I have a 2021 Freightliner Cascadia. For about the past week or so, when I am doing a back, and I put the transmission in reverse, I ease off the brake and I don't touch the accelerator at all, the truck will lurch backwards like a rocket. I used to be able to back into a (tight) parking spot at a truckstop slowly and gently. Now the truck wants to move backwards like a rocket when I ease off the brake, and if I press the brake again to try to slow the truck down, it is hard to slow the truck down without just stopping the truck altogether. So, frequently, when I try to slow the truck down (without trying to stop the truck), the truck will violently come to an abrupt stop.
I don't notice the truck's engine moving too fast forward when I am driving forward with the transmission in drive. Now I know that it doesn't make sense for the truck to move excessively fast without pressing on the accelerator in reverse but not seem to move excessively fast without pressing on the accelerator in drive, but that is what it seems like it is doing.
Before about a week ago, my truck would only move about 1 mph in reverse on flat ground if I did not press the accelerator or the brake pedal. Now, my truck moves about 5 mph in reverse on flat ground when I don't press the accelator or the brake pedal.
Does anyone know why in the last week or so, my semi-truck started moving in rocket speed in reverse without my even touching the accelerator at all?

sounds like it's in high range.
your splitter might not be working rightRideandrepair and buddyd157 Thank this. -
if one swiftly shifts into reverse, there is "no time" for the transmission computer to know what was going on, and keeps the trans on the high side.Flat Earth Trucker, Rideandrepair, expedite_it and 1 other person Thank this. -
only drove an auto once to do a local load.
early days of autos and that was enough.Rideandrepair Thanks this. -
called the shop, was told shut down the engine for 10 full minutes, try again.
that worked....
which is why, i'd rather have an automatic car, or pick up truck, over any 18 wheeler any day of the week, and twice on sundays.Rideandrepair and Numb Thank this. -

if not that, then a reset of the computer is maybe needed. by removing a the negative cable for about 5 to 10 minutes, then reattach, start up, let idle for about 5 to 10 minutes to let the 'puter relearn the parameters.expedite_it Thanks this. -

Sounds like its in high range or maybe high split? Don't know how many gears you have in that one.
