Slow down killer, If you already have a E38 ECM (1st pic), And remove the TCM/Control Valve assembly. You can send both modules to Speartech for reprogramming. NO need to buy new.
I would like to idenify the ECM you have, The second pic is a E40 ECM..Later E67 ECMs look similar...3 plugs. The E38 ECM you need has 2 plugs.
If you need help removing/installing the TCM let me know.
