I have noticed a transmission "kick" when shifting from 2-3 and 3-4 when towing my 12000lb fifth wheel. I know there have been a number of TSB's and flashes available for various transmission issues and I was wondering if i would benefits from any of them. I haven't gad any other issues and love my truck. The birth date my truck is April 2010 so it is an early production one and currently have 13000 miles on it. Thanks for your advice in advance.

 

I've had my truck flashed twice now, runs awesome after that for a couple weeks then its back to the harsh shifts...does your truck shift hard when your not towing?

 

Seems to shift just fine when not towing. I was worried about a new flash creating more problems that I didnt want.

 

Several threads on the issue lately, mine goes in Monday I will let everbody know what they do.
