Ben are these available and ready to ship?

If anything, the lockup controller could maybe even make your converter clutch burn up sooner...because without it, the converter slip speed will be above the TCC-slip-rpm threshold, and the TCM would inhibit lockup. When the converter is unlocked and "slipping", thats less power that is actually being input to the transmission. And you arent stressing the converter lockup clutch, because the converter is going to be unlocked.

I will never sell my lockup controller as something that will "help a stock trans". Will it "work" with a stock trans/converter and do the same thing as it will on a built trans/converter? (force lockup when the TCM is inhibiting it) Of course. But it is physically impossible for it to do anything that will increase holding power, and as I explained above, under big hp and an otherwise stock trans, it might even expedite burning up the converter clutch...

Thanks for the reply. I will hold off for a full build.

I'm sure they are. I've put 3 in and love how they work. Great product!

Has anyone ever tested strip times with the controller? Does it make the vehicle faster?

getting lockup in 2nd gear vs. 4th gear has allowed me to gain roughly .3 in the 1/4 mile

Those are the same results I've seen too.

Excellent, exactly what I wanted to hear.

I didnt need a lockup switch but i have my tranny locking the converter at 25mph wot and it helped me as well

Do you have logs showing input speed vs. turbine speed difference dropping to 0rpm by 25mph to prove this? Im just curious what magic trick you figured out, because out of the hundreds (thousands?) of 500+hp duramax's, yours is the only one that will lock on command....

Im not disagreeing with you and Im not trying to sell you a lockup controller, but ive been working on this issue for YEARS, and from what Ive found over the years, the only way you will get an allison to lock the converter with >500hp before the middle/top of 3rd gear is with an aftermarket lockup controller. Everyone who doesnt have a lockup controller merely "thinks" their converter is locking up properly when its supposed to (ie, when they have it set to lock in EFILive), when in reality, its not.

Ive lost track of how many people swear up and down that their converter locks up immediately under huge HP "oh, my truck hauls ass and runs quick times, the converter MUST be locking up! Otherwise it would be slow as hell right???", and when I finally convince them to log it, they are dumbfounded when they see that, at 60mph in 3rd gear, the "converter slip rpm" is still 600+ and the TCM hasnt even begun to trim on the TCC solenoid yet.

You can screw around with the tables in EFILive all you want; setting lockup to happen at 25mph in 2nd gear doesnt mean crap in the real world. There is an overriding table in the TCM calibration that will inhibit/ignore all converter lockup commands (ie, the TCC tables you can modify in EFILive) if turbine vs. input speed slip is over ~650rpm.

Until EFILive maps out that table, this issue CAN NOT BE FIXED IN SOFTWARE.
