Trans tune question

[mikeyss]

Good morning/afternoon. I have 2 questions about how you tube for the torque converter lockup for the 6L80's. What I'm wondering is if lockup is 100% or if it is left like the factory where it's allowed to slip more. Also, what gears does lockup occur with your tune?

Thank you for contacting us, that question would be need to answered by Justin, the tuner. Let me see what I can find out and I will message you back.

If memory serves, mine locks up in 5th and 6th usually below 45 mph and always above. I was supposed to do a data log for Justin because sometimes mine does not lock up at all but keep forgetting to run the AutoCal properly and need to ask them how to set it up.

I was curious only because I'm installing a circle d converter I'm hearing this converter doesn't like the partial lockup.

Justin can say in general "Yes, we alter TCC lockup and remove lockup from lower gears." he can't go into specifics since it is proprietary information with how he tunes.
