That was most likely the xmsn "learning" how you drive. As for me, Id LOVE to have the 10 speed, MUCH easier to stay in the desired RPM range.I am happy with the 10 speed as well. I had some surging going from 2nd to 3rd early on, but it smoothed out aftera few hundred miles. Love the way it pulls the toy hauler.
Good lord, why does everyone think that since Ford and GM collaborated on a 10 speed for 1/2 ton trucks that this is the same one they put in the HDs?Looks like ya'll can thank Ford for the 10 speeds ya'll are loving so much 🤣😂
I wouldn't be so sure about that. When Mike L speaks transmissions you listen.Why? Ford had nothing to do with this HD trans.
1/2-ton 10spd is different from the HD 10-spd.....which was also a collaborative effort with Fjord, sharing the cost of development....with some input from Allison.There's a video where the engineer who was in charge of developing the new Allison CLEARLY states this. I'll see if I can find it again.
GM couldn't make up their mind if they were going to use the 9 speed Alli or something else. The 9 speed is shelved over at Allison and don't know what they are going to use it for. I think GM and Ford decided on the 10 speed that they built together and just made it twice as big. Ford took the lead on this development and my buddy at Allison changed the valve body to his specs.
So far it looks like TCM tuning is going to play a big part for this trans. A new pump and valvebody might be a big part of every build. Too soon to tell. I just ordered a stand for mounting this monster.

I was trying to find that one as well, but I couldn't remember which forum I read it on haha. Needless to say I need to stay busier at work.
