2004 F150 U7151 shifting problem
What shifting changes have been made in the 9r05 version vs the 9r04 version? I like the firmer shifts with the 9r05 but my transmission feels like it keeps slipping in and out of overdrive. I do not have this problem with the factory tune or the 9r04 predator tune. I am currently using the 9r04 version. Thanks.

I have noticed the same issue. I have requested to have 9r04 emailed to me so that I can go back to that one.

Same issue here with 9r05 ver. Anyway to get 9r04 emailed to me also?

My calid is RXAQ5B4

Mine is RXAQ3P4. Shifting is not as smooth as with earlier updates of the U7151.

It's been a month since I posted my calid. Is anyone looking into this issue?

I have the latest tune in my truck now. So far everything is good and the shifting is much better. The truck feels stronger too. I am currently running the 87 performance tune +2 degrees on the timing with 89 octane. No pinging. There are some extra cai tunes with this release also.
