That thing will be toast via heat buildup! Hahahaa. Sorry. But that's more along the lines of a 4500lbs capacity IMO.
They are probably just a hi-energy internal clutch or a carbon fiber base. Despite these havin a clutch apply area equal to or greater than the stock converter I don't see anyway you can tow that much like they say and not kill the converter and trans. Towing creates LOTS of heat in the converter espically when of a higher stall.
If you plan to tow...just go with that TT3000. It's ~11" and should be able to dissipate the heat a lot easier.

I didn't say the holding capacity was the problem...the physical size of the converter is for that much weight to pull.
I can build a triple clutch 9" converter that would be about 2.5X the stock lockup capacity. Would I tow with that? Hell no. The size of the case is the limiting factor there. It simply can not be rid of the heat quick enough like a 12" case can.
Still think I am full of ****? Go call PI and ask them what they think about towing with a small case converter even with multiclutches...I bet they won't recommend it either.

Yeah I would tow light stuff (3000lbs or so) with no problems on a multiclutch 10" converter. 7000lbs is my truck's + ~2000lbs more OR a CCSB 4x4 2500HD... that's a lot of weight for a 1/2 ton truck let alone on the 10" converter.

With the PT3400 might be as good as a .6-.7 second loss in ET. For street use, the only difference you would notice would be the PT line would be slightly looser. But it will still outpull the TT line on the street with the extra shift extension. It might not make as much power unlocked on the dyno, but the extra RPMs it pulls on the shifts makes up for that.
Edit: I am not counting the TT3200 in the above statements. The TT3200 should be an even better converter, but it can only tow 4000 lbs.

If towing is a concern, the PT3400 would be the best performance TC, BUT if towing more than 4K lbs is not needed, go with the TT3200 for best performance.
