Xantia - Automatic

[Abrahaj]

Hi,

 

I have a 1995/6 Xantia 1.8 Automatic.

 

I was just wondering at what speed / revs should the gears change if all is working OK.

 

Mine goes into 3rd at 2500 revs - this is just on 30mph. It goes back into 2nd if I slow down to 25mph.

It goes into 4th at just over 40mph - about the same level of revs and goes back to 3rd at 35mph.

 

Just want to know if this is running as efficiently as it should - MPG sems to be very low even for an automatic. Although it seems to be better since I changed the front Spheres.

 

Any help gratefully received.
