ok easy problem but your gonna gave to pull and do a little research.

first part
go out and see if you find a cable undone located about where the tailshaft of the tranny "WAS",,
this would have hooked up to your speed sensor

second,, locate the speed sensor on your new tranny and wire it up to there.
you not going to have MPH function until this connector is fabricated up to the speedsensor on your new tranny.  Something tells me a chevy guru needs to be your buddy right now.

thats your problem,, get your existing speed sensor connector hooked up to where the speed sensor is on your chevy tranny.

HEY!

I'd have at least used a FORD I6, if I had gone through with my ideas.. :p

It might've been the one and only time I'd ever have considered using a turbo, too.


Time to drag Oldraven in here.. heh.

A Turbo 400 won't have a speed sensor.  They used a cable drive.  Might be an aftermarket company (Dakota Digital, etc.) that could fix you up with something that would work.
