Auto gearbox not changing smoothly
Have a '97 1.8 Auto, the gear change on the gearbox is not smooth at all, there are moments where it feels like the gears are "clunking" in to place. Usually happens between 2nd and 3rd and depending on the speed 3rd and 4th.
Sometimes when driving and applying a bit more speed to the pedal, the car will rev up to 5-6K and you would some how expect a change of gear but nothing happens or it is very delays an unexpected.
Would anyone know what the possible problem could be? is mechanical where by the gearbox is failing or is it more ECU type related?
Any ideas on this would be great.
