Well its fixed!!
The shift solenoid was bad, If you have a code 81, the 2-3 shift
solenoid will cause you to stay in max line pressure, no TCC lockup and
3rd gear only when lever is placed in drive.
That shaffer shifter I wont get to see since it is working.
You could ask them about it at B & W transmission Hampton VA.
They described it as a plugin to the transmission port and the device
controls and sets the shift points, diagnostic tests etc... right
inside the car as you drive around. Unplug the car computer and plug
this in. But I am assuming this is a diagnostic test device.
