Tip Failure

[porsche964guy]

1990 Tiptronic with over 200K miles. (daily driver)
Last week took a drive up the coast and when I got back I blew the cooling fan belt. Finally got it back home and not having time to do it myself I brought it to the local dealer, only because they were close. The next day my trans started shifting hard. So I took it to a shop to lift it to check the fluid level and it was good. By the end of the day it wont move in forward gears only in reverse. Any Ideas whats wrong or will I end up looking for a replacement? By the way the TIP warning light is on now! Any comments appreciated.
