I have an 04 supercrew and I pull a trailer with it almost 99% of the time. I am wondering if there is a way to program it so the overdrive is always off unless I want to turn it on?

 

I to wish there was a way to do this. I think they should come from the factory this way. Try turning it off in town and see how much better your truck responds.

 

A long time ago someone posted a product here that does just this. It was an electronic box that reversed what the shifter OD button does. So, basically, the OD is normally off. I tried to search and find the thread and I cannot find it. I also cannot remember the name of the product myself (sorry). If anyone remembers this product or thread, please refresh our memory.
