Mike, I mean no disrespect towards you as I think you are extremely intelligent when it comes to the Allison, but you admittedly know nothing about EFILive. I'm not looking for any secrets, but I have played with just about every table in an LBZ ECM and many in the TCM. I have not seen any that have a big effect on shift quality either good or bad. As I stated earlier, when my transmission was stock I was having a problem with a no shift at WOT and a nasty defuel when the truck hit the rev limiter. I was even having a bit of a problem with it after the trans was built. I even went so far as swapping ECM and TCMs with IdahoRob and still had the same problem. The second time I had to replace the C1s, the shifting got better for some reason. I have no idea why, but it did. If someone wants to show me a table or tables that will change shifting and defuel on an LBZ, I would love to be proved wrong, but until then, I have to believe that there is some other reason people who sell tunes are posting what they are.

Do you remember what I told you when you went into your Alli? What did you find? You wonder why it worked better? Slipping C1 will have an effect big time.
Your post made my point exactly. There is not much of anything EFI will do for your trans except give you the opportunity to screw it up.
The point that is being made here is fueling. This is where you are going to make a difference in your shift. Why are you guys so stuck on the TCM and the stupid B&M type shift? Those days are gone. Shifts should be smooth and quick. Hard shifts are tie ups.
Seems no one is getting this.
Yes you are correct that I have not played with EFI. Why would I? If I need a tune or a mod I have Tony, Pat, Guy, Chris to do it for me. Think there is someone better? Rob has helped me as well and Brayden also.
You srill can't do much of anything with the TCM. If you took the time to look at the operation of the Allison electronics you would see that there never will be much you can do.
