Answer 1

I think you have a vacuum vale problem in the sump of the gear box or the vacuum tube from the engine to the gear box is leaking.~~

Answer 2

sounds like a relay that alerts the computer of the rpms of the motor that makes it change gears. It is probably a relay or a speed sensor. I am sure you can take it to autozone and they can hook up the diagnosis machine (for free) and they will be able to tell you the code that shows up. That is the cheapest way to find out. Some are easy to change and some are difficult.

It is not the transmission fluid because the tranny would slip or jerk all the way through all the gears. Good luck
