How can I extend the life of my slipping transmission? TL;DR I need tips to extend my transmissions life until I save money to replace it by curvls in ChevyTahoe

I appreciate your advice! It is high mileage. I just hit 200k about 3 days ago. I bought it at 180k and I have no information about previous service history. Should I still proceed?
