2014 4x4 sr5

Thinking of purchasing a used tundra but the km's are you 251k(155k miles). I read that around this mileage transmissions might start acting up, should I be concerned of the km's(mileage)?
Mostly all highway miles, price is approximately 7k cheaper then a comparable year.

 

I haven't heard of any tranny problems. As long as it wasn't used primarily as a tow vehicle I think the mileage should be OK.

 

Thanks for the reply.
He has the receipts on oil changes, only repairs were brakes and a abs sensor.
Do you think it would be wise to do a tranny flush or is that a concern?
Also has a kn aftermarket filter that I'd like to switch back to stock.....can't see how sucking hot engine air would be better than outside air.
