I've noticed several other people having the Tow/Haul mode with various years of the Ram 1500, but mine does not have this feature. It's a 2002 Ram 1500 SLT 4x4 with the 5.9l Magnum V8 and a 46RE transmission. Is there an aftermarket feature to put Tow/Haul mode on it or am I stuck turning off Overdrive when hauling?

 

We're stuck with OD off only. If you want that level of control on your 46RE you have the option of converting to a full manual valve body.
