ISX: Wanna come to Virginia for a weekend?

That is exactly normal behavior for the trans when self-managing as far as my decade of daily driving an RE trans in my Dakota taught me.

What are you used to for mileage, BTW? I usually get 12.5 empty around town, and the same or a bit less on the highway towing. I've always blamed the 4.10s. Everyone who gets 20 or better has 3.55s.

[Rogan]

that's about what I'm used to with this truck.. But it seems to stay pretty steady, regardless of empty or towing.. 11.5-12.5. Last tank netted 8.9 or so, and I about shat.. My '96 had 3.55s and an auto. Got 14-15 city, 18-20 highway. swapped in a 4500 and that jumped to 17 city, and a LINY round trip netted me 27.9mpg @ 68mph and a killer 2200rpm drone headache from the 7" muffler-less stack.. LOLThis 3500 has been a freaking headache since day one. Sure miss my '01 6 speed, but I think I miss my 12V '96 more :)How you liking the Eaton, now close to 3 yrs in?

Alright its 97-99 that had that style filter. Before was spin on and after is those snazzy ones.

If you had a banjo bolt that goes into the supply line on the side of the pump with 1/8" NPT threaded into it for a fuel pressure gauge, would that solve your problems?

[Rogan]

that would solve my 'check fuel pressure' problems, yes LOL

[ISX]

Hmmmmm

If I leave it alone, the 1-2 and 2-3 shifts stay the same, then it'll usually shift into OD shortly thereafter, and slip like a mofo, then LU ~40mph and the slipping stops (obviously)

Funny, that's exactly the bolt of mine that got drilled and tapped for my garbage picked fuel pressure gauge.

Why's it funny? Am I saying something wrong Making me worried now

Rogan, just a little FYI, the PCM on your truck looks at the TPS and the speed sensor on the side of the transmission to determine what gear to be in. If the TPS is producing lower than 'normal' voltage the PCM thinks you are just babying it.
