Sorry... Since DPC... LOL

What actually keeps failing?

Corb@CorbinShipping · Feb 12, 2013

Dont know yet. NONE of the same parts from the last failure are on this truck. To include the tuner... It was Spartan when the first one let go, but we traced that back to a faulty DPC TC. Then, tried IDP V3.03, and I misplaced 5th gear on the highway, and rode 4th for a bit, until I Ret to Stock,and reloaded another tune, now 53 MPH cruise control...... to free rev, then cruise shutting off, and coasting to a stop...

I have nearly the same trans in the 250, and I beat the hell out of it.... with H&S, and IDP V3.01 with a suncoast HD TC, and the turbos crapped out at 3 k miles, and the trans still handled everything the the new setup threw at it for a few days, and still doesnt miss a beat...

Wonder if something got corrupted when you loaded the 3.03?

InnovativeDiesel · Feb 13, 2013

I doubt you'll find it's in the tune. We've been running these trans tunes since the trucks were released. All of the 3.03 trans tunes are the same, with the exception of the new early lock program. That's the trans program most run daily, although the others work just fine.

With my truck, my SCT sometimes does not load the correct TCM tune with the preloaded IDP files. You should be able to notice though when you load xrace and race lock, that when your trans is shifting like a stock truck, something isnt right. Sometimes takes my TCM 2-3 times to accept the correct TCM tune.

When You notice the sct didnt load the right tune, does it say the right one is loaded on the screen, or does it show that the tune you loaded is the wrong one?? Does that make any sense, if not ill try to think up a way to re-word what I'm trying to ask..LOL LOL

Mine does this also. when switching files, I always re select what I want and no issues. Did extreme street/race lock to race/stock to stock/race to race/race one day/ morning. That was a pain. Just wanted race/race.

It says I select the correct tune. I check and recheck, still a no go. The TCM just spits it out. By the first shift you can tell and have to reprogram.

I do this also, I re-select and still does not work sometimes. Happens pretty much everytime I switch tunes and ya it sucks haha. I just want to get in and go race/race. Sucks when its stock TCM strat feels terrible. You know how it is

Well, I have yet to take the trans out, however... 5th gear disappeared for 4 miles on the interstate... It didnt forget to show up to work, or take a vacation, or delete itself. I returned to stock, and reloaded a tune, and it came back. So, the tuning had something to do here. Ultimately, we wont know for sure until we get the trans out and torn down. It will be out in a few days, and I will get it to Aaron's trans guy sometime near to his event in March.

Bit I am running the same TC that Jared has in his 800 hp sled puller. The same TC that Aaron has in his lifted crew cab with 35s, and NX that runs 7.8xx, the same trans that Aaron has in his Xcab that just ran 7.2xx... And I have nno where near their power, and I have not done one boosted launch... It drove from NC to FL to NM, and during that time, in TX, lost 5th gear somewhere, only to have in reappear after the tuning was adjusted... Not after a rebuild... after the tuning was adjusted... Maybe it was corrupted, IDK... We shall see...

Just asking here...

In my mind, if you were cruising along day after day and everything was tip top, perfect, perfect, perfect then all of a sudden at full power it went BAMMM!!! And sh*t was internally broken, I would think ehhhh, mayyyybe a bit much on the line or something in the tune.

If on the other hand it's scorching the fluid, I'd have to ask.... what did those shifts FEEL like??? Like, were the shifts always firm and quick no doubt.... or were the shifts, or at least one or a couple soft and spongy? Trans fluid doesn't just look like crap for no reason. It usually involves a long time with soft, sh*tty shifts.

How did the shifts FEEL?

If everything felt good, and shifted good, and the fluid is burned up, then you may have some sort of valving issue leaking fluid creating heat, or something in the pump, or regulation valves, or something stupid like a piston holding force against a clutch pack when that pack is supposed to be released, burning it up.

I would ohm out my trans harness reaaaaal well to make sure you don't have something stupid happening that's causing the trans to try and activate more than one gear at a time or something.

I'm just a guy reading a post.... but what you describe, if there were no soggy shifts beforehand... seems like a chaffed wire, or hydraulic circuit/mechanical failure causing fluid pressure to bleed off, or something to activate when it shouldn't, or dragging clutch packs with a stuck piston or something like that.

A person familiar with the inside of that trans model should be able to see the culprit on teardown. But maybe not.

Check your trans harness for shorting wire to wire, and wire to ground. Wiggle it all around good while checking.

Point being.... I wouldn't concern myself too much with the trans rebuild materials and process, nor the programming. I'd be looking at something wrong with that truck/transmission specifically. Warped valve bore.... chaffed wires.... cross-talking wires.... sh*t like that. The general trans build and programming scheme work. Your specific truck/trans has a specific problem.

Could be in the TCM itself. Got to love electronics

A lot of that is in my thoughts as well. However, the trans was not my original trans. It was a built trans from Aaron. And my factory trans worked great, with stock internals, and stock fluid for 130,000 miles, over 80 k tuned.
