[DML] Re: Auto trans shift Kit

["Welmoed" <welmoedj@xxxxxxxxx>]

Resoldering, yes, you're right!
However knowing old electronics, most of the guys that are going to replace parts will also inspect the solderwork.

And the two caps over the ICs, yes, that's a slip of the mind: ceramic is the way to go there.
