AutoShifters

I have one and I don't like it at all. It is an '04 model with a clutch. It shifts far from perfectly, and really slams the gears when downshifting in a hard pull. It seems to burn clutches too.
I will be changing mine for a 13 speed as soon as I can.
I have gotten much better fuel mileage with 13 speeds too. I cannot see an advantage to the auto.

 

The autoshift in my 07 century likes to rev to 2,000 rpm before shifting, sometimes it won't shift at all and I have to do it manually. I think it is hard on fuel mileage since you really can't progressive shift. I have had it coast in slow traffic then when I hit the throttle it slams hard into second gear throwing me violently forward. It also likes to try and slam into docks when backing. Very tricky to softly finesse into a dock.

In short I prefer a 10 speed.

 

I drove one for 4 years, learned to love it EXCEPT in the winter. The slamming into docks and coasting in traffic can be minamized with a little experience. Just make sure it has a manual shift option and if the road has any moisture on it use it...

 

We have one (three pedal on '05 International 9400) and while I don't like it, most issues are because drivers don't drive them like they would a standard. Would you keep your foot in the throtle when shifting your standard? And even though the computer does some of this, if you have not lifted during the shift it is very hard on the clutch. REALLY hard in traffic and will heat up the clutch.

I would do a three-pedal if you do one.

 

I only have owned and driven 1 truck with an autoshift. It was a Eaton Autoshift Gen II with the 3-pedal set-up. I didn't mind it for a few reasons...

1- The truck was bought for about $5,000 cheaper DUE TO the autoshift
2- The truck ran great and the autoshift worked just like a std trans in the manual mode (in the AUTO mode it was terrible)
3- The main good point was that it never missed a gear and would always hit each one while loaded going up or down a steep grade, and while pulling a 47k load of caustic acid or jet fuel, it came in very handy.

That is all I know about them. Tho I do have a friend who has a brand new 2011 Mack with the MP8 engine and the mack automatic and he said that it is flawless and smooth and he will never buy another manual truck again. I have heard many good things about the new Mack's and am highly looking into them

 

How long have you had that 2005??? That is the same model and year I had owned.......
