OK put a fresh engine and rebuilt tranny into s10 blazer zr2
runs good, tranny seems fine.
HOWEVER, will not engage into 3rd or 4th no speedo, no cruise. Tranny guy said elec. conections may be loose or not connected. they are connected near the tranny. is there another place that I can check. is there away to check circuit. Got an OBT 2 code PO502-vehicle speed sensor ciruit low input. ???
