The problem with the car is that the there is a bad shift from 3th to 4th. The change is delayed and, also when the first speed changes to the second one it works but not smoothly. One mechanic told me that the solenoid sensor in bad, but other mechanic made a test to the solenoid and it was okay.
I will change the transmission oil to see if this action will fix the trouble.
My question is: It is necessary to change the filter also, knowing that the filter is located inside the system? What are you recommendations?

Good morning,

Changing the fluid is a good idea. There could be dirt or debris not allowing the valves to work properly.

As far as the filter, no, the transmission has to be remove and the case split apart to access the filter.

That was not a good idea. If there is dirt or debris in the filter, it can travel to the valve body and bring back the issue.

It is possible but if you get me the code, I can narrow the area of failure for you. A parts store will read it for free for you.
