5R110 Guardian Transmission includes the following:

The GUARDIAN SunCoast 5R110 Transmission is our base 5R110 transmission. This is a perfect transmission for a stock vehicle that is used in heavy duty applications. This offers all of the current fixes for the direct clutch circuit, with our Patent-Pending No Walk center support. This transmission also has the new wide-load direct clutch pack. This is the perfect economical solution for our customers looking for a heavy duty towing transmission with no power adders.

Tales from the 5R110

The TorqShift 5-speed 5R110 transmission replaces the old faithful 4-speed 4R100 in the 2003 model year with the introduction of the new 6.0L diesel engine. The TorqShift design, in fact, has a total of six forward gears ratios; however, only five are advertised, with the hidden gear only being used in very cold weather. The five forward ratios are: 3.11, 2.22, 1.55, 1.00, andfinallyoverdrive is 0.71. The TorqShift also utilizes an optional 4th gear at 1.10, which is used in cold start conditions to aid in engine and transmission warm up.

With the TorqShift, once the Tow/Haul mode is activated, it can help increase driver control when towing large loads up and down steep grades. It will also minimize shifts and maximize the available torque. Upon descent, the tow/haul feature utilizes engine braking to help extend the life of the transmission and improves driver control.

The TorqShift was also Fords first attempt at adaptive control. The adaptive control shift function monitors the performance over its lifetime and adjusts shift times in real time to ensure consistency and compensate for wear. The TorqShift was also used with the 6.4L. This particular transmission was later replaced with the much larger and more robust 6R140 when the 6.7L PowerStroke was released by Ford.

Walking Away from the Center Support

The center support on a transmission is a critical component that could make the difference between success or failure. The center support acts as a stabilizer, just as our lower back and abdominal muscles support us. With the TorqShift being such a long unit, over time, the torsional flexing distorts the case, and the center support can sag and become displaced. The TorqShift relies on the center support to also apply fluid feed to the direct and forward clutches. When this distortion occurs, the fluid feed holes for direct and forward can become misaligned. This is especially true when towing heavy loads or under moderate-to-hard acceleration. This will also lead to premature failure and burnt clutches.

SunCoast has developed a new No Walk Center Support to correct this issue, which we include in this kit. We also go a step further with this and make a new Mag-Hytec pan standard to increase the rigidity of the case and reduce torsional flexing.

With this now being corrected, the need for the direct solid modification is no longer needed. We originally created this modification before learning about the torsional effect.

The 'Wide Load" Direct Clutch

The direct clutch pack has been a problem child for some time now. With the center support now being corrected, we move your attention to the most problematic area of the 5R110: the direct clutch. In the 5R110, the direct clutch pack has been the topic of so many discussions. In the beginning, we modified the direct clutch solenoid as a result of the fluid flow issues we were seeing and trying to compensate for what we would later find out was the center support walking. Today, many companies still sell these altered solenoids to try to correct a direct clutch issue. We have alleviated this with our new no walk center support.

The direct clutch pack is still one of the most abused clutch packs within the transmission. The direct clutch pack is constantly subjected to conditions that can prematurely wear. To alleviate this, SunCoast has developed our new wide load direct clutch pack. These new clutches are not only made from our SunCoast SCZ carbon graphitic material, but also a larger, wider clutch.

Making the clutch wider effectively increases the mean radius of a clutch, which in turn increases the torque capacity of said clutch. What this means is the larger the mean effective radius, the more torque load capacity the friction plate can handle.

This new wider clutch is also combined with the new wider steel and new wider apply plate. This combination, along with the new and improved No Walk center support, makes this the most loudly engineered kit on the market today.

Mean effective radius is the distance from the theoretical center of the friction plate to the center of the friction material. What this means is the larger the mean effective radius, the more torque load capacity the friction plate can handle.
