Not if it is a manual transmission.
And it's "AFFECT" not "Effect"
No, that will have no effect on the battery.
The PCM will not affect the transmission in your car. The PCM is not related to the transmission in any way.
It could either be your transmission or your car battery. Most likely you need a new battery for your car.

When a car battery in connected to itself (i.e. You connect jumper cables onto a battery and then connect the other two connectors to each other), you create a continual circuit with the battery and nothing else. A similar effect is when you hold a 9 Volt battery to your tongue and you feel a small but continual "zap". Imagine this effect, but much greater. Sparks will appear when the connectors are first connected. Warning: Do not do this. This will damage your car battery. The only reason you should connect a car battery through jumper cables is to connect it to another car's battery in order to "jump" a car.
