Not much time to go over the van but, the door sticker is July 00 so I'd say it's a 2000. Boating season has begun so that's taking up my time, at the moment.

There's a signal generator on the trans/speedo. Is this the reason for having to have manual trans ecm? If that is required to operate in closed loop, then I assume it generates a signal, to the ecm? To function properly, does the ecm have to generate an output signal to a speedo or, can I dead end that output? Pretty sure I can make a mechanical gear box (GM uses them alot) trans/speedo adapter with a double output and run the mechanical speedo and the sig. gen. to give the right input to the ecm.

Lastly, (for today!) where do you find the best tech books/schematics for these?

Thanks a bunch!
