    There is one op system that hasn't had it added in yet.

    The 01 OS's don't have it mapped out, pretty sure all of the 02+ have it. If you're still not getting lockup in 2nd after you have changed the slip limit tables, go in to D5064, and lower the speed down for the lockup speed by 2-3 MPH or more, that should get you lockup. Even if you change the slip limit, you have to have the lockup speed low enough that there is a buffer between the 2-3 shift and the lockup speed, otherwise it won't lockup regardless of the slip limit settings.

    The issue he has is with a LBZ A40. I know which one he is talking about.

    actually all the slip limit tables in efi are referenced to the wrong memory location as i have discovered based on the fact that i know what table needs to be modified. when i load my working 1200rpm slip limit tune into efi it show me a slip limit of 625rpm, i can change my 1200 limit to anything i like and reload in efi and it still shows 625. its so easy, i dont know how they messed up the reference location.

    If you want to send me a .bin file and the address, I can make a CAX file so you can edit it in EFILive. Might help some other people out.

    I hope something becomes of this to help. I adjusted the table for my LMM and it reduced but did not eliminate the problem. Only Ben's lockup box actually cured it for me.

    Have you also lowered the lockup speed in 2nd gear? It doesn't matter if you raise the slip limit, if you are to close to the lockup speed in that gear, the TCM will over ride lockup until the shift is completed. I think this is the issue alot of people are running into with no lockup even after raising the slip limit.

    There are also a few more speed related lock up inhibitors not in EFI. Two that dictate min enable disable and an base value minimum speed lockup can occur at. If those are not lowered, in most OS's I have come across, the soonest possible you can get the TCC to lock is ~ 20 MPH. Which is close enough to the 2-3 shift that it will 90% of the time lock immediately as it enters 3rd Gear. Without changing those, Ben's box will always lock sooner.
