Had the TCM reflashed to the 5.3 TB calibration, trans shifts great, however I'm not able to make the cruise control work, anyone else have problems with that??

I've been having this exact issue. Looks like I might have finally found a solutiowith this threads help. So I have a 2002 S10 with 24tooth LS2 swapped and 4L60E i am running a 06 TBSS tune(and pedal... Dunno if it's different than the 5.3 trailblazer pedal) I have the P0717 code obviously since the 2 extra wires aren't there on the connector for the ISS signal. I get highly erratic shifts. ( and awful gas mileage which I believe is due to this) will I be able to switch to the 5.3 tune and my pedal still function and the P0717 code go away for good?
