I am not to where I can look at my programmer...............

[wmcraig]

but , are there any other ways I can tell which revision mine has. I bought this off ebay about 1 yr ago and it seems like the transmission slips slighty through every gear change. I mentioned this to a dealer in tupelo Ms and he said it needs to be revised but he wouldnt do it or send it in for me.......I saw that one of the changes made was to calibrate speedo for tire size changes, and I can do this with mine. Anyways any help would be Greatly appreciated. William Craig

I have an LB7 2003 GMC Duramax 2500hd, and its a predator programmer.

ok i got home and plugged it up and it IS revision 1.11. would there be any problems with the programmer that could be causing my weak shifting tranny, i took it out and now it seems to be shifting firmer than with it installed?????
