Dodge Caravan Changing Box 2.5 Year 95

Hello estimated, I hope you can help me
the box is automatic and for a couple of months when the ATF temperatúra increases a lot to raise the changes.
I think it is when the temperature increases because during the first 15 minutes of functioning all the marches pass without problem.
I do not know what kind of ATF I have to acquired it second hand a year ago approx.
Thank you very much

First you have to scan the transmission to see if it throws any code and for this it has to be with a scanner that enters the Chrayler transmission system, the cheap obd 2 do not give you that function.

Greetings in the measurement rod comes the type of oil you use either mercon or dextron. Use the one that indicates the rod and then check the fuses of the transmission carry a Czech relay that is working and finally your velocimetro is the one that allows the camnbio greetings.
