sorry for the delay. when you press the accelerator the first time, do the revs go up, or not?
so the revs go up and those revs are not translated to road speed?
the problem is internal to the transmission or transfer case. I would suggest having the vehicle raised and replicating the issue, then the cause can be traced with a mechanics stethoscope or similar. It is likely the transmission in which case I would have the software updated and the transmission reset, but it may require a rebuild / replacement
