I have a '95 Countour GL with 162K (yes, I know I've been lucky.)
Yesterday while driving down the highway the transmission started downshifting.
Now at any speed over about 30 or when in third gear it keeps downshifting and making tremendous jumps and lurches. You can get the car up to hiway speed, but when it does need to downshift (pulling a hill) it goes berzerk.
After the car cooled down for a few hours it drove better until it heated up.
Any suggestions as to the problem?
you can email me at: dbbubba@earthlink.net

Sincerely,
Danny Brown
