How did it perform? Watch the video, dummy!
So what makes the DieselSite transmission different? When you receive a completely built transmission you don’t see all the hard work and design that goes into them. All DieselSite transmissions come standard with direct and forward clutches built with 120 percent of the OEM clutch surface, a coast clutch upgraded with 200 percent of the OEM clutch surface area, a custom spiral snap ring, and a fully cut snap ring groove to hold up to exhaust brakes. There’s a whole host of other improvements DieselSite makes to the 4R100. Every single clutch pack is measured and set to exact clearances; every unit is within .003 inches. They have Torrington bearings throughout, a new output speed sensor, transmission speed sensor, transmission range sensor, and thermal bypass valve, as well as high-energy 850-degree frictions in all forward gears (including overdrive), which no 4R100 has ever had. It’s a DieselSite exclusive! Finally, there are full thickness steels for maximum heat transfer from clutches; a custom in-house built valve body for shorter shift duration which give firmer shifts and longer clutch life, and every remanufactured part is run through their de-burring machine. It’s safe to say we are driving stress-free down the road in our 7.3L with DieselSite’s Legendary 4R100 4WD heavy-duty transmission.
