I put a turbo 350 trans with 383 engine (carbarated) in my 92 Firebird. so i did not need the ECM. Its long gone. What i need help with is making my electronic speedometer work with my Turbo 350 trans. Has anyone done something like this that can help a guy out?

Thanks Matt

 

There was a post on here a while back where someone mentioned that some of the newer chevy trucks used the TH350 with an electric speedo. You'd probably need to round up that particular VSS unit, and probably the tailshaft housing too, since the hole for the VSS is quite bigger than the hole for a mechanical speedo on the auto trannys. Try doing a search for TH350 electric speedo, and you should be able to locate that particular post.
