Alot of the miles are interstate cruising at 75 I will admit. But around town its pretty much wide open about 90% of the time. It's been downshifted about 804376289 times. The fluid is getting rough looking and smelling though so it's only a matter of time.

 

mines at 111k... it did pop the line off bout a year ago... didn't notice til the truck started slowing down and i promptly pulled over.... that c clip just backed out...thought it was toast but still holding like a champ.... vette servo and my own tuning only... though the tb verter is starting to cycle when cruising..... new motor bout to go in and verter

 

same here. i bought the truck with 82k on it, and didnt know the service history, so i never changed it...
