Will/Does Auto Tranny Work With 6.0?
I ask this question, because I have a 6.0 with auto tranny. I am currently using my truck to build my new home, and this truck will not move when parked on fresh graded dirt with a trailer attached. It will not spin the tires, either. The scenario is: pull utility trailer onto site, stop, and then to get going again, I need to floor truck, wait for up to 20 seconds while truck spools up, and starts to build enough power to begin moving. Now mind you, by soft dirt, I am refering to dirt that the truck sinks into maybe 1 - 1 1/2", and for a trailer, I am refering to a single axle utility trailer, EMPTY!!! The truck is very slow to spin up, and the truck will not move until the engine is spinning above approx. 2200 rpm. It scares me to floor a vehicle and wait for 20 seconds for something to begin to happen. When it does happen, I am concerned that it might just take off and get me into serious trouble, or break something since the engine is getting into its optimal power and torque range at these rpms. Can this operation be correct?
BTW, I usually shift into 4lo to move the trailer on site since I have been unable to get truck to move in Hi range. Maybe a standard would have been a much better option for my use!

Are you in drive when this happens? The torque shift tranny will not start out in first gear unless you are in drive, if you are in 2 or 3rd thats what gear you are starting out in. IF you are in these other gears then I could understand this situation, or if you have just started a cold engine, it doe take a while for it to warm up and will do this as well.

The engine is warm, I just towed the trailer to the const. site. tranny is always in drive or reverse. When I left the site, I drove down the highway and it felt like the truck had something holding it back. I pulled over, and when I went to shift into park, a loud clunk under the truck similiar to the sound when you first start up the truck after it has sat for awhile, and the climate control door opens or closes. Except, this was much louder and more pronounced. This has happened several times now to me also.

The tranny is in gear, and the engine is spinning against the tranny. The engine is just not putting out enough torque to move the truck. As soon as you shift into gear, you can feel the tranny engage. As you try to accelerate, the engine builds speed very slowly, because it is trying to move truck. Not until the rpms get up high, in excess of like 2500 rpm, does the truck actually begin to move. To build to this much rpms, it takes a long time, 15-30 seconds.
The frustrating part about this is I am only pulling a little utility trailer, maybe 1000#s. My contractor has a dodge cummins, he pulls a trailer with 20,000#s of equipment on it on the same site with NO PROBLEM. My truck is suppossed to be better, more powerfull and all that, He laughs!!! Yet he complains about problems with his dodge and wants to get a ford. I think he is rethinking his desires seeing how well mine is performing next to his.

somethings not right with your tranny. I pull my loaded horse trailer though mud and soft dirt from stop all the time [around 9000 pounds loaded]with my 6.0 and torqshift and I have no problems.
question do you have tow/haul engaged? it does make a big difference under load.

Are you saying it takes 20 seconds to spool up to 2200 RPM's? If so ignore the rest of my post. If it is taking that long to spool up, there is something very wrong with the engine. You are also going to fry the tranny by not moving while sitting this long with the RPM's going up.
Try starting off with the gear selector in first once. Maybe the tranny isn't starting in first gear? Or it's low on fluid? There's a bunch of solenoids in the TS, maybe some are plugged and you aren't getting the pressure in the tranny to take off.
