I'm planning a 6speed swap on newly purchased 03 RS6. The current transmission seems to drive perfectly fine to me, however, it has the following recurring codes:

Address 02: Auto Trans Labels: 01L-927-156.lbl
Part No: 4B0 927 156 FL
Component: AG5 01L 4.2l5VT USA 0305
Coding: 0000002
Shop #: WSC 00000 785 00200
VCID: 76ED1A72026C6EA80B0

2 Faults Found:
17125 - Torque Converter Clutch
P0741 - 003 - Stuck OFF / No Power being transferred - Intermittent
18258 - Powertrain Data Bus
P1850 - 003 - Missing Message from ECU - Intermittent


When I pull the trans, what is it worth on the used market. I am in Canada, but have no problem shipping to the US, if needed.
Transmission has about 50K miles
