Can anyone take a look at my tune and let me know if there are any issues that would prevent TCC lockup. As soon as i hit around 70 it will lock and then immediately unlock. I can lock the converter with HPTuners and it will stay locked. The trans was just rebuilt by a reputable rebuilder so I don't think its a mechanical issue.
Can't tell much from your log file. Need to log current gear and go ahead and throw all the TCC monitors in too. Whats the rest of the combo, tire height, gear ratio? Have you used the bluecat software to create your shift tables and lock up speeds?
265/70/17 and 3.23 gears, the motor is a 5.3 with a BTR stage 2 Turbo Cam. I used the Bluecat tuning software for my trans tables. I'll do another log tomorrow morning and post it when i get to work.
I actually think the misfires may be an issue for me as well, I logged misfires today and had over 1000 on cylinder 5 on a 45 minute drive. If I manually lock the converter I can definitely feel the truck is misfiring.
I believe that the knock sensor were too sensitive when I had my segment swap done they were never desensitized it could throw codes idling after I had fix my coil pack. After I had my tuner turn them down everything is good now.
