Thanks for your reply. I want to know if the planetary gearsets from the 4700 can be changed. Specifically, the 4700RDS has a 4th planetary...
Are there any Allison Techs or Engineers on here? I've got some technical questions about the 4500 and 4700 transmissions.
14L with EGR delete and I suspect a bad tune.
Ok. I've got a fuel sucking Detroit Series 60 DDEC 6 but I am super confused as to which turbo type will give the best fuel economy. The pre...
I have put 60,000 miles on my truck since the inframe 8 months ago. Getting 5.5 MPG now instead of 5.2, doesn't use a drop of oil between changes...
Hi Greggg, I know that this post is almost 3 years old but what kind of mpg increase did swapping the 14L to a 12.7L turbo get you? Was the 12.7...

I have to put my low fuel economy issues on hold while I track down another random problem. While bobtailing to get my next load, the Eatob...
Thanksfor your help and time.
Wow. Great info. There's no way to add water from what I can tell but I will see about adding some. I can't borrow an amp clamp but will fix the...

@RocketyMan, your post is unbelievably helpful. I reconnected the sense wire and now my alternator puts out 14.1 to 14.2 volts. Turn on the...
Is that all it does? I had to replace all 4 batteries when I bought the truck so is it safe to put it back?
