Auto tranny life expectancy?

Just curious what type of miles one can get out of the auto tranny's in the 3rd gen 4runners?

Mine is about to hit 167k and I have owned it since 163k. I got it from a Toyota dealer and do not have any service history on it. I do know that the PO changed out the T-belt at 95k, but thats it. It was a one owner too. I did a drain and refill when I bought it and the fluid was pretty clean and still had that sweet smell too it. I did another drain and fill about 500 miles ago.

I bypassed the radiator and installed a Hayden tranny cooler just because, no indication of the pink milkshake and the radiator appears original.

At times it seems to shift a little hard, but I had a reputable tranny shop drive it and he said it felt fine and described the shifts as "firm" which is okay.

Keep fresh fluid in it, and it's pretty much a non-issue.
 
Some live, some die. The general consensus is that they last for a long time, but some of us get unlucky.

My truck has always been well maintained. My transmission fluid was always clean and I developed the slightest "whizzing" noise in gear, which was the torque converter failing at 152k.
 
I got like 200k outta one, bought vehicle used at 156k, hard wheelin n being a kid I guess. Replaced with brand new one from Toyota dealer, and now used engine with 96k at 300k on body
