Anybody have issues with the ten speed, with the 3/4 shift. I found that t s b for it, but it is expired.The dealer said no longer valid. Waiting to find out if I have the current software update for the transmission. It's a very, very mild delay. I think ford calls it shift flare or delayed engagement. 34,000

 

Yup. I think everyone does. I was told it's the torque converter unlocking. It's more pronounced with light throttle. I don't understand why it only happens with the 3rd to 4th or 3rd to 5th shift

 

mind is more pronounced. What I have my foot into it when I let it run through the gears if I give it soft throttle, it goes from third to fifth. What if I put my foot into it hard? It runs through all the gears. And that's when I feel that delay from 324

 

Transmission tuning corrected this for on my truck. Before that I got so tired of it, I would start to anticipate it happening and when it did I got even more frustrated.

 

Who did you use?

 

i guess my concern does the transmission Have a mechanical issue, the start of one or is it a computer tune related

 

Put it in tow/haul mode and see if it still does it. I used ASAP Calibrations. Alex is his name.

 

This is interesting, in my 2022 F550/6.7, 3rd never seems to get to TC lock, if I'm going down a hill in 3rd (locked everything above out) and let off it just idles down, then if open up 4th, it'll rev tf up and speed up before it shifts to 4th, I've played with using TH, no change, I usually drive it in deep sand/snow as it's a little bit "peppier" than the other modes, but the 2-3, 3rd and 3-4 shifts are wacko
