Greater than one weekFit perfect and works awesome to firm up the shifts on my 1975 jeep wagoneer with a th400 transmission. The factory setting on this is really close to what I️ wanted but I️ took it in two more turns to get it to hold the gears for a bit longer. Very, very happy with it.

> 3 dayI bought this to replace a leaky modulator on my 1976 GMC motorhome with a THM425 and 455ci Toronado engine. The shift points were perfect out of the box, no adjustments needed.
