The more info you give us the better we can help.Yea, OD light blinks with key on.
I just don't see how the trans is done, when it was working fine 20mins before??
I did notice the speedo is jumping around all over the place, could that be affecting it?
:whs:Blinking with the key on indicates an electrical problem is present in the transmission, usually its the solenoid body. Did the bouncing speedo start when the trans started shifting bad? or was it like that before? at this point you need to have the codes read to find out what the problem is before you just start throwing parts at it.
