Just got home for spring break and noticed something funny with my AT transmission. I have a steep downhill driveway to my garage and when I back out the car seems to struggle coming up the hill. Feels like Reverse clutch isn't staying fully engaged/ it's slipping. Car runs perfectly fine through all other gears. I was planning on changing the trans fluid soon so what I need to know is how much trouble would it be to repair the gear clutch? Is it a tedious job on a cav?
