The slipping and hesitation have seemed to stopped thank god. And yes I'm wondering if my diligence In wanting to stay on top of things vs letting it be caused the transmission problems. However my last Chevy got a drain and refill at 200k and it didn't kill it. I don't remember ever saying I was only looking at new but even at a 3 yo large suv your looking at 35k. I keep my cars for a long time obviously but when things start to hit the fan they need to go.
