Well best of luck with it Ryan... I really don't think u fixed problem just delayed it for a bit... Mine would come and go and the reset never worked for me.. So I replaced apps sensor and still had the problem .... I got some videos I am gonna post soon as I get time :banghead:....so that way ppl can see if I was having the same problem as they are...

Hey.... Have you looked at your plugin and wires on back of alt?.... That was my problem... Try unplugin it and plug it back in. Had bare spot on wire .... Tiny tiny spot.... Also how far did you drive?... Mine wouldn't stop acting up till voltage gauge went down and check gauges light came on....

Hey guys I believe I am the person Michael is talking about when he created this Thread... Seeing as how I replaced both batt. new alt., new apps sensor... took it to best diesel shop in town and they tin foiled the wires and added a new ground wire to the apps sensor...still having the same 4th gear hunt and loping at idle... took it to shop 4 or 5 times and they kept throwing parts at it till they finial said "we dont know whats wrong with it, you can keep throwing money at it and eventually replace the computer"... talked to Michael on phone one day and he suggested pulling alt. fuse and run down the road and see how it acted...Wow no more problem!! so im living proof that the band aid stuff doesnt always work!.... did a voltage check and sure enough the ac voltage was thru the roof... so replaced the alt. agian and done great for bout a week then came back hard and strong!! every gear was doing the hunt..and ac voltage was high agian!...so i got to looking at the alt wires and seen where the green wire going in to the plug on the back of the alt. had small bare. I messaged Michael and asked him about it, I believe he said the green wire had something to do with the pcm so yes it could be putting out ac current..( correct me if im wrong Michael... just got off work and have had a couple of drinks) ...so I wrapped the wiring of the plug with electrical tape and bam problem fixed!!!...havent had any issues for a couple of weeks now...I have made videos of my problems and fixes so I am working with Michael to write a article up on it because ladies and gentlemen we have found the cure to the famous 4th gear hunt! and I owe a HUGE debt of graditude to Micheal Nelson for helping me figure out the problem... we have talked on the phone and messaged each other no telling how much! lol but he was patient with me and he figured the problem out!.........so agian thank you Michael!!
