I have a 2000 Fleetwood flair 31a with a ford v10, I move the shift lever to D and the trans does not go into gear. also when I move it to pos. 1 and 2. when I go to park it goes into park. I checked ...
do you mean, you watched the linkage at the tranny, while somebody inside the RV,(engine OFF) moved the gear selector ? and you verified the linkage did not move then get your vin number, chassis and year, and goto ford truck dealer and get the new cable
i would not assume it was the cable , until i verified it much more likely to actually be a transmission problem
