Just bought it. No 2nd or od. Not setting codes, yet tranny light flashes. Unplug round connector to tranny solenoids and it will go forward and backward. do not believe od/int band is broken. Cleared all engine codes, drive it, it winds up to about 30 mph, back off the gas, goes into 3rd. Can feel either od or the converter lock up. Wonder if the wiring to the tranny could allow one solenoid to not get power? Cannot figure why I cant pull tranny codes with my scanner.
