The Torqshift 5-speed 5R110W Transmission replaced the old faithful 4-speed 4R100 in the 2003 model year with the introduction of the new 6.0 L diesel engine. The Torqshift design in fact has a total of six forward gear ratios, however only five are advertised. The "hidden gear" is only used in very cold weather. The 5 forward gear ratios on the Torqshift, starting with first, are 3.11, 2.22, 1.55, 1.00, and a final overdrive of .71. The Torqshift also utilizes an alternate 4th gear, which is 1.10, that is used under cold start conditions to aid in engine and transmission warm up.

On the Torqshift, once the tow haul mode is activated, it can help increase the driver's control when towing large loads up and down steep grades. It will also minimize shifts and it maximizes the available torque. Upon descent, the tow/haul feature utilizes engine braking to help extend the life of the transmission and improve the driver control.

The Torqshift was Ford's first attempt at adaptive control. The adaptive control shift function monitors the performance over its lifetime, and adjusts the shift times in real-time to assure consistent shifts and to compensate for wear.

The Torshift was used with the 6.4 L as well. This transmission was later replaced with the 6R140 when Ford released the 6.7 L Powerstroke.

The 5R110W Torqshift transmission can be a very stable and reliable transmission if built correctly. Here are some of the improvements we make on all of our competition Torqshift transmissions:

Center Support

The center support on a transmission is a critical component that could make the difference between a successful vs. unsuccessful transmission build. 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, causing the center support to sag and become displaced. When this occurs the center support allows the fluid feed passages to no longer line up for the forward and direct clutches. This will cause shifting issues along with premature wear and burnt clutches.

At SunCoast each one of our units receives a new custom redesigned center support that corrects these issues. We go one step further and add the deep cast aluminum pan to add structural rigidity to the unit. This is an absolute must when delivering a proper functioning transmission.

Low/Reverse ring gear hub

The factory low/reverse ring gear hub is known for shattering into pieces due to the loads carried by it. SunCoast replaces the factory ring gear hub with a much stronger billet piece. This custom billet piece is designed and made using 4140 HTSR (Heat Treated Stress Relieved) billet steel and can withstand even the most aggressive right feet in the industry.

Low/Reverse on way clutch snap ring

It has been well documented that the low/reverse retaining ring "pops out" of the case groove, this causes slips in reverse and in most cases will lead to catastrophic failure to the case lugs. When moving in reverse, we have seen the pressure plate experience some radial movement within the case. This movement will walk the retaining ring completely out of its groove. SunCoast has a heavy duty retaining ring that is not only wider but much thicker as well. This new retaining ring will provide more outward tension than other available replacement rings. This new increased tension and improved rigidity helps keep the ring seated securely in the case groove.

The Valve Body

You can think of the valve body as the brain of the transmission. In a clutch to clutch transmission the brain is even more important than ever. A valve body that is improperly calibrated can create nightmares for both builders and customers alike.

On our Torqshift valve bodies, each one is custom calibrated to fit our customer's needs. The original design of the Torqshift valve body included five hydraulic pressure switches. Although these switches were never actually enabled by Ford’ or monitored by the computer, the early valve bodies came through with all five switches installed as dummy plugs to seal the hydraulic circuits. The later valve bodies have all the pressure switches, with the exception of the direct clutch pressure switch, which is removed. The locations within the casting are left unbored, to essentially seal this circuit. The remaining OEM direct clutch pressure switch in the later valve bodies is still not enabled, or computer monitored. With the excessive high pressure that is a frequent issue in these units, it is not unusual to find the pressure switches/plugs damaged. This will result in loss of shift solenoid control pressure and numerous shift complaints. SunCoast remedies this by replacing these plugs with a much better design with improved sealing rings to correct this issue.

With the potential damage to the shift solenoids, we replace and flow test each solenoid that goes in our Torqshift valve body. Each valve body is also vacuum tested to ensure there are absolutely no cross leaks across any of the hydraulic circuits.

Each Torqshift transmission that SunCoast builds also receives a custom calibration to ensure all of the customers needs are met.
