94 XR7 O/D light

I just got 94 with about 30,000 miles.

Does anyone know why O/D light flashes but tranny operation is normal.
If I disengage O/D & wait till car shifts to 3rd - then turn button on, it will shift to 4th & no light flashes.

If I don't do this then light will start flashing once tranny goes into 4th

Maybe car has not been driven enough & this will go away??

Thanks

if there is no malfunction with the transmission operation, you may just want to ignore it until you can have it look at by a transmission shop since the problem may just be electrical in nature ie. a loose connection. you may want to have the transmission serviced since it has been driven so little and have the transmission looked at when you have it done, remember a transmission should be serviced every 24,000 miles.

Thanks - actually I figured it out.
I put in a new battery & did not take car through the driving sequence, as described in manual, to reset the computer.

Can you share sequence described in manual to reset computer? I've misplaced my owners manual.

Driving sequence for battery change as follows:
1) Drive in typical city - stop & go - traffic for at least 10 minutes - after reaching normal operating temperature.
2) Idle vehicle for at least 45 seconds - the accelerate at part throttle to near 45MPH
3) cruise & maintain a select speed in the 30-40MPH range on level road with throttle held very steady for at least 1 minute
4) Repeat #3 but in the 40-65MPH range for at least 1 1/2 minutes
5) OBDII drive cycle is complete.


For the flashing O/D light - you might also want to check all your plug wires as this could also cause problem.

Thanks for providing codes.
