i took my 06 in for service today and gave them a list of issues. on the list, i had:

- occasional white smoke during starting and accerlation
- tranny seems to hunt at times or shift irregularly

i told them that TSBs 18-003-06 and/or 18-05-06 might address the above problems. they found TSB 18-041-05 and said it addressed both of the above problems. the work performed said "flashed the PCM to the latest number".

i've heard that TSBs 18-003-06 and 18-05-06 are also "MPG" flashes. since i had the PCM flashed to the latest, does that mean i would also get the "MPG" update? i am wondering if TSBs are just "diagnosis" and they always give you the latest PCM flash, which covers all TSBs to date?

just hoping i got the "MPG" update today which was one of the things i wanted.

 

I had the tsb 18-003-06 done to my rig and it helped the MPG.... The TSB 18-041-05 is for a 2005 model thats the way it was explained to me
TSB 18-041-05 ....??!!!

 

i think -05 is the year for the TSB and not year of the truck.

18-041-05 info

 

any TSB and PCM experts out there that can answer my original question?

 

They installed the latest and greatest flash(software update) that D.C.had to offer for your truck is how I read it and thats how it works.
