Well a leak in the tubing, maybe it has corroded away?
I don't think so. The automatic transmission is controlled by engine speed, vehicle speed and throttle position. A large vacuum leak could effect throttle position, but it would cause other problems more noticable than the effect on transmission shifting. a vacuum leak mpuld not cause trasmission to slip but a band inside transmission would cause the problem
No, but it could cause higher then average wear on the transmission.
Yes water cause leaking
Oil leak and overheating?
If you hit a rock or something else in the road, you may damage your transmission pan. If you scrape it hard enough, you can cause a leak.
Are you asking the cause of the leak or cause of the not moving problem. If your fluid is low that may be the problem right there. YOU CAN BURN OUT A TRANSMISSION BY NOT KEEPING FLUID FULL!!!
sounds like a leak in your transmission cooler lines. check the smaller hoses going to the radiator usually the bottom.
Why would you put power steering stop leak in an automatic transmission in the first place? You obviously don't know what you are doing. Take it to a professional!
Yes, that can cause the fluid to foam up and leak out of the vent.
The seal lips, in the transmission have been ripped - if the oil coming from there - seals would have to be replaced.
If you run the transmission low on fluid you can cause damage. Fix the leak.
Yes.
