Bernd,

Let's pretend that I know nothing about chrysler transmissions and
everything else that I know about transmissions is based on the ford AOD.
Anyway, here's my take on what you're saying... I think you're saying that
my trans is definately electronically shifted, right? What's this vacuum
modulator that I keep hearing about and what does it do in regards to
shifting? does it work like a TV cable? I've never seen a trans with
vacuum lines attached to it before. I've done some transwork (on the AOD -
i'm a former fox body owner) and didn't come across anything like that. I
thought that all transmission function (besides gear select lever) were
based on line pressure and how it was routed through the valve body to open
specific pistons that cause the clutch packs to engage.
