My 1997 Legacy Brighton automatic is shifting a little weird. It has a slight hesitation between shifts and will sometimes downshift when it does not seem appropriate. I have about 155k on the car and it runs fine otherwise. It has a replaced motor and tranny at about 60k due to being sold to us with one tire a smaller size than the rest by Ch@rlie'$ Subaru in Augusta, ME. That was the last time the AT fluid would have been new. I just put a new (to me) exhaust on it and new o2 sensors and the engine runs nice and smooth.
I found this video that more or less exactly describes my shifting issue with the same car and a fluid change seems to do it.
I just called a Midas to get a price on a AT fluid flush and was told to be careful as the transmissions sometimes just quit on this generation of subarus after a flush. He said to let it ride.
I don't understand this but have heard it before. So should I not change the fluid? Maybe a bottle of the Lucas Slip stop stuff? Would something else remedy my sluggish shifting?
Any suggestions? I can drain and fill the fluid myself but thought a flush to be better and less wasteful/toxic. I definitely do not want my car to quit. Thanks for any help
