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.
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.
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.
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:
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.
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
ring gear hub
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.
on way clutch snap ring
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.
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.
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.
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.
transmission that SunCoast builds also receives a custom calibration
to ensure all of the customers needs are met.
