4l60e shift issues

[kwwood1]

My 93 4WD Suburban (4L60E) will not shift into low or OD except when cold and usually forcing it to shift by manually moving the shift lever. I checked the voltage on all the solenoids at the computer and they all appear OK except the 3 to 2 downshift. I also shorted the solenoid pins to ground and they all "click" except the 3 to 2 downshift. Would this keep the tranny from shifting into low or OD? I am trying to figure out if I have a tranny problem or a computer problem????

The transmission is recently rebuilt and only has about 6K miles on it. Fluid is bright pink not burnt at all.

Well I finally found what was causing the shifting problem. The connector on top of the tranny could be rotated about 1/4" in the tightening direction when I rotated the connector it would shift correctly when I turned it back the tranny would go back into the "limp" mode. The truck has been OK for about 12000 miles now.
