Lost connection to TCM/EGS
My '05 MINI w auto transmission has lost comm to the Transmission Control Module - ECU error P1611. Tried another TCM (ebay) and no difference. Thinking it's wiring issue or can bus issue with one of the other 4 modules on the CAN (IC, ABS/asc, steering angle, ecu/DME). Does anyone have wiring pinout on the TCM so I can check if it's got power?

Found wiring diagram here, page 136: http://wtxmc.org/MiniCooperDocs/WIRING.pdf and I have 12.35v at pins 24 & 25 on the X19561 connector. So it's got power. Must be CAN bus issue.
Anyone want to buy it? Engine runs great - doesn't leak or burn oil, lots of good parts.
