Converter unlocking during hwy driving
Lately it's taken a bit longer for my converter to lock but I heard that cooler temps will cause this so I wasn't too worried. But lately, if I'm crusing at 70-80mph it will just randomly unlock then lock back up in a minute or so. There's 74k miles on my tranny. Any guesses?

Just looking at some old posts (really old) and I found that the converter supposedly doesn't lock up until the trans temp reaches 149* F. Which also means the converter will unlock if it drops below this number, which might explain why mine now unlocks if I'm on the highway in the cooler weather. Hopefully this is the case.

you can disable p300 and still get misfires. it just wont set the light off. you can go in and adjust the misfire detection table to fix it if its atcually misfires thats causing it. you would probably have to atap or efi live it and see the misfires on each cyl while driving when it unlocks.

if you're computer is still detecting missfires then that is why ur TC is unlocking. have it desensitized so just the major missfires are detected. I know this was a HORRIBLE thing I had to go thru after getting my H/C combo put on...the X1 cam even during normal driving would put out missfire codes...I went back to MTI and Let Jayson work his magic and have since had no trouble. Only thing you truly need to stay on is your Knock sensors and even I had those slightly desensitized....*shrug*...
