We just took delivery of a 2010 International truck. It is a 4400 seiries with 2000 gallon of water. It has a 6 speed transmission. My question is should the 6th gear be locked out? We are in southern Ohio nd we have a lot of hills in our area. Our sales rep says we should have the 6th gear locked out to give it more power on the hills. What do you think? Will this help?

As always, its a good idea to listen to the person that Built it, not necessarily sold it.Courage, Being Scared to Death and Saddling Up anyways.

1500: Like chiefengineer11 suggested, we have all of our engines set to operate one gear down unless the driver hits the mode button. This is a real advantage in the city because of the hills. 10% grades are not unusual. However for mutual aid we have runs of 20 mi plus, so getting the overdrive gear when on the road helps like crazy.
being one gear down helps to slow things down in traffic so you aren't over running your siren as well.

We have the Allison 3000EVS_P Transmission. I am going to try to call Allison and get an opinion from them on what we should do.
