Hi all I am new to the forum. I have a S Type 2.5 auto 2005, 100,000 miles and have a slight auto gearbox problem! I get a jerky change every now and again between 2nd and 3rd, it only happens in slow traffic. I get the gerbox error message come up if it dose it more than 3-4 times and turning the car on and off seems to get rid of it. I did read up about it and it was suggested a fluid/filter change may cure it and I have done this but unfortunatly it has not. Is there anything else I can try, suggestions please!
