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?

Any update on when this is going to be updated?

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.

The issue is with ALL of the ALLISON TCM OS's. They ALL suffer from this slip limit hurdle(some worse than others).

Does this mean that AL5 feature updates will not be implemented or just that they are not on the road map yet? Are the challenges with the AL5 and A40 resolvable or a lost cause?

[GMPX]

Ok, so I am confused now.
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.

Cheers,
Ross

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.

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



P.S - Yes those temperature values are correct.
