I just replaced the 4.3 in my S-10 with a carb 350. The Motor runs great with a few gliches here and there. Now my problem comes in when the transmission is concerned. See this is my first swap out, and well I am kinda lost as to what to do. I want to keep the tranny cause i had it rebuilt not long ago, but it will not shift automatically. The speedometer, odometer, etc. are inop. It will shift manual fine. Is there an replacement kit that takes the place of the ECM where thetranny is concern? If so where can I get one? Any other solutions I am open too.

Thanks Chris
