Well, a fluid change did nothing to get the transmission to work, but I did
notice something strange in doing some troubleshooting...in trying to
retrieve the trouble codes for the "engine" light, I would not get any
flashing of the engine light after shorting the connector pin. Does this
provide a clue to something I am missing?

Thanks,

Mike

You didn't mention (in your earlier post) that the check engine light was
on. If it wasn't on already, then when you short the 2-P connector, it will
only light up (to show you that it *can* blink) and will not flash out codes.

Was the engine light on in the first place? Also, have you tried reading
codes out of the transmission (it flashes D4 light I think)

Arthur, yes...the engine light had been on (O2 Sensor) prior to the trans
failure. I am not sure what you mean by "reading codes out of the
transmission (it flashes D4 light I think)". Please advise...

Thanks,

Mike

Oh, sorry. I don't have an automatic and I'm too lazy to dig up my helm
book right now, but you can read DTCs (diagnostic trouble codes) out of the
automatic transmission's controller much in the same way as for the
engine's ECU. If no one else posts how, I can look it up...but as I recall,
there is only one service jumper, and it makes both units blink out their
respective codes.

Obviously the meaning of the D4 light blinks will be different than for the
check engine light blinks, so there's a separate table. When you short the
service connection, does the D4 light blink, or light up, or nothing?
Again, I don't have an auto and my memory of the book is vague.

Anyone? Does the service connector cause an automatic to read out it's DTCs
as well, or is there a separate procedure for putting it in diagnostic mode?
