i was told it was signals or noise coming from that wire that would cause the trans to shift in and out of gear like that. ive heard of people buying the noise filter or in my case i wrapped the cable with foil the putting a splitt lume wire cover over it. this would block the noise or signals messing with the TPS, it seemed to work as soon as i put it on the truck would then shift in to OD and wouldnt come in and out. i think i have a picture at home ill try to find it later.

 

I see....interesting. Well worth a try. Thanks.

 

man thanks for all this info, i hope some pics will be avaiable soon. And it is interesting indeed.
