2005 Volvo XC90 Question: transmission not shifting properly
Answer #1ZeeTech October 17, 2010, 18:44Master
There is a TSB out from Volvo to fix transmission shifting problems by updating the TCM's software.
You need to take it to a Volvo specialty shop who has DICE diag. system or to the dealership to have this done.
Here is a reference:
