307 sw automatic transmission oil and dipgas

Greetings I would like to know how long the oil of the automatic gear we use in our vehicle remains, how it is maintained. And I had a problem in the course of the cruise, I pressed the gas to the end of the road, the car 1.6 307 sw auto-row autogas system, I noticed that the car did not accelerate in the last gas, when I told a friend, what I expect from the 1.6 car is actually nothing to do when I look at my right hand side, I saw that the taurus almost passed by my way. It was over 90. My guess is that if it is stratified according to the plain gear, how hard it is pressed, low gear should be high speed, but at low speeds that I said, for example, between 50 and 90 is okay. We have also made the maintenance of the car, the engine water cover has changed, 4 pads etc. oil has been looked at, but I have to remember that the reason is 1.6 because there is a technology difference between the vehicle reaching me at the same speeds and 25 years. I think you cannot withhold your comments Regards.

Check the spark plugs and cables for coils, etc.

You have to lift the car to the lift to check the oil. The transmission oil is only controlled as such. If the screw is loosened, it is normal if the oil flows like a thread. It is less if it drips. An average of 60 80 thousand km of oil should change. If it comes to negligence, it starts to trouble the solenoids and opens bigger problems. When it comes to speed, my car 1.4 is automatic and very agile. Have your spark plug air filter check your lpg filter. The 1.6 engine is not the engine to be thrown at all. Also, if you make bottom throttle to the automatic gearbox, the gear shifts down and the speed increases, so you can accelerate quickly. If you quickly smell the throttle, if you don't shift down and accelerate, there may be other problems.

Thank you very much for the information you provided, I will look at everything before I enter the visa, thank you.
