My 2007 work van has had a random misfire code for years the shop can't get to the bottom of but that thing shifts like a dream no torque converter lockup issues ever heck that thing will sit idle with a dead mess at a light and still lock up it's got the same 6.0L 4L80E that my truck has
Its an 06 Silverado 2500hd. I can check the name of the code reader after work, it has given me a tranny code prior to the rebuild. It's odd because somewhere around 60 miles per hour the engine light flashes as if it has a dead Miss but it's running nice and smooth and it doesn't give a code...
So ive been having tcc lockup issues it just wont lock and if it does its extremely rare. So the other day i was driving with a code readed and i hit erase codes though i had no codes no pending and it locked as soon as it said erase done. It stayed locked till i let off, then wouldnt lock again...
Brand new here hopefully im not in the wrong spot. Hopfully you guys can shed some light on my issues.
Ive got and 06 2500hd with the 4l80e. Started out the tcc was unlocking on the highway as time went on it got more frequent until it just never locked up again? also i notices when in tow mode...
