several weeks ago when i tried to reflash my truck 2002 chevy trailblazer (I changed the low the same as high oct and changed the EGR from 1000 to 5000) and my truck didnt seem to respond on gears D, 3, 2. Only responded on 1 and reverse.
I reflash back to the orginal tune and nothing worked. I send my truck to the trans dealer and the trans was fine. So i send it to the GM dealer. They replaced the PCM and reflashed the program. I already had reflashed to the latest updates before all of this happened.
The gear seemed to work except me trying to reflash the efilive tune telling me to liscence my program which i did twice and nothing happened. Here is one case similar to miny problem:

I shouldnt have deleted the file i used to reflash but there is one file i have that is similar, the only difference is the checksum was different from the one i used today.
I already send the blx to paul and just want get other help from other people those that have a simlar problem to mine.
