drive problem, manual

have a M40D cat, s/n 4WC01746. No manual.

Have run the diagnostics and everything is ok. The problem is when you step on the accelerator pedal, unit creeps, then takes off. Happens same way forward or reverse.
Checked the drive motor, SCRs, and replaced the throttle control.
Would like a repair manual or if anyone has had this problem

does this condition occur all the time (cold or hot)?
or only happen after the truck has run and gotten hot?

Fact of the week
Bluetooth is named after the 10th-century Viking king, Harald Bluetooth, who united warring tribes in Denmark and Norway. In 1997, Jim Kardach from Intel gave the name to the technology because of its ability to unite different communication protocols, just as Harald united various tribes.
