I have a 90 fwd fleetwood and i get a e39 code which i understand is torque converter engagement code. i replaced the ecu/prom and so on. the light comes on quicker now. whereas b4 it would come on after 2-3 miles of driving. i read all these posts for it but is there anyone that can give better details or know wat to replace if so directions to do it. and also is this a bad code.

I can't give you much help on what or how to replace but I don't believe it is a "bad" code. It means that your torque converter is not locking up above 41 MPH so there is minor slipage. Worst case to my understanding is that you will run 100-200 higher RPM at any given speed and your fuel milage may suffer by about a MPG.
