The TCS is inside the transmission, not very accessible.

Your transmission will most likely need rebuilt. My GT wouldn't shift into 3rd or 4th last august and I had to get it rebuilt.

My GT wont shift into 3rd or 4th either, I am just opting to replace the transmission rather then rebuild. But you should be able to access the TCS by removing the side Cover of the transmission.
