prob #1 - after getting my transmission flushed for the 80,000 km (as per the GM recommendation) about 500km ago, once the car is running for at least 30min and is warmed up nicely, the transmission hesitates slightly when shifting from 1st to 2nd and 2nd to 3rd, and seems to jumped forward a bit when it hits the gear. Is the transmission flushing a cause of this or is it something else?
prob #2 - unrelated, i have noticed a slight wiggle with the rear end when going over small bumps at speeds between 60km/h and 120 km/h (35mph - 75 mph). What can I check to see whats going on there?
Thanks
