Good day everyone

I do have a problem with idle fluctuation, but are working on it.I just want to know what could be the cause, if I drive on open road gearbox works well but when I drove in town after open road and the car is warm then the automatic gearbox doesn't want to change normal.It takes longer to change to the next gear.What could be the problem,as I said I aslo do have idle fluctuation when car idle(engine warm).Can it be the gearbox or something else.Any help Please.Thanx

 

check your egr valve and clean it out. this will cause a warm engine idle fluctuation. then see if your trans does the same.
