There is no improvement to be had when your aftermarket transmission motor mount snaps in two , Buying a crappy part doesn ' t mean every after market part is bad . necessitating a trip out of town with another car to retrieve the OEM mount from my place , then having to find and pay a mechanic on a Sunday to install said mount . Being bad at fixing your own car isn ' t the fault of aftermarket parts . Not to mention , usually OE parts that aren ' t made in house are made by the lowest bidder , and the result can often be some pretty garbage parts , regardless of how much time and engineering went into making them . I work in parts Ford Infiniti Bodyshop and I can definitely attest to a garbage that is Ford stamped metal parts , and no one could possible argue a forged aftermarket arm is inferior to a stock stamped piece .
