    LQ4 with 4L60E TCC no locking up with a log file

    LQ4 with a 4L60E still some tuning to do on it , but when i got it up to speed the TCC is not going into lock up.. I am not sure if i am over looking a setting or something.. can someone look at the file and let me know. This will not be a racer ... just a cruiser and grocery getter.....thanks

    Your data says its disabled due to misfire. Looking at a file you posted elsewhere, you have OE misfire detection calibrations but you've disabled the check engine light for it. The diagnostic isn't disabled though, so it runs and fails without you knowing it. Either calibrate the misfire windows or disable the P0300 diagnostic entirely.
