You could try Lentech...http://www.lentechautomatics.com/4f27eproducts.html You could either buy an entire new built auto from them or a built valve body...there are also various parts available from Ford Racing (not sure what the European equivalent would be) such as stronger torque converters. The 4F27E is an overall gutless transmission, at least here in the 'states its not uncommon for someone to be on their second or even third transmission with only ~50,000 miles (about 80,500 KM) on the OD.
