We will review parameter support when A50 is back on the development agenda.

can you adjust it to lock up at your own editable slip rpm? Because for sledpullers or anyone with a loose converter will get slips about 1500rpm.
Yep, whatever slip limit you choose. I have seen mine lock with 1300 rpm slip, too high for me but it works!Quote:

mine is a 7766 os though, not a 1752. Is that gonna be a problem?

Any updates to this Ross or Cindy? Especially the TCC Slip limit table he added, since D5072 won't help if we are above 600 RPM of slip.
On my 05 5 speed I have issues with the converter being commanded to unlock any time I get tire spin rolling in the throttle from a cruise. Not during a shift, and it doesn't even have to be WOT - just rolling on the throttle from 50+ mph if the tires start to break loose at all the TCM will drop TCC duty cycle and unlock the converter - unlocking and flash stalling from 2500 RPM to 4500 RPM under power seems to be hell on converters. In 4WD without the tires slipping it will stay locked, only if the tires slip in 2WD. Also if you hit a dip in the road while accelerating hard and the tires lose contact with the ground just enough to get a touch of spin it will unlock then as well. With the BT lockup box in manual lockup it won't do it, I can roll into it from 60 mph and white smoke the tires without the converter unlocking; but I would like to be able to take care of it in the tune and not have to go into manual lock-up every time I want to accelerate from a roll when the converter is already locked.
Sounds like you are experiencing the ALLISON traction control feature kicking in. I know mine does it even on small tunes. When I logged all of the trans parameters and played the logs back I noticed a PID for traction control and it would go active everytime the tires would break loose when I got on it. If the tires broke loose from the start it would lock up like normal, but if they break loose when your moving the TCM would freak out and go into this traction control mode. Mine will even defuel when it goes active. This is on an 01 OS. Never bothered me much as I have no business breaking the tires loose at 60 and drifting a BURB. It would be REALLY nice to get the added lockup tables though. I'm tired of mine going to 3100-3300 and just sitting there until it finally locks at the top of 3rd gear.Quote:

Any new news for the 5-speed TCM being released on a public release? If anyone has got it to work I would love to get one of the files so I can test it out on my truck...
This would be a huge huge huge help also. What weird is that my 05os has the table as 3*17 and another 05os (sequence 000000 downloaded from holden crazy) has the same table D5072 at a 17*3. Im also assuming the cell values should have units of psi/second as the cells are defined as ramp rate. So a greater engine torque requires less time slipping to increase clutch life?Quote:

It has been quite a while since there was an update to this thread. When should these features be released? Surely, someone could enlighten us with a ballpark release date for both A40/50 and AL5?
Thanks and please understand that we appreciate the hard work of all - even the OP!
The issue was for the late AL5 and A40 only (as far as I am aware).
The update is done, but, we are going to release the A40 updates with the A50 programming enabled too, planning to have that done by this month or April.
Cheers
Ross
The issue is with ALL of the ALLISON TCM OS's. They ALL suffer from this slip limit hurdle(some worse than others).Quote:

The A40 as an example, we didn't define the table correctly, we said there was only 3 columns, not 5 like there is, that means you are not seeing the rest of the table. The changes we made are the same as what the original poster made, we've fixed the table so the entire thing is shown (5 x 17), we also have the axis points so you can change those too (see the attached pic).
Off the top of my head the AL5 was always a 3 column table, not 5.

Ross,
You're focused on the table. Everyone else is focused on the magic 625 number. Read the thread through that lense and it's clearer what's meant. No al5/a40/a50 tcms lockup consistently with big power without that edit.
Nick
Ok, well that single parameter became a small 3 value table in the A40 (at lest the OS's I checked).
If we include both the 'fixed' 5 x 17 table and the slip table are we on the right track?
Cheers,
Ross
Attachment 16473
P.S - Yes those temperature values are correct.
Specifically, what I am asking is whether or not AL5 will get the new tables and the slip limit adjustment. If so, when would we see the updates roll out?
I think your job here is done. Thanks Ross!
Ps-beav, yes- early April if I'm reading the right.
Yeah, I went back to re-read Ross's original post and realized that I misunderstood what he was saying. Rough day yesterday. :grin: I thought, for some reason, that they were not updating the AL5 but instead just the A40 and A50.Quote:

Will modifying this "slip limit" allow/cause the tc to lock in 1st gear?
No. Lockup in 1st is impossible with a 5 speed, and highly unreccomended for the 6 speeds. I still wish we could get the tables for TCC lockup at closed throttle. No matter where you set the tables, the TCM will unlock the converter at the same road speed when you let off the throttle. But I realize this request is beyond low priority as only a couple of us have asked about it(just would be nice for those like me who have 3.42 gears to be able to keep the converter locked at 55 when I let off the throttle. Gets really annoying having it unlock at 56 everytime I let off.).Quote:

The slip limit being solved is great, though! I'm awaiting this update anxiously.
Awesome job, thanks Ross!!
One other question....have you been able to find the table that specifies a force-unlock during a WOT downshift/kickdown? All TCM's do it EXCEPT the 04.5-05 LLY 5-speed. Like, if you are cruising on the highway in 5th locked up, floor it to pass someone, TCM unlocks TCC, then downshifts...then relocks. LLY TCM cal just downshifts without the unlock-relock dance.
Ben
Why "impossible"? Some thought that the 600+ rpm lock limit was impossible too. Now I'm more curious than anything else. Not sure why anyone would really need to lockup in 1st other than for the sake of fun (and danger for that matter).Quote:

Its a hydraulic limitation of the 5-speed valve body....it has nothing to do with tuning. You cant "tune around" a blocked off fluid passage in the valve body casting.Quote:

What he said. There is no getting around a built in limitation except for swapping in a 6 speed valve body(and that opens up a whole nother can of works to contend with). For a 5 speed lockup in 1st isn't going to happen. People have manually done it in 6 speeds, but all of the reports I have read from those who have done it advised against it.Quote:

Dave, the file was made available a couple of weeks ago in this thread http://forum.efilive.com/showthread....13-Cruze/page2Quote:

Attachment 16521i always thought this until i stalled my engine by having the TCC locked via the scan tool DVT controls and coming to a stop at a stop sign. i was driving slowly on some back roads experimenting with the DVT controls and had set the TCC to locked. when i came to a stop sign i pressed on the breaks and i could feel the engine bogging down and trying to maintain RPM. i was baffled as to what happened until i realized i had the TCC turned on.Quote:

i dont know how to explain this but it seems to contradict everything i have read. any explanation?
attached is my stock 5 speed tune
thanks Jason
So is this a go for 5 speeds????
From what I understand, yes.Quote:

I have no need for the A50 stuff, but the slip limit change sounds like a good reason for me to finally upgrade my software. It's getting really old not getting lockup until 4th gear.
Are you running al5 or a40? I run the al5 and I get lockup in upper portions of 2nd and up.Quote:
