2003 Excursion Transmission Issue
I have a 2003 Excursion with a 6.0 Diesel. My tranny seems to shift quite often. Is this the tranny going bad, do the shift points need to be adjusted? Still seems to move just fine. Has anyone has similiar problems? Thanks a lot for your help.

Thanks Mark
Seems to shift at about 45 to 55 mph, anywhere from 1650 rims to 2000. Seems to shift very often. If I tow it is terrible even with overdrive turned off. If I am going 75 or so it seems to be ok. Thanks for your help

Interesting. On a 2003 6.0L there is no way to turn off overdrive.
I think you will need to find someone with a high end scan tool that can look at live data. I think the computer is getting some bad data.

Not sure if you've recently replaced or removed the power from your truck. But
Any time the battery is disconnected for any reason, including dead battery, a new PCM has been installed, or the calibration has been reflashed, the adapts for the "Engagement Schedule" should be reset. This procedure will prevent the customer from returning with firm or harsh shift or engagement complaints. Proceed as follows: Note: All of the following engagements must be performed, in order for engagement pressures to correctly adapt with the new calibration.
1. Install diagnostic equipment (or use suitable Thermo device) and monitor TFT (Transmission Fluid Temperature).
2. Warm the transmission to (130°F) as indicated by the TFT.
3. Perform 5 engagements from Park to Reverse. Each engagement should be five seconds apart.
4. Perform 5 engagements from Drive to Reverse. Each engagement should be five seconds apart.
5. Perform 5 engagements from Reverse to Drive. Each engagement should be five seconds apart.
6. Perform 5 engagements from Neutral to Drive. Each engagement should be five seconds apart.
