    6.4 Trans tables

    There seems to be no way to modify any trans parameters on my truck. Ive had this happen even on a gm gas truck before. the tables are blank. My truck file the only thing that shows up is "gearbox protection."

    Is there no way to work on Tq converter lockup and shifting?

    Has the truck been tuned prior? Post up an info log while connected to the vehicle.

    I pulled the file out of the truck and now its all there. I keep changing tw converter lockup but it still wont lock until over 50mph.
    Who has experience changing this?

    What are your apply/release speeds set to on the Auto TCC tab?

    Ill take a look today.
    I couldnt find the trans tables because I have like 5 files that I built out of one particular file. I had to read the truck to get it back. If anyone else has that problem.

    It lost like 5mpg without the converter locking.
