A bone stock torqueflite is designed primarily to be driven in drive, not manual low.
An educated driver may select manual low perhaps if pulling a heavy trailer up a hill or descending a steep hill and needed engine braking and wanted to protect the roller clutch. But applying the band in normal drive gives a terrible 1-2 shift. That’s why Chrysler does not apply the band in normal drive.
The roller clutch is designed to be able to withstand normal everyday driving.
But the trans was not designed to withstand a neutral drop at 5000 rpm.
