Holy Smokes!!! Is yours manual? If you got 22mpg loaded, I should have been able to get more empty, then again, if you have done more with the intake side, among others, allowing the engine to breathe, I can see it being possible.

 

So if you down load the "Overdrive" software your transmission is now "optomised" right? The word "optomised is a bit subjective. I guess what I am saying is I see people posting how good the software upgrade is but no real specific details.

Is this software addition user adjustable or only comes one way?

I am looking for better towing performance and management from the transmission. I would like the torque converter to lock up sooner (lower RPM). Would also like it to lock in second gear at assist with heavy towing loads and minimize heat build up with stop and go / slow traffic. Also would love to be able to limit gear kick down and gear hunting ( ah la manual valve body). In other words once the torque converter is locked out, I want to be able to floor it and not have the transmission kick down and keep I want the torque converter to ay locked out.

Thanks

I have 40k since adding the mini with the overdrive software. The tranny shifts without that darn yank clunk feel. It is more solid when it shifts with a load. Like others have said you can put the cruise control on the hills and never touch it. I have a tranny gauge and it lowered my temps 20 degrees in the 6 plus degree hills in Northern Cal and Oregon. I kinda put it in my mind that it was a electronic shift kit without having to drop the pan. Cost is less overall than dropping the dang pan. It is not a miracle software device turning your truck into a space shuttle. More trans pressure to help a weak link in the drive train.

 

Unfortunately it isn't user adjustable. I really hope this will be a feature H&S adds when they ever get off their rear for the Active Maxx for the Cummins. Another downfall I have noticed is that it the TQ won't lock in 1st or 2nd gears. The only time i have seen it locked for 3rd (briefly) was with the EB on. I have not pulled anything yet so it may very well lock up in the lower gears with a load...but I don't know. 4th - 6th gears depending on the speed or if you have the gear selector set to one of those gears, the TQ was always locked up and it would be instant power to the wheels...unlike the stock trans tune...well you know how it is. The Black Maxx also tells you what gear your in and what gear the TQ is locked.

 

Torque converter will lock in 2nd and 3rd, upshifting or downshifting both...but I've only seen it above 23-2500RPM.

At least on mine, but I do drive with tow/haul on ALL the time!

Yeah, your right. I tried it today with tow/haul on and off and the TQ locked around the same RPM's regardless of the tow/haul setting. Still couldn't get it to lock in 1st.

I don't know if can be done on these newer trucks, but I heard of a switch being wired up to lock the TQ on the older ones.

 

Well ordered my Mini Maxx and Overdrive today. We will see what happens.

3.73 with the 68RE is just perfect.

I got the 3.73 with the G56. Its like the 68RE with the 4.10s

 

How much does the overdrive software cost?

 

overdrive software $299 I believe to get the unlock code for your H&S programmer from thier website.
