1993 ld2500 4l60e, I lost 1st and 4th. I replaced the A and B Solenoids only to test the old ones afterwards and find out they were still good the trans is only a few years old and was rebuilt with extra clutch packs, the fluid looked good but I changed out that and the filter, what are my next steps? Idle Air Control Valve? What tests can I run without an OBD1? any help would be greatly appreciated
