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 5 are advertised. The "hidden gear" is only used in very cold weather. The 5 forward ratios are: 3.11, 2.22, 1.55, 1.00, and finally overdrive is .71. The Torqshift also utilizes an optional 4th gear, which is 1.10, that 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 Ford's first attempt at adaptive control. The adaptive control shift function monitors the performance over its lifetime and adjusts shift times in real time to assure consistency and to compensate for wear. The Torqshift was also used with the 6.4L as well. This transmission was later replaced with the much larger and more robust 6R140 when the 6.7L Powerstroke was released by Ford.

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. We did this as a result of the fluid flow issues we were seeing, 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.

Moving forward 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 graphite material but a larger wider clutch as well.

Making the clutch wider effectively increases the mean radius of a clutch, increasing the mean radius increases the torque capacity of said clutch. What this menaces 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 make this the most loudly engineered kit on the market today.

This is our base recipe less new Ford "9C" transmission pump and all new solenoids that we use on every rebuild. The SunCoast rebuild kit is designed to give the end user an option to build a transmission the SunCoast way using our proven "SunCoast Recipe".
