Transgo 48re shift kit page 7:
Remove the stock pressure screw and replace with the kit supplied shim, washer, plain inner, and orange outer spring. Interesting, the kit does not call for 2-4 turns of adjustment on the pressure screw. I recommend the pressure is turned up at least 2 turns and more for more line pressure = more torque capacity on the whole transmission.
Transgo provide an upgraded clip, simply remove the plate and (3) T-25 screws:
Drilling out the port in the plate increases lock-up pressure, not sure why the 48re kit does not call for this step, I used a .096" drill bit:
I also changed out the shaft seal (from the transmission master rebuild kit) on the TV lever/rooster comb:
I finished up by installing the new lock-up & overdrive solenoids:
A picture of the DNJ upgraded governor solenoid and block, these won't be installed until the valvebody is bolted to the main transmission case.
