Custom Transmission Tuning for Ford® 5R110

SCT OEM Transmission Control Tuning

I offer OEM control system tuning with SCT for Fordcummins conversions, or even Ford diesel trucks with the original engines at an hourly rate of $60.00/hr.  I have used other brands of tuning software in the past and have found SCT to be the best software.  It was not the cheapest by far for me to buy, but it does offer the best value for the customer, since data logging capabilities are built into the SCT tuner and the software is so much better it takes me less time to make adjustments when compared to other systems.

Even 6.0 powered Fords can also benefit from custom transmission tuning- especially those with taller than stock tires or trucks with gear ratio changes.  Blanket speedometer or gear ratio tune changes help, but don't often zone in on the real issues involved with what you do with your truck.  Better timing of torque converter lockup, lockup in lower gears, and custom tailored tow/haul features are improvements that can greatly benefit the function of the 5R110 Torqshift.

For owners of 08-10 Fordcummins trucks, the option of using the factory tcm has been a risky one - there have been a few swappers that burned their trans up doing so, since the transmission control system is more complicated than the 6.0 systems, and does not calculate torque correctly with a Cummins under the hood roaring at wide open throttle.  In order for the transmission to work properly, the torque calculation needs to give big numbers and be tuneable- with this working properly the 08-10 5R110 will be prepared for the torque the Cummins will be giving it.  Getting it working right requires a few wiring tricks, and some tuning tricks as well. I'm still working some of the kinks out, but am able to get calculated torque to over 600 ft/lbs with most Ford calibrations.   One Ford calibration or "strategy" is particularly difficult to work with, so finding out which one you have is a good first step when planning what system you decide to use.

PCS TCM-2800 Transmission Controller Tuning Support

The new PCS TCM-2800 is a huge step forward and is now available to us PCS dealers, so the TCM-2000 is now obsolete and can no longer be purchased new.  I am currently working with two 5R110 customers with TCM-2800s so I am now supporting it as well for those who do not have any better option. This new controller has tow/haul (calibration b), and many updated features that I anticipate will make it a close rival to OEM controls in the near future.

Let me be the first to admit however that even though I have learned a great deal about this new control system already, I still have a good bit to learn.  There are tons more tuning parameters, and with that comes greater complexity.  

I'm going to do something with this that I wish I had done when I first started tuning and keep track of how many.

Legacy PCS TCM-2000 Transmission Controller Tuning Support

If you are using the Powertrain Control Solutions TCM-2000 to control a Ford 5R110 Torqshift transmission behind a Cummins and you are frustrated with how it's going, consider giving me a chance to help you.  PCS does not support the 5R110 application and has left that to us dealers.  As you may already know- the PCS TCM-2000 was the most popular* aftermarket system available for the 5R110 and there are quite a few in service.  It does work, but tuning the trans is extremely tough for those who are beginners- even guys that claim they know what they are doing may not, and make excuses for rough or slow completing shifts.  These type of shifts are common, but not good - and are caused by incorrect clutch to clutch tuning or trim adjustments.  If during the shift it feels like you are tapping on the brake, the clutches are binding.  If the engine rpm spikes up during the shift it is flaring. 

Adjusting the clutch to clutch parameters correctly requires studying a recording of the transmission data during a test drive, called a data log. Data logs are so important to the tuning process that I'll give you a friendly warning- if someone is helping you tune it without studying a data log they don't know what they are doing and could cause damage to your transmission.  Continuing to use a transmission that is not properly tuned can and often will cause damage to the transmission.  Since I first started working with the PCS 5R110 controller, I have made many improvements to how it works, and will continue to find ways to improve it.  The PCS TCM-2000 controller is very well featured, I strive to offer the very best support available for it.

Advantages the PCS 5R110 control system offers is manual mode shifting, full and "easy" control of line pressure, shift and torque converter lockup points, and fast calibration flashing. 

If you need tuning support, sending me a datalog is the first step.  Learn how to do a datalog and calibrate your throttle position sensor by watching these videos.

* HGM Automotive Electronics (Compushift) is advertising the ability to control a 5R110 with the Compushift II controller.  I have not tried one with a 5R110, and haven't heard of anyone that has yet.  If anyone out there has and can share a data log with me I can give it a fair review.
