Tranny shifts diff. after latest flash

I have a Job#1 08 Lariat CC 6.4L w/Auto/ After the most recent flash, my transmission wont shift into overdrive until I hit 50 mph. Before the flash it would. Has anyone else noticed this? It's almost like the Tow/Haul Mode, it simply will not go into overdrive until I go 51 mph, and I know for a fact that it did before.Ive got 35799 miles on it, and am just wondering if anyone else has noticed a difference in the way their tranny changes gears afdter the flash. Ive put over 500 miles on it since the flash, so IF it was because the tranny was relearning shift points it would be well done by now. Any info would be appreciated. Thanks

Sounds normal. Mine does this too. I believe that the correction was made to keep the fuel burning cleaner and reduce dpf regeneration. Possibly something to do with the egr as well.

Get Spartan, and fugetaboutit But seriously, I noticed the same after my latest flash as well. It's kind of annoying, since I'm forced to cruise around town at just under 50, but it's seems to do much better with the regeneration garbage...

Thanks guys. Its good to know someone else's is acting the same way. I know the "gear fast, run slow" technique is used in cat engines to keep them running longer, and that lugging a diesel isnt harmful, and is actually good for it, but I can see your point. Thanks for the info.

You do not want to be lugging the engine it is very bad for it.

Mine will shift at 46 mph if I am not accelerating. The engine is not turning up too high at low speed so I don't really want it idling along at 40 miles per hour in 5th gear. My opinion is that nothing is wrong. Gas engines will shift out and then down shift when you accelerate. The truck performs well as is.
