Hi. I'm a new owner of a 2005 2.8 CRD in the UK. I'm doing a deep service to give me a solid starting point. The transmission oil cooler lines have some funky connectors to the autobox, one of mine is weeping/leaking. Are these connectors serviceable? The lines are being cut further down in order to fit an aftermarket oil cooler so they are not 'trapped' on the line. Thanks for any wisdom.
