1st and 2nd gear positions cause the PCM to remap the throttle
essentially the throttle gets cut in 1/2 by placing the shift lever into 1st or 2nd. the throttle then is more "sensitive" and you have better control of the wheels.
this is achieved because you now have full pedal travel to control only 50% of your normal throttle...so you don't inadvertently spin the tires by giving it too much gas
it's a little known feature to help you control low speed situations. like boat ramps, towing heavy loads, 4x4 offroad
This is a response from Tylus on the FTE forum regarding the same issue, if it is the pcm remapping the throttle I would think it could be programmed to not do it. Or, perhaps there is a microswitch somewhere that can be bypassed. What do you think Bill?
