New OEM E40 ECM and T42 TCM Combo

Need a spare ECM and TCM for your vehicle for fear of warranty issues or do you simply want a spare set? WAMS has you covered with the lowest prices and newest inventory. Our ECM's and TCM's are current production units that come programmed from us with the current GM calibration release VIN matched to your vehicle. Since these are new units there is no security relearn required but your vehicle will require a Crankshaft Position Variation relearn.

PLEASE NOTE: E40's are not stocking units and may take longer to ship than stated as we are at the mercy of the supplier on small orders; thanks!
