The seal is provided by a copper washer.
I’m told by an original owner of an early build 1970 that the washer wasn’t initially used in production and leaked badly as a result. The washer was added later in 1970 production to eliminate the leak.

TCS switch seal
When I removed the broken switch from the transmission, I found 2 copper washers. The previous owners had broken off the plug on the outside and removed the steel ball on the inside and brazed the hole shut. I saw in the Chevrolet Chassis Overhaul Manual that in the transmission break down, a gasket was shown but I didn't know what it was made of.

TCS ( Transmission Control Spark System ) it operates in controlling the vacuum to the vacuum advance on the distributor.
The vacuum is blocked until the transmission is third or fourth gear, or when the motor overheats.

When I was researching the TCS system on my 73 and putting everything back to OEM I had one of those light blub moments and said no way that is going back on the car. One example of GM engineers getting it wrong by being force into bad emission regulations.
