Default torque converters truth or myth

i have read that the factory drive train from dodge doesnt do that good of a job transfering the power the the ground. the only thing that i can see to change would be the gears and the torque converter the gears seem to be a good move and what i have read from the advertising the tci torque converter would be a good addition to the drivetrain as well any and all input would be greatly appreciated

Truth, Dodge Trannies are among the least efficient on the planet. A 345 HP Hemi in a Dodge Truck usually dynos about 235-240 RWHP...

So what is the answer here? Modify the stock trans? Replace the stock with aftermarket? or just fit a stick shift trans? What's available out there to remedy the situation?

There are some really bulletproof trannies out there in the aftermarket that are much more efficient, but I'd say the most cost effective solution is to get replace the torque converter...

HammerZ71- Thanks for the interesting information. How much of an improvement will an aftermarket torque converter help with the dyno #'s with regards to HP and torque?

Yes come on Hammer enlighten us as I am busy collecting parts to make my driveline bullet proof! Just as Dodge should have done in the first place!

Thanks for any help and advice.

You want to go fairly high for better performance but the higher you go, the less "streetable" your ride will be.
I'm more of a suspension, lift & exhaust tinkerer, so that's a question I'm gonna leave for the more performance experienced guys to answer. Might be you need to ask the place your looking to buy from or find you a good performance shop to give you a little guidance...

what exactly does a higher stall speed do? and why does it make it less streetable?
