For HBarlow eye's only

[RVTRKN]

Read this, now that you have figured out how. BTW where are your remarks on the last time you were proved wrong. One example, Hydroformed frame ring a bell.

If you really intended this for Harvey's eyes only, you would have PM'd him. Since the rest of us are obviously going to read the post, be nice to know the technical point you are making.

HBarlow posted that I'm wrong, that there is no TCM computer for the 68rfe. Have to go for now, will chime in later.

Nice article but it has nothing to do with your earlier dumb claim that the transmission control engine torque management.

The article plainly states that "fully electronic control (of the RFE transmission) is accomplished by the TCM. " Where in that sentence do you see anything about the RFE controlling torque management?

And it goes on to state "the TCM can be a stand alone module or integrated with the Power Control module (PCM). " Where in that sentence do you see anything about the TCM being the transmission or part of the transmission?

It further states "The TCM uses data from various transmission and engine sensors to control transmission shifting. " Where in that sentence do you see anything about the TCM controlling engine fueling, boost, fuel timing, or TM (torque management)?

No wonder you post wrong information all the time. Apparently your reading comprehension is a bit lacking.

Perhaps I am unable to see your point in the above article. Please explain it if you wish.

THAT is a baldfaced lie and you are well aware of that fact.

You began this unfortunate argument by claiming in the G-56 girdle thread which anyone can read that the 68RFE automatic transmission controls torque management. Cerberusiam who clearly knows a lot about automatic transmissions stated that you were wrong and so did I.

Instead of learning from your mistake you tried harder by posting that a tech told you so. Your claim was still disputed.

Now you are shifting your position and offering something entirely unrelated as proof of your earlier wrong statement and claiming something entirely different.

I invite anyone who reads this and wonders what it is about to simply read the comments made in the G-56 girdle thread.

Read more here, then feel free to beat your head against the wall :-laf: https://www.turbodieselregister.com...7/228429-g-56-transmission-torque-girdle.html

 

[HBarlow]

This is one of his previous statements from the G-56 girdle thread. It is more clear to read the entire thread.

Not per my tech's opinion's on this subject, in fact they thought it was funny that we (TDR) are blogging/arguing/discussing about it, but they have confirmed that the auto does have TM, like all modern automatic transmissions, too include gas applications, to save the transmissions from the higher HP/TQ in the modern engines.

Wait. . this was an attempt to prove the trans controls engine tq management?? That's only a guess based on posts in this thread, and previous statements you have made. . The verbage you posted has zero to do with tq management...

 

[RVTRKN]

OK, the ECM makes the decision to manage torque, but the TCM sends the information to the ECM. As you read the sequence of operation of the TCM, it does tells the ECM the condition of the transmission to protect the transmission. Yes the TCM does not control torque, its the ECM that does this, but when and how could it know the condition of the trans? If it wasn't for the TCM, the ECM would be blind. The TCM makes the decision to send the oil through the valve body to the clutch packs, through solenoid operation, thus it has a computer that HBarlow refuses to recognize. The information is in black and white, now that we know he likes to read.



TM is controlled by the ECM, but makes its decision on the information provided by the TCM. The TCM also tells the transmission at what gear to run and what solenoid to operate.



"This design allows the vehicle to be driven (in limp-in mode) in the event of an electronic control system failure, or a situation that the Transmission Control Module (TCM) recognizes as potentially damaging to the transmission.

Except for this quote



"He may think the transmission has those magical properties but the automatic transmissions used in Dodge Rams DO NOT have an internal computer or other devise that is capable of recording information and making programmed decisions. "



The TCM does just that, and has adaptive memory.

It would be interesting to hear Marco's take on how torque management is accomplished. I may be wrong but since he writes software to limit/eliminate it, I will assume he knows how it all works.

 

[CUMMINZ]

For what it is worth, I have eliminated my torque management with my Smarty and my shift points and lockup times have changed for sure.

to hear Marco's take on how torque management is accomplished.

Torque Management simply limits low rpm fueling. The transmission (manual, auto, whatever) isn't telling the engine how to act or fuel. The ECM uses inputs (cam sensor, crank sensor, MAF, MAP, TPS, RP, etc) to pull a fueling value from the maps in the ECM.

Torque Management simply means that fueling tables for low rpm have a shorter duration. Eliminating TM means that a longer duration is used at the low rpm conditions. Of course, if you have the capability of changing the look up tables, you can set duration to whatever you would like.

How does the MOPAR 68RFE behave during shifts while loaded with a heavy trailer and with torque management deleted? Does it shift hard or still make the soft shifts?

Do you keep your foot in it or back out and paddle shift it manually?

He is playing with fire by eliminating (as much as Smarty allows) torque management. The reduced level of tq management he is running is never suggest for a stock auto, or for towing. The trans just can't handle the stress long... What does a built, or stock rebuild, 68RFE cost these days?

Wow, that sounds very expensive. The thought makes dollar signs roll before my eyes. Dollar signs followed by the numbers 1 0 0.

That goes double and triple for the 68 becuase it is severely under clutched. ANY bump in power at the wrong and no corresponding increase in line pressure will smoke the clutches in a hurry. You can't just change 1 thing, there are several changes that need to be made.



As for cost, how fast ya wanna go?

HB, It shifts like normal. I am not pushing it or trying to accelerate any faster. I simply am looking for an increase in fuel economy and I have it with these settings. I am running this tune on flat ground and not in the mtns.

I understand ATS is in the process of producing a unit called "Co-Pilot" that will plug in to the wiring harness of the transmission on the 68RFE transmission, which will not only increase the line pressure, but also allow one to change the line pressures for differing operational situations. As I understand, the holdup is the manufactureing of the plugs.
