looking on the parts screen right now it shows the number is a 24228708. the damn converter numbers change often enough sometimes you have to look them up every update.
that pro-truck converter may have a 7k tow rating, but we'll see how that holds up over even as little as 30,000 miles under that kind of use.
i agree with you marc_w, alot of the issue is in the programming. there is some in the tcc circut of the trans also. keeping the stall as low as 2600 does certainly increase the chance of the converter lasting longer. the more slippage occuring when the converter is ready to apply the clutch, the more material is removed upon apply. this gets much worse as temperatures and load go up. on the higher stalls the size of the converter often goes down decreasing the fluid capacity overall and decreasing the quantity of the fluid around the converter clutch which in turn decreases the clutch's heat dissapation. i'm not saying it's impossible to run a higher stall and still use what you drive as a truck, it just makes part failure a considerably higher risk.

I forgot about those TCC apply pressures (and other tables) there too... I remember some people having to mod that table after a converter swap for some reason or another. The lockup was real slow and doggy - something like that.
Just putting the info out here...

They are all correct part numbers but use the one from Zippy as it is most current. The stall is from a Chevy Trailblazer. Should stall to around 2500 or so in a truck.

I look at the truck as being more of a luxury vehicle than a sports car. For me the 3000 would be a little to much. If it was a camaro I would want more than the 2800.
The tune and cam would cause a little increase in stahl. Others have stated a 2500-2600 stahl with this converter.

WE HAVE BUILD A X-CAB 6.0 4.10 GEARS WITH A TRAILBLAZER CONVERTER AND IT PUTS DOWN SOME MID 1.7 60' TIMES RUNNING MID 12.s ALL MOTOR
THE MORE THE TRUCK WEIGHT AND MORE TQ YOU PUT OUT THE MORE IT WILL STALL A TB CONVERTER IS THE BEST ALL MONEY YOU WILL SPEND. IF YOU ARE DON'T CARE ABOUT SPENDING THE MONEY THEN BUY A YANK IF YOU WOULD LIKE TO GET SOMETHING GOOD AND WILL WORK THEN GET A TB CONVERTER AND SPEND THE MONEY YOU SAVE ON MORE HP PARTS AND YOU WILL GET THE 1/4 TIMES DOWN
