Hello all, this is Martin in Ohio. Just replaced the TCU with a used unit and seems to have resolved the Gearbox Fault issue for the moment. However, noticed that the TCU unit is not fastened down or bracketed inside the firewall box, but lays loose and untethered. Can anyone say if this is the way Jaguar made it, or am I missing a hold down bracket or screws?? Could be the reason for the old TCU failure (i.e., bouncing around loose with no fasteners?).
Thank you,
Martin
Mine has a black painted fabricated bracket that covers the connectors on the ECM and holds both modules. This is secured with anti tamper screws as is the cover that encloses and seals the whole compartment.
