Why does overdrive light flash?
I am a retired transmission specialist and I went completely through the
transmission and replaced the solenoids and all gaskets. I changed the valve
body and the neutral safety switch. Is there anything else that I have missed.
It was working fine before I rebuilt it. This has me stumped. I hope you can
offer a suggestion.
How is the fluid level? A flashing OD light indicates an overheat condition or something else is wrong. Scan for the OBDii trouble codes will help point you in the right direction.
