Tow haul and overdrive
Does tow haul lock out overdrive? Mine doesn't seem to or, I haven't observed correctly.

The Op is talking apples and most are talking oranges.
Shifting parameters/clutch locking and unlocking parameters/OD or no OD/the whole tow/haul event depends on the trucks transmission size/year model.
The 6L80e in the wifes 2016 1500 chevy 5.3 (and her old same chevy truck in a '06 5.3 4L60e) has a completely different tow haul operation than my sons 2016 2500 chevy Dmax/A crew cab.
All the tow/haul does in the 1500 '06 and '16 truck is hold the TC clutch unlocked to a higher rpm while accelerating. In fact the TC clutch is still unlocked while going downhill at that rpm/speed. At certain speeds/rpm there is no engine braking simply because the TC clutch is unlocked. Thats why I stopped using T/H mode in both trucks. Neither truck T/H mode locked out OD.
My sons '16 Dmax/A tow/haul works completely different and does a really good job all around.
