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.

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!
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... :( angry..
Sorry for the delay.
I have a local shop rebuilding it now..... Man my wallet hurts.
