> 24 hourFit 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.

> 24 hourWhile I dont have my car finished yet, this is the perfect replacement part to go with the B&M shift kit I added, better than stock and adjustable if you need it.

> 24 hourMy TH400 in my classic Jeep was shifting to early. I replaced this and used the screw to adjust this shift point to get the later shift I was desiring. Worked perfectly.

> 24 hourI 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.
