Scenic automatic transmission problem

Greetings.
I hope someone can help me.
I have a 2002 Renault Scenic and presents the following fault:
in past days driving in the accelerate, as if
the speeds do not enter. Do not turn on the fault focus on the board not even the one of Chek Engine and two scanners already connected and on the two occasions it does not present any fault code or error a mechanic told me that it lacks oil to the transmission which
is automatic and another mechanic told me to check the chicote? As I am a rookie in mechanics I don't know what to talk to me.
I want to know if this is true or what may be failing.

For your attention to the present thank you.

hello. A question, does the car move? That is, the problem is that it does not grab speed? Or simply put it in Drive or any change and does not move?

My esteemed, what the mechanic told you is true, you must first check the oil levels in the gearbox, then the varillage or wiring, they are responsible for delivering the signals to the gear change display. In the event that all that was in good condition, which remains to be reviewed, the state of the Torque Converter would be reviewed and the pressure pump (if it carries). Otherwise there is to lower the box and enter a greater repair.
I hope it has been helpful

Thanks Xander for your early response.
My dear Jonny the truck turns on but nothing progresses when putting any speed.
It is something similar to when you accelerate when the lever is in parking, simply the truck does not advance.

Hello, I ask you another question, the velocimetro is very much when you place a march?
If so, your probroblem is on an axis. but if you capable have a problem in the converter or box but look good on the axes because if one breaks the differential will turn the wheel that has less resistance unless you have differential lock I hope it is something slight luck with your car greetings!
