tow/haul mode

Does the 3.0 ecodiesel have a tow/haul button that we need to press before towing? My last jeep with a hemi motor had one.

No buttons now - torque + 8 speed auto = no buttons!

Re: tow/haul mode

Optionally you could take it out of ECO mode or even go to Sport mode. Either will cause shifts at a higher rpm and assist with towing in town and lower speeds in hills.

Re: tow/haul mode

Diesel pickups still have tow/haul mode, so just because we have small diesels, doesn't mean we couldn't benefit from a tow/haul mode. I'm surprised this wasn't a feature, but like already mentioned, sport mode is pretty close to what tow/haul does on diesel trucks, maybe except the increased engine braking.

Re: tow/haul mode

The tow button is in previous trucks to limit the torque In overdrive by changing the points that it downshifts. This is due to the weakness of the transmission and its ability to stay within operating temperatures. If I recall correctly, some tow modes restrict overdrive completely.

Our ZF is much beefier so perhaps it isn't needed. The Aussies have been towing with the VM3.0 for a while now with no complaints.

Re: tow/haul mode

I have GC 8 speed trans with sport mode, and also paddle shifters.

The 8 speed is silky smooth,can barely feel it shift in auto mode.

You can limit the gear selection for towing which is 7200# on my limited.

Mine has the trailer tow option with rear self leveling shocks.

800 amp battery,220 amp alternator.

Hill start assist.

The trailer package also has an anti sway program built in which is part of the electronic stability control system .

The limits are 64sqft frontal area of trailer and 30ft in length.

The 30ft kind of scares me.



I had to experiment some to get you the answer.

On the new Jeep there is no L1,L2,L3. You have D/S = Drive/sportmode on the shift lever.




NOTE: Step 1) When Selec-Speed or Hill Descent Control is enabled.

2) Paddle Shift mode is not active. Pressing the (+/-) shift paddles in Selec-Speed or Hill Descent Control simply limits the highest allowed gear.

3) Shifts below and up to that gear will occur automatically.

Hill Desent Button is below 4wd low.





BY limiting the trans shifting from 8th gear or any other gear which = Over Drive your trans will not be hunting gears while climbing hills or MTN's this will keep trans temps down!!

Its better on all equipment if you do not lug your motor, if you are in the proper gear for the hill/mtn you are climbing keep rpms down so you are not over reving the motor for the gear you are in and just be happy your still going up at snails pace if need be.

By Limiting gear choice you can keep the motor in the sweeeet spot 1700-2000 rpm where our motors make the best power and torque and should be unstoppable pulling.

Remember you are responsible for what is on your trailer you are towing and the people around you on the roads.

God forbid if you were in an accident overloaded or load not secured properly and the load you are pulling kills someone it will be a butt pucker moment.

Re: tow/haul mode

When towing in manual using paddle shifters, does the transmission shift gears at reasonable RPMs or does it do so at extreme limits (near idle and redline) as a protection. I don't think manual mode will manage gear selection adequately for towing. I know it doesn't for daily driving. All shifts are at operating extremes and manual gear selection is required to avoid this.
