    What am I doing wrong?

    OK, First off I'm a total noob at this. I changed my shift points, line pressure, and abuse settings. I screwed it all up, but thought it wasn't a big deal. I'll just re flash with my factory settings...... Long story short it won't flash back. After 3 attempts i cant get back to where I started. Is there any help for me?

    I'm not getting an error message, it just finishes like it's done a dozen times now, except when i drive nothing has been changed. One of the things I messed up on is it shifts into 2nd at 4000rpm. It still does so I know nothing has changed.

    I still have the factory file, that's what I tried flashing back to.

    The only stock file I found in the tune repository gave an error that TCM not found.

    This is the messed up tune from a few days ago, and the original factory tune I saved when I first started.

    Another silly question; Is there a relearn procedure or a minimum time/distance that needs to happen or is it simply like a switch that's either this or that?
    I've never changed anything in the trans settings prior to this, but the changes to the engine settings have always been immediate.

    OK I got it, well I can drive it anyway. I read the current tune then copied/pasted the tables from the factory tune into it and then did a write entire. For some reason it took it this time. It surges in 4th gear like it's not locked up, so it's not truly fixed yet, but at least i can drive it now. Thanks for the help and any idea what I need to change now to get it to lock up.

    my 03 grandam surges in every upshift and its simply due to the momentum of the torque converter jerking on the next gear as it engages. if u really want to get rid of it go in vcm editor, select the transmission tab then select the shift properties and click desired shift time normal. the numbers are the amount of time it will take for the clutch packs to fully engage in a gear. 0 would be like popping the clutch in a manual car and a higher number wud be like slipping the hell out of a clutch. the performance table on mine was all 0s from the factory. heres what my factory tune looks like (not my current tune).
