It has 256,261 miles

My security light keeps going off and on and sometimes off and sometimes on to where people are saying that that's the problem of my battery dying

First it was hard to get it out of park then reverse would only work once in a while and now all gears only work once in a while

I can't hear my fuel pump come on. The car has high miles but runs great. I shut it off and went to start it and it won't turn over

Cooling system will pull all antifreeze from the overflow reservoir. When you start the car and accelerate you will leave a white cloud of exhaust behind you. Doesn't seem to be a problem with warm engine. Pulled spark plugs and they all look white and the same.

i tink my need supercharger oil

Will it make car run a little while and then die & not start for a couple days then start and run good then die & it repeats checked pressure with fuel pressure tester
It Had pressure at one point I check again it had none

The hood the engine coolant was bubbling over. Then I looked under the car and transmission fluid was pouring out and a piece of plastic had melted off from something. At first I could only get the car into reverse and after more fluid leaked I couldn't get any gears at all. I changed the transmission filter and put transmission fluid in but as soon as I started the car all the new fluid leaked out. What could my problem be?
