Um, that doesn't look like an A341E's sensor pickup. Both my A341E's have a 4 prong setup and no magnet as they use a differnet sensor type. Looks like something from the older A340E or A43DE or something. I may have a A340E unit around somewhere.
That part number suits much older vehicles from mid 80's with most likely, the a43de type ECT transmissions.
GZ10,GZ20,GX61,GX71,MX71,MS12x. My MX73(with ECT) would have this sensor pickup aswell I'd assume.
