Yeah, it's weird. You let off the brake, you have to smash down on the foot-feed to make it go. I had a little trouble myself, when I backed into a door. I was either backing up too fast, or not moving. :lol:

 

I don't like the full auto's whatsoever. The centrifigal clutch works fine with a loaded truck, but empty is horrible. Bobtail is even worse. I thought I was going to rip the 5th wheel off the trailer or kingpin off the trailer when I was hooking up. Sat there revving to get the clutch to engage, and when it did, it was all in at full speed.

Plus, with having a pedal, if you break free on slick roads, you can still hit it to let the truck freewheel to regain traction.

 

I didn't have any problem with the Mack, the only thing is, you better remember to put in neutral before you start dumping!!

 

A "full auto" such as an Allison has a torque converter and is easy to control when backing up or inching forward, just like a car automatic.

The "full auto" you're referring to is actually a manual trans that has computer controlled shifting, and a conventional clutch that is also computer controlled depending on throttle position. It's basically an "autoshift" without the clutch pedal.

They are different in that you can't idle back, you have to work the fuel. I thought it was a little harder to back an auto because of this.

 

drove 3autos and didn't care for any of them, the first one had the clutch and that one was realy tricky if you had to stop on an incline, getting started foward again was a PITA, the last 2 didn't have a clutch so it was as simple as just giving it plenty of foot before you let off the brake but I never felt like I had as much control over them as I did my 9 or 10 speed manuals.
