Tiptronic A8600-102 5HP-19 Trouble

[Sirius]

Hello, Tiptronic A8600-102 5HP-19. I have a 1998 Automatic Boxster. It’s been sitting for 2 years. Problems I’ve fixed, ignition, Brake switch, drains, battery, Transmission Fluid level and fuses and the engine runs good but, It will Not physically go into Park or engage the wheels in any gear. From the Tiptronic underside I can shift from I,2,3,D,N,and R but not Park. From the Shifter inside the car I can shift from D,N,R but NOT Park. It will start in Neutral and I have tested the Neutral Safety Switch and the brake switch and still have the same problem. I have inspected the gear shift selector and shift cable for interference or obstructions, they both look Ok. I tried to put it into gear by hand by moving the lever and neutral safety switch manually, but even though I can move to all gears except Park the Tiptronic gear box does not engage or move the wheels. Any help would be greatly appreciated.
