Volvo Repair: Transmission, volvo s80 t6, volvo s80

Question
I have a 1998 Volvo S80 T6 with 168K miles and live in Winfield.  The "Transmission Service Urgent" message appeared  the other day and the car would not shift out of 3rd gear.  The dealer said the only solution is to replace the transmission (the original trans was replaced at 68K).  My questions is this; is there any other alternative to replacing the transmission,.... again?
Thanks,
jjp
