I'm back with more crap to discuss about

This time the problem's the autobox.
When cold it changes smoothly and gently, but when warm it changes mood into what you'd call hysterical. Rough changes - 2nd into 3rd and
vice versa) + depending on the weather? it switches into spanner mode and I only have 2nd and 5th/TOP GEAR.

The car itself is fine, but the gearbox is driving me up the wall I might reconsider a 6speed manual 3.0CDTi. I still fear the 3.0's cylinder-liners problem .

Please guys...help me?!
