Classic typical TR issue.
Let's try at first with removed hydraulic pressure and to remove snake shaft and reinstall in corect direction. TR should be extended during this procedure, pin installed in module. After assembly all, pressurate HYD system and retract TR with hydraulic power. TR will goes to the lock and indication lights goes out. Operate several time TR with normal hydraulic operations. 90% problem will solved.
