No car should last 200K. It aint natural.
@The GhostYou obviously grew up with a little more money than me. I once had some relatives give me a 59 Olds that was sitting in their yard. I hitchhiked 50 miles to where they lived to get the car,only to find out I could start it,put it in gear,and smoke a whole cigarette before the transmission would even start to pull. Besides being a rust bucket,that is why they couldn't sell it. Nobody wanted to dump 5 or 6 times what the car was worth into transmission repairs.
So I went to the closest gas station and bought a bottle of brake fluid,went back,and poured the whole bottle into the transmission fill tube. You should have seen the looks on their faces when I put it in drive,spun dirt in their yard,and got some second gear rubber when it shifted into second as I drove down the paved highway. Drove that car for over a year before I just parked it because I had bought a better one,and never had a minute of trouble with the transmission after pouring the brake fluid in it.
I THINK what the brake fluid did was clean the clutches and maybe dissolve crud floating around in the transmission pan so it would stop plugging the openings,but I am not sure. I just know I had that problem with a 56 Olds I bought from a junkyard when I was on Okinawa,and somebody told me to pour brake fluid in it,and it worked.
BTW,my father put 220,000 miles on a 55 Ford V-8 he bought new. Still ran good when he traded it in,but was starting to burn oil.
