boxman- My tranny failed and when I had it rebuilt, I had a commercial 3rd gear clutch installed as well as upgraded accumulators. I can tell you that the truck tows like a truck should tow now. It holds the gears until you really mash the pedal, then it will shift down. There is more control put in my foot istead of the tranny making all the decisions on when it should shift. HIGHLY RECOMMENDED!!

The computer makes ALL the decisions on when the transmission shifts. All the transmission can do is shift when it's told.

Mark,
That was what I thought until the upgrades were made and I am happy to say that it doesn't work that way anymore. It still goes into O/D at 40 mph, but when you have it loaded down, it holds the gears. So, under 'normal' driving conditions I agree that the computer has its way, but when you are loaded down, it allows the engine to stay in the powerband rather than shift unexpectantly. The proof is in the truck.
