trans was rebuilt and upgraded slightly less than 30,000 ago. tore it apart to live behind 500hp 383 and NOS shot 100-150hp total of 600-650hp.

i used a prostreet kit from dana at probuilt automatics, that is gona allow my 700r4 to handle 675+hp. gona be running a 2900 stall as well. heres the finished product!

When i tore it apart i was told to rip out checkball capsule in the end of the input shaft so increase flow to the tq converter to help with increasing lock up pressure. Has anyone done this or had experince with the checkball capsule being removed and how the tq converter locked up? My tq conveter before the tear down didnt feel like it was locking up... when i pulled it apart i realized the connector for the TCC selenoid had one wire in the wrong hole in the plug. Im not sure how someone who builds transmissions could have totally changed the individual wires in the plug and not known about it.

anyway... anyone without the checkball in the input shaft for TQ converter lockup? should i leave it empty or should i put it back in? experiences? anything?
