What you have posted above is the opposite of what Carlton Bale, a Cummins/Jacobs engineer was posting in a long running thread several years ago.
Cerberusiam, you are entitled to your own opinions but not your own facts. Facts are facts and are recorded here.
Harvey, take off the rose colored glasses when you read. :-laf AGAIN you partially read one or 2 postings, draw the wrong conclusions, and mis-represent YOUR assumptions as fact.
I hate to burst your bubble but the late 04 and 05 units I have had apart have a thrust washer that is perfectly capable of handling reverse thrust. Where you found anything that says definitively they do NOT is wrong.
Even IF they had the older style washer in no place or so many words does Carlton EVER say the transmission will fail becuase of said washer. He clearly stated the POTENTIAL for failure was there on the test truck but NOT with any certainty when and if it would fail in normal use. They ran those trucks up and down grades and put the equivalent of 10 years use on the EB in a space of weeks, pretty sure the control group and placebo wasn't ther ein the test. :-laf
As for the 04. 5-05 Carlton clearly stated the reason Dodge would not certify it was because they could not absolutely guarantee the transmission downshifts and lockup would work correctly all the time becuase of the inability of the current programs to handle ALL the required programs. They NEVER released an upgraded program because it was NOT in their BEST INTEREST. Dodge is in the business of selling trucks so of course their recs will reflect that.
What Dodge does and does not authorize for use under warranty is frequently no problem to accomplish and use in the real world. Same as programmers, Dodge won't warranty the use of them but they are a bona fide add on that used correctly enhances the vehicle.
I clearly stated that the ECU's were not capable and an aftermarket controller would need to be used plus some upgrades would be a good idea. Its not an opinion its FACT becuase BD, PB, and ATS all have controllers that work quite well on an 05 and contrary to your opinions they don't self destruct at the slightest use.
Instead of regurgitating your misinterpretations of one or two high points of a thread why don't you post some of these facts your so big on talking about. Let's see some FACTUAL studies with real controls and parameters that definitively proves that after xxx miles and using an EB xxxxx hours towing xxxxx weight these transmissions will self destruct and fail because the thrust washer fails, the ECU doesn't lock the TC correctly, etc, etc, etc.
What DOES exists is 10 years of experience that says an ED does work fine IF certain things are addressed. Believe what you want but your opinions are no more persuasive than any other argument without something to back it up.
