Cant flashmy LB7 TCM after a change

[Madspeed]

So I am trying to mess with shift feel and I tuned the trans andwehn I try to load it it crashes and putsmy tcm into an unknown state. the only thing I can do is revert back to the origianla toon. wich I changed and renamed as well tried it and same shit. What Gives?

Are you full flashing or cal flashing? I've found that many times I have to disconnect my BCM to flash the TCM as it is pickier to accept a flash.

Both. and the only thing that works is after the screwup I can reflash with the factory tune. yea it says I amnot connected tot he V2 and then continues untilllis\t fails thenleaves the tcm in an Unkown state. maybe Email me at durramax@yahoo.com ? =0
