I've just finished adding the highly requested transmission parameters we were missing. Currently I have the 2005 Mustang GT definitions done. I should be done adding these to parameters to all of the Mustang GT Autos we support this week, following that I will go back and get it in all of the Mustang V6 autos and F-Series as well.

Well done Eric!
Eric, Hp Tuners has the shift pressure tables to firm up the shifts on the 2004-2008 Trucks already.

OK, I haven't checked yet, just assumed it was missing.Quote:

Also there is a reverse band on the 5W55 Mustang trans, but what is a Low Reverse table referring to?
Russ Kemp
There is no table called Direct Clutch, but you did catch that I missed adding the Forward clutch. There is also another Reverse table I missed. I will find and add them today.Quote:

Eric, I still believe that Hp Tuners is calling the direct clutch a high clutch? As there is no high clutch as per my ALLDATA. Also under Boost & Stoke Pressures, there is a high clutch & direct clutch table. The forward clutch is applied in all forward gears, and the direct clutch is applied for 4th, 5th & reverse.
These are the apply components from my ALLDATA
Apply Components
Band - Overdrive
For component location, refer to Transmission.
During 2nd and 5th gear operation, hydraulic pressure is applied to the overdrive servo.
•This pressure causes the piston to move and apply force to the band.
•This action causes the overdrive band to hold the overdrive drum.
•This causes the overdrive sun gear to be held stationary through the adapter plate and the overdrive drum.
Band - Low/Reverse
For component location, refer to Transmission.
During 2nd gear, 1st gear and REVERSE operation, hydraulic pressure is applied to the low/reverse servo.
•This pressure causes the servo to move and apply force to the low/reverse band.
•This action causes the low/reverse brake drum to be held.
•This action causes the low/reverse planetary assembly to be held stationary.
Band - Intermediate
For component location, refer to Transmission.
During 3rd gear operation, hydraulic pressure is applied to the intermediate servo.
•This pressure causes the servo to move and apply force to the intermediate band.
•This action causes the direct clutch drum to be held.
•The intermediate band holds the intermediate brake and direct clutch drum to the case in 3rd gear.
•This causes the input shell and forward sun gear to be held stationary.
Clutches - Direct
For component location, refer to Transmission.
The direct clutch is a multi-disc clutch made up of steel and friction plates.
•The direct clutch is applied with hydraulic pressure and disengaged by return springs and the exhaust of the hydraulic pressure.
•It is housed in the direct clutch drum.
•During 4th, 5th and REVERSE gear application, the direct clutch is applied transferring torque from the forward clutch cylinder to the direct clutch drum.
•This action causes the forward sun gear to drive the pinions of the low/reverse planetary carrier.
Clutches - Forward
For component location, refer to Transmission.
The forward clutch is a multi-disc clutch made up of steel and friction plates.
•The forward clutch is applied with hydraulic pressure and disengaged by return springs and the exhaust of the hydraulic pressure.
•The forward clutch is applied in all forward gears.
•When applied, the forward clutch provides a direct mechanical coupling between the center shaft and the forward ring gear and hub.
Clutches - Coast
For component location, refer to Transmission.
The coast clutch is a multi-disc clutch made up of steel and friction plates.
•The coast clutch is applied with hydraulic pressure and disengaged by return springs and the exhaust of the hydraulic pressure.
•The coast clutch is housed in the overdrive drum.
•The coast clutch is applied when in manual 1st and 3rd, 4th with OD cancelled, and REVERSE positions.
•When applied, the coast clutch locks the overdrive sun gear to the overdrive planetary carrier, thus preventing the one-way clutch from overrunning when the vehicle is coasting.
•This allows the use of engine compression to help slow the vehicle and provide engine braking.
One-Way Clutch - Direct
For component location, refer to Transmission.
The direct one-way clutch is a sprag-type one-way clutch that is pressed into the center shaft.
•The direct one-way clutch is driven by the ring gear of the overdrive planetary carrier.
•The direct one-way clutch holds and drives the outer splines of the center shaft in 1st 3rd, 4th and REVERSE gears.
•The direct one-way clutch overruns during all coast operations and at all times in 2nd and 5th gear.
One-Way Clutch - Low/Reverse
For component location, refer to Transmission.
The low/reverse one-way clutch is a sprag-type one-way clutch.
•The low/reverse one-way clutch holds the low/reverse drum and low/reverse planetary assembly to the case in 1st and 2nd gear.
•In all other gears the low/reverse one-way clutch overruns.
One-Way Clutch - Overdrive
For component location, refer to Transmission.
The overdrive one-way clutch is a sprag-type one-way clutch that connects the input shaft to the center shaft during drive operation.
•The overdrive one-way clutch transmits torque in REVERSE, 1st, 3rd and 4th gears, as well as in manual 1st manual 3rd and manual 4th gears.
•The input shaft connects through the overdrive planetary carrier to the inner race.
•The outer race is part of the center shaft.
•The inner race contacts the assembly of sprags, and wedges them between the inner and outer races.
•The wedging action causes the input shaft and center shaft to be connected.

In the stuff I added, it is all correct. What Alldata is calling the direct clutch is actually the high clutch. In Boost and Stroke pressures, I think the parameters named direct clutch are actually the forward clutch. Once I am done adding in the new stuff, I will go back and verify that it is name correctly to avoid confusion.Quote:

FYI, these parameters have been added to every 2005-2010 Mustang GT Auto now.
Excellent Eric, I'm currently tuning a 2005 V6 Mustang !
I finished 2005 V6 Mustang just a few minutes ago. The parameters will be in the software tomorrow morning. Re-download 2.24 and they should appear.
Ok, so in the Boost & Stroke pressures, if the direct clutch is a actually the forward clutch then what is the high clutch? I just asked a very reputable trans shop, and they also said there no high clutch on the 5R55W trans. And my ALLDATA info comes from Ford.Quote:

We have the ZF6HP26 here in australia and I'm having this issue with my own vehicle at the moment, the boxés seem identical inside. I'm currently running in the new box I built as I can't reset the adaptive learning with HP or my scan tools.
A few of the SCT guys have got them running well with the TCM tune but can't access that yet with HP
Eric you are awesome now it can help every buddy fine tune the 5r55
we also need some switches to not enter fail safe mode when doing a 4r70w swap on 2007 auto mustangs since you eliminate a input shaft speed sensor and other things it shoots fail safe mode i know you can do it tunning with sct, there is a bunch of people that use 4r70w on high powered drag mustangs
To make it work, you have to flash a manual strategy in. The equizzer software version must also match. That is not in the software yet, but I'll put it on the list.Quote:
