Do you know if the pump slide spring was replaced with the sonax or some other mod to make it stronger that stock , The Pump slide with the stock sping can begin to allow the pump to colapse over 6000 RPM this can cause the line presure and volume capabilities of the pump to drop substaintially above that RPM this may cause delayed shifts, soft shifts, longer that desired elapsed time from command to actual shift.

 

i do not know but will ask in the morning
THANKS, Johnny
