TF80SD gearbox Valve body replacement XC60

[Old Wobbler]

OK guy's. Need some help here.

These gearboxes are 'sealed for life' with no service parts according to Volvo yet when you get a code of TCM-P-074100 or TCM-D-074100 it means the valve body of the gearbox is failing or has failed.

This valve body issue with these Volvo's is a know fault and many go wrong, sadly few get replaced by main dealers at about £2000/£2500 a pop. The Valve body is £1300 on its own.

I've been unlucky to have bought an XC60 that seemed fine but developed the fault 3 weeks after buying it. (See previous thread.)

I'm now in the unenviable task of sorting the car out. (Wife wont let me sell it at auction, just to get rid of it)

So, who's had there Valve Body replaced in an XC60 or similar, who did it for you and who would you recommend to do it?

Cheers for your answers.
