Tranny
So my tranny wasn't shifting and I took some advice off here and went to look at the modulator valve and come to find out the hose that comes off it which I'm assuming is the vacuum line was dry rotted apart...like it's a piece about a half an inch long left and connected to nothing...wondering if that would fix my problem?

Brakes
My master cylinder has no seal on the top to create a good vacuum I was wondering if I replaced the seal on there if you think that in combo with bleeding my brakes again would possibly make my brakes work. The reason being is when I put my foot on the pedal and start it it doesn't go down as much as it should...just wondering any input is appreciated.

The cap for the master cylinder has really no effect on their operation. Yes, it should have a good seal, since you need to limit the amount of exposure the fluid has to the atmosphere (it will absorb moisture if left exposed - that's bad), but it has no effect on functionality.

My power brakes are pretty stiff, but they work REALLY well.

It's possible that you have a bad booster? How does your #8 spark plug look?
