Q: back in april i posted about a torque converter lock-up problem that i was experiencing on my 2000 cummins 2500. since that time every time i drove the truck at about 45 mph the torque converter would jump in and out of lock-up. for months i dealt with it by stomping on the accelerator or eventually it got so bad i had to shift out of overdrive especially while towing. i tested what i could on the apps and the brake pedal without solid conclusions. anyway it eventually got so bad i had to do something. as a last drastic measure i tried these two fixes and if they hadnt worked i was off to buy the $480 apps the next day. the fixes were to reset the apps and to reroute the alternator ground wire. well to my surprise one of the fixes worked dont have a clue which one and the problem hasnt presented itself again in 2 weeks/500 miles. the only suspicious thing i observed was the ground wire was laying across and in contact with the alternator so i relocated it and shielded it. if that was indeed the problem kudos to tony garcin at dunrite converters for sharing! it could have been a long time before that was discovered. while i dont know which fixed it if the problem reoccurs at least i know its electrical which gets me somewhere and i suspect if its the apps it will resurface. anyway thanks to all who responded. i offer this in the hope that it helps someone else along the way. while i was on a roll i finally installed the fuel pressure gauge that roy and tom had advised years ago. it was an easy fix with the parts from genos. jack how to reset the apps http//www.dieseltruckresource.com/faq/faq.phpdisplay=faq&nr=128&catnr=7&prog=1&lang=en how to shield the alternator ground wire http//www.turbodieselregister.com//index.php about 2/3s down the page original post .
