Yes I would like to read what the differences are, I try never to post "are now slightly modified" without giving the source, because you know someone like me wants to know.....and all the members are alwasy curious about sources.....so what are they? I wonder why Ford would change them....seems strange to re-tool for a samll change!!!
As to where my information comes from "Super Duty/Excursion new Model Technician Training Manual"

Back to the original ?, I have experience with both trannies and both of them are awesome. I think the TS will do better mated to a gas motor than the Alli. It really freaked me out when I first drove a 6.0L and the tach climbed to 4500 rpm. I primarily drive a GMC with the D/A combo and when it is cold, then trans shifts at higher rpm's and is a little harsher. Once it is warm, it shift like any other trans and the engine defuels between shifts to keep the pull smooth. I like the grade braking feature on the Alli better than the TS under load. Going down a mountain road, the Duramax will spin up to 4500 rpm while holding the gear. The other thing I like is the reverse gearing. I think it is 7.86 to 1 and it makes backing up very controlled. Haven't got a chance to try the new SD yet, these opinions are based on an 03' GMC and an 04' SD.

I owned one of each. Both were smooth and reliable. I'd take either one. The TS wasn't as busy downshifting when pulling at interstate speeds but the 6.0PSD had more torque than my 01 Dmax did so that might have been a factor there.
The grade braking on the TS was far superior at first on my 03. I really liked it. Almost like having a jake brake. But it got stolen/reprogrammed by a flash and it was then inferior to the allison. I still don't understand why ford did that.
We also have an Allison 3000 6 speed in our 03 diesel pusher RV hooked to an 8.3 Cummins ISC 350/1050 and it's a smooth shifting tranny, too.

I am yet to see any manufacturer not program around issues.
E.g. Sequential shift manuals that automatically upshift at cutout or before is a fine example.
Its a lot better to disable a function, take away a little bit of customer satisfaction, and have transmissions that are super reliable.
The Torqshift is a VERY strong gearbox, I have only heard of failures from people running silly amounts of power and Torque through it (Matt will attest to this).

I just do not see how ford can improve anything if they disable engine braking in 4th and 5th gear?

I just traded an 03 chevy 3500 with the duramax-allision combo in it. I think the allision may shifter a little bit smoother, but overall i like the torqshift much better. It does not hunt for gears all the time like the allision did when i pull a 14k trailer. By the way i am comparing this to an 04 f350 w/ 6.0 and torqshift.
