2021 F150 XLT Powerboost
Howdy everyone! First post here but used to be active on 7.3 Powerstroke forums with my old truck.

I recently picked up a 2021 Powerboost with 30k miles and really love it so far. Some research lately has enlightened me in regards to making the 10R smoother shifting. Currently, it’s a rather hard 1-3 shift with all other gears being pretty great.

Is anyone here able to run an OASIS report for me to see if I need any of the TSBs done for transmission programming? Also, can I get TSBs fixed at any dealer or only the one I purchased it at? The reason I ask is because the place I bought it in NoVA has a “for life”program and I’d hate to put that in jeopardy by having a TSB done somewhere else.

Thanks!
