It does to me. There was a previous debate on this subject and as far as I am concerned I now request that the fluid is checked and topped-up if required by my VX dealer, where the car is serviced. It needed topping-up last time. After some research online I couldn't find an equivalent to the GM specified fluid, even though it is doubtful that GM manufacture it. For peace of mind I insisted that the GM product was used and the dealer had it sent over from one of his other branches. By all means drain and change if you prefer, but make sure the correct fluid is used and not something where "that'll do" rules - it's not worth the risk.
In a past life I used to use GM oil and filters on my Omega and they were less expensive than the usual suspects from Halfords.
