the most recent problem, which is still going it is this:

there is a transmission module component that is basically and overmolded circuit. There is this metal circuitry that has plastic molded over it it... and in the parts that isn't supposed to have exposed circuitry, there is like 3 microns of plastic on it.  So like... 1/4 of a layer of saran wrap, a real bitch to keep consistent. So one of our parts (from a supplier) has some of the circuit showing through which, normally wouldn't be a problem, but Chrysler's design sucks so bad, they have a metal plate that bolts on DIRECTLY on top of this plastic piece. 
So the circuit will short out to the metal plate.
