    Default Replace DME Relay and Fuel Pump Relay - not expensive.

    Have had 3 incidents of the "Trans Program" warning at about about 6 week intervals. I'm getting concerned and looking for remedies. Have change the trans filter and added new oil.

    Can someone explain why doing this:

    Replace DME Relay and Fuel Pump Relay - not expensive.

    will help?

    I don't see the connection.

    TIA

    Jim

    i think the DME relay controls a ground to the trans comp. (or maybe forward voltage)

    a bad ground to the trans computer would cause the error.

    if you havent replaced the fuel pump and ecu relay you should do it anyway.

    Had another "Trans Program" warning so ordered the relays. Like a sheep following the flock I replaced the 2 relays today . Hope that is the cure.
    Still, I'd be interested to know definitely how/why these relays will help.

    TIA

    Bill,
    You have had experience with the "Trans Program" and the replacement of the relays?

    I made several threads/posts about my "Trans Program" with limp mode problem. Tried several "fixes" but bottom line is I changed out the Pulse Generator ($40 from stealer) in the transmission (remove pan and it is right there, very easiy job) and no more "Trans Program"!!!

    i was able to throw a trans program instantly today, by unplugging the shifter lock solenoid.

    another place to look at before having a trans rebuild.
