Duramax diesel transmission?

[rdam]

Stay focused. /forums/images/graemlins/grin.gif Any durability issues with the Duramax/Allison combo. Especially 2001 which is when I think they first used the Allison tranny.

Don't want to hi-jack Pete's post, but I'm trying to save server space and get to the people in the know

I love the Allison and adore the Duramax. I've only got forty plus thousand in a little over a year. But I weigh fourteen thousand before two hundred pounds of pure love crawls behind the wheel. I often drag a trailer with a tractor and or materials on it.

The only glitch I've had involved a plugged fuel filter last October.

Oh, there was the hiccup with the Allison the first week I had it. The truck stopped shifting into overdrive. I took it in that morning, a saturday, and the tech couldn't find the problem and suggested I bring it back Monday when the guy who'd went to school on the tranny was in.

Monday morning on the way to the dealer I happend to notice a little light was on with one of the many buttons on the dash. I didn't know what it was but I pushed it to turn of the little light.

Tranny shifted into overdrive and I hung a U turn at the first opportunity. /forums/images/graemlins/blush.gif /forums/images/graemlins/blush.gif /forums/images/graemlins/blush.gif /forums/images/graemlins/blush.gif

Wroughtn_harv,

What sort of gas mileage do you get while pulling your trailer?

My father in-law pulls a 7x16 enclosed trailer almost 300 miles a week and he's not fully comforable with the Ford Powerstroke's performance. I'm not sure if his expectations are too high or what.

Sometimes I wonder if, in his case, a bigger motor would be better. /forums/images/graemlins/confused.gif

My truck weighs fourteen thousand pounds before two hundred pounds of pure love crawls in behind the wheel.

My trailer with the JCB165HF and attachments at another ten to twelve thousand.

I get eleven plus when I'm running just the truck and keeping it at sixty five or lower. Ten when I'm holding it between seventy and eighty (don't tell).

With the trailer and holding it around sixty five to seventy I get around eight and a half to nine.

I know this sounds terrible.

Unless of course you're in my shoes and the 97 3500HD with the big block couldn't get ten miles per gallon if you through it out of an airplane. With the trailer and tractor I was looking at five, six, six and a half if I was holding my mouth right. Empty I felt like Lucy Light Foot on the dance floor if I got eight.

Power is all relative. I'm sure the power curve in my truck has a lot to do with the gearing.

I doubt seriously if there's a noticeable power difference between a Powerstroke and the Duramax in comparable vehicles. There might be. But if there is I'd suspect it's a lot more to do with individual vehicles versus brands as a whole.

What might be interesting would be to get some feedback from owners on the durability of the accessories etc.

I'm twixt and tween chewing up nails and having a snot slinging fit over things like power windows that don't work and power locks that sometimes don't.

I bet I'm not the only one.
