Allison Transmission:Does yours work?
Alot has been said about Allison being the best A/T for pickups,but my experience tells me otherwise.Mine has been replaced twice and the third one makes noise and I can feel torque in the drive train imediatly on start-up while still in park.Does anybody NOT have "the noise"?Gm is telling me this is as normal as engine knock or oil consumption.

kip even with 1000lb in the bed and 7700 in tow.
I am coming real close on 5000 miles, but the truck is been sitting for a week or so, as I started to gut it for a new speakers & sound deadening.
So as soon as it warms a little, change out the transmission filter & diff fluid.

When I test drove an Allison last year I thought it to be very noisy. Was told that was the nature of the HD transmission. On paper the Allison looks to be the best auto trans ever for light duty trucks.

Now, my Allison experience. From day one the truck would not hold fifth with a full load per GMs rating. I complained loudly and finally a tech was dispatched directly from Allison for diagnosis. We spent a whole day tugging around 15k pounds hooked to a laptop recording data. About a month later Allison had forced a computer program update through the GM red tape division. My truck now functions perfectly. I have 55,000 miles on the truck now. It works pretty hard, I pull those 10-15k lb loads daily with it. I certainly have not had a failure. I also applaud Allisons willingness to come and address my one truck. Chevy just played dumb, which I believe they are, throughout the whole thing.
I do know from this tech that, in any other application, Allison would alter your transmissions programming to match your application. GM will not allow this. Hence you MUST go through the dealer. Once the update was in the GM system I went to the dealer and had it installed.
The rest of the truck still troubles me. To make this thing a decent hauler you still must replace the worthless side mirrors, little kid tires, and put some decent shocks on it. Then I have had more dumb little problems that I care to list, the most recent was a faulty 4wd switch. Then the radio is a pathetic excuse for tunes in a 40k truck. Rest assured, GM is making big money off of us, because they sure don't put the money into the truck. If I had to do it all over again I would still buy another Ford. It is just a better truck.
