    Thanks for your help and support fellas.
    Add Torque reduction, and speed up the shift times.

    Also I've found it helps for consistency to make your high octane spark table transposed onto the optimal timing spark table. Makes torque reduction more predictable.

    There are a few different PWN delete kits that help keep everything full and at the right pressure, I use a Circle D and you're correct it's like another Shift, mine doesn't slip at all once locked up.
    Yea it still has that.... did you install a kit like this?

    They are going to completely rebuild the transmission at no charge. Circle D wants to cut the TCC open and clean it at no charge.... So I just have to get it all ripped out and shipped out. Again

    Yep one like that, my Trans was low mile so I didn't require the oversize one, from memory it was a recommendation from Chris at Circle D!

    Get a list of parts they are putting (or rather have put) into the trans.

    This is tedious because Circle D will cut open the TC, thoroughly clean it, inspect it (check the one-way clutch), and reweld it back together...

    not to mention your effort in R&R'ing the trans.

    Shift kit typically includes one or more of the following:
    - color coded valve body springs,
    - upto 3 washers under the 1-2 accumulator spring,
    - 3rd accum hole (did I get this right?) drilled to a specific size in the VB separator plate,

    those things can give a clue.

    Got them to replace the tranny... Dont trust them any more... took it to a local shop... busted her open.... and guess what... no custom parts what so ever... just a Z-Pack and Billet servos.... No boost valve no nothing... :( ..

    Sorry for the delay.

    I have a local shop rebuilding it now..... Man my wallet hurts.
