Hi everyone
I hope I'm post in the correct section!
I have a mondeo 2 lt automatic,has 99k on the clock.
Now for my problem, when the car is cold ie. 1st thing in the morning it runs like a dream, changes gear very smoothly however when it's up to temperature the O/D starts flashing and gear changes become very erratic sometimes car goes to 4,000 rpm before it will change to 2nd.
I Would be very grateful for any advice.

Thanks in advance
