stumbling in OD fix...Maybe...

I have a 2000 2wd EXcursion. 7.3 3:73 gears. Just picked it up from California. Love it.
It had a bad stumbling feeling in OD at 35-45 mph. Seems to go away at higher speeds, Like the engine is missing. She runs like a top. Anyway, I took it to my local ford dealer. He put it on the scanner and it threw no codes. He drove the unit and agrees it had a stumbling that did not sound like a miss in the engine. Couldn't help me....
So I found on this forum A guy named Rick who had basiclly the same problem. The switch in the gear selector was the problem. Guys not the switch per se but the wires in the shaft where they come out of the tube.
there a little nylon grommet that keeps the wires from rubbing on the tube.
right there under the shrink wrapped wires at the bend ,all of my wires were brown and starting to melt together. I've seen this before . I think the nylon helps to retain the heat of the power lead side of the switch. I'm thinking maybe a lot of weird trans problems could be originating right here long before you get a failure or even a code thrown.
I had no OD light flashing, no codes, cost me 57.00 for the whole shift lever assembly. Going to change my fluid again before our Alabama trip. Thanks Rick
Hope this helps someone. OH the parts and service guys didn't think this could be the problem....never seen it before... I'm going to go show them this design flaw maybe a recall is in order....

I too have a similar issue. Thanks for sharing this as this may have just saved me from replacing my tranny as I am experiencing the same issue. I'll give it a check tomorrow!
