02 s60 tranny slip

I have a strange problem on my awd turbo s60, whenever the car is started and then put in drive, the shift from 1st to second gets a minor grind on one shift only and only one time until the car is turned off. I have tried starting the car and going in reverse , it will also give me a slight grind/synchro problem, just for a second and then never again, unless of course I turn the car off. I have tried starting the car and then going to manual mode, placing the car in 3rd, and then driving it. Same problem. I would say that this occurs 60% of the time. I have tried replacing the fluid with synthetic mobile, flushing the full 12 quarts. I tried the IPD valve servo cover, yet to no avail.

When I changed the fluid I expected to see all sorts of metal flakes but there were not any. I assume that there is some sort of vacumn/pressure switch that may be causing t his problem. There does not seem to be any difference whether the car has warmed up or is diven cold. In addition, it does not make a difference whether it is driven hard or conservative. Does anyone have any ideas?

At 123K, probably not

The car only has 103k on it. Do you have any ideas? Several people have just told me to live with it.

how was the fluid before you changed it?

Install a magnefine filter just for extra protection.

that minor grind you are hearing is just the ABS doing a test, it happens at exactly 12 mph after starting the engine.

Maybe you didnt read the manual?

Anti-lock Brake System (ABS)

The ABS system in your car performs a self- diagnostic test when the vehicle first reaches the speed of
approximately 12 mph (20 km/h). The brake pedal will pulsate several times and a sound may be audible
from the ABS control module. This is normal.

Also the fuel filler door will auto lock at ~10mph after refueling.

A tranny slipping would cause your RPM's to go really high and the car would barely move...
