Manual vs auto has nothing to do with it. Just dont sit there and roast the tires in 1 spot.
All of the manuals have a creep mode that can be enabled. It's exactly the same as slipping the clutch on a manual.

I only ran an auto for several months, don’t consider myself an authority on them. Basing my opinion off the little experience I had, and the fact that a friend of mine does mobile welding repair, and he replaces dozens of sets of landing gear every year. Said it’s always an auto that tore it out, guys can’t feather it near as well... Local outfit he has replaced quite a few sets for started switching back to manuals again, said they blame the transmission for a lot of their trailer abuse.

Desk jockeys who dont know how to properly spec a truck and drivers who dont understand how to properly operate it aren't the fault of the equipment.
If you were building a house and all your nails kept getting bent over sideways would you blame the hammer or the person using it?
Theres a lot of "old school" guys in the industry and a lot if under trained drivers who think the throttle on an Auto truck is an on/off switch. If they are programmed wrong based on the order thats how they can be. If you actually spec and program them properly they can be feathered just the same as a manual truck.
I've been running autos for the last 9 years now. 6 years with an Allison and now 3.5 in a Detroit DT-12VX. I hook up to my loaded mechanical neck trailer in soft ground all the time with no issues spinning the tires or slamming the king pin. Just have to learn to left foot brake when hooking up. Feather the throttle to pick it up and then hit the brakes as soon as its on the fifth wheel then slowly back into the pin.cke, Albertaflatbed, beastr123 and 1 other person Thank this. -
Please don’t crucify me:
it will be a 2025 Kenworth W 990. it will have the Lyft axle and tires steer tires rated at 20,000 46,000 just for the drives I think. it will be double frame and I’m not sure but I think it will have a wet kit. It will have an APU it’s one of the three Kenworth’s W990 in the fleet odometer will be roughly 140,000 miles

Over kill for the trailer. Wanna guess what it weighs?

2020 MACK ANTHEM 84T For Sale in Clearwater, Minnesota
This would be ideal for youcke, Oxbow, Diesel Dave and 3 others Thank this. -
Just a tip - if you are thinking you are going to be heavy on the drives - open the trailer 2-4’ and move the load to the back of the well. This will move weight to the trailer axles.
cke, kylefitzy, Albertaflatbed and 5 others Thank this. -
I don’t feel comfortable learning it on my own. I’m sure I can figure it out but I would grind those gears and possibly ruin the transmission. I like automatics.

No. 18,000 hours. 300k+ miles. Hard parts to get for Mack. They are a Volvo. I’m more of a kenworth. Just cosplaying as a freightliner.

I’m not saying that exact truck. I’m saying those specs, but you do you. I will politely stay out of your way.Last edited: Oct 23, 2025 at 7:47 PM
