from the cruise control assembly under the battery box connects to the throttle body on the drivers side. It also branches off the same line, at the throttle body, and goes to my blend door control with two other lines that go through the firewall into the cab. There are two check valves in this area of the system. One right off of the throttle body then in one of the lines that go through the fire wall. Trying to get some pics together. Also I traced a large vacuum line to the rear of the cab on the passenger side that has a round canister and a rectangular canister. Looks like one of these lines are for the fuel tank. Anyway one large and one small line was completely off their respective " nipple" or connection point, and badly cracked and deteriorated. One is just a 1/2" tubing with a 90 degree into the rectangular box, but the other is where two smaller lines go into to single " nipple" or port on the round canister. Damn a vacuum system!!!

If this pic worked, this is how my lines run. And I'm probably wrong on the term throttle body/ intake!!! And I can't type as the picture comes up!!! But you see what I mean! Thanks again!!

Transmission shops have a scanner that can read transmission fluid temperature. A good one will have free or cheap diagnostics in the hopes that they'll get your business if they find an issue.
My transmission overheated and kicked out of overdrive the day I bought it, I was told it was a bad torque converter.

Alright first of all my apologies for basically having two different problems all in the same thread. I'll work on the vacuum leaks later.
I have removed the check valve in the cooling line of the tranny. Soooooo... After changing out my rear brake cylinders, shoes and hardware, I noticed two drops of oil from my tranny. I snugged up the pan a little and took it for a spin to test the brakes. After being grateful that everything tested good and being able to get up off the ground, I parked it. Treated myself to a cold one!!! Went back out and notice tranny fluid had been leaking out. I should say pouring out. Upon inspection I realized that I had squeezed the Tranny gasket out. I did use silicone when I did the filter change. And torqued to required specs. So I ask, reuse the gasket with or without any sealants? Or get a new one? Also your thoughts on the governor solenoid and pressure transducer since the pan is coming back off.
Remember when my knocking motor turned out to be the tensioner?

Replace the gasket with one of the good ones. (viton, or whatever it is, it's reusable.) Don't use any sealer. When the pan is off, make sure the bolt holes aren't dimpled. If they are, flatten 'em out. Don't overtorque when reinstalling the pan. There is a spec for that, and a pattern, stick with it.
If you electronics are original, go ahead and replace them, adjust the bands while you are in there.
