hard shifting transmission E4OD BLINKING OD LIGHT+NO CRUISE
- Thread starter sandrow

A blinking OD lite can be caused by;
TC not locking up?
Hard shifting from gear to gear, your in so called Limp mode, if taking off in D you only have 2nd and reverse, you can manualy shift thru the gears, 1 - 2 - 3.
Tach sensor. Is the Tach showing RPM?
VSS sensor. Mounted on the rear diff. Is the speedometer working? Corroded contacts on the connector. Broken/shorted wire.
FILP/TPS. Voltage not set right at idle = hard shifting, or bad TPS, broken/shorted wire. Voltage at idle 0.96 to 1.02.
Cruise; Low or no Vacuum. Vacuum reserviour, can mounted on drives side fender, rusted hole in it. Bad Vacuum pump. Lo/No vacuum makes hard braking peddle.
Cruise,Electronic. Check IDI Tech Articles for troubleshooting.

OD light is flashing, pull the codes. Otherwise you could be swapping lots of parts for nothing.
